2 Introduction

This document is a Contract-Controlled Document (CCD).

2.1 Intent of Interface Agreement

The intent of this Interface Agreement is to establish effective co-operation between Fujitsu
Services and Post Office Ltd for the timely efficient and cost effective delivery of Operational
Business Change using Reference Data to HNG-X enabled Post Office counters.

This Agreement covers both Product and Branch Reference Data.

This Interface Agreement identifies:

e Post Office Ltd and Fujitsu Services requirement for changes introduced via Reference
Data,

e the agreed end-to-end service solution for Fujitsu Services and Post Office Ltd, both
separately and jointly, for implementing such changes and

e the obligations of both parties, both separately and jointly, that must be met in order to
deliver the solution.

There are a number of documents (which are not CCDs) that describe the interfaces and
agreements made between Fujitsu Services and Post Office Ltd for the management of
Operational Business Changes. This document provides an “umbrella” agreement for those
and they will comply with the agreements made within this Interface Agreement.

Whilst this Interface Agreement serves as an umbrella for other documentation it cannot
supersede any contractual obligations defined within the Contract. The timescales shown
later in this document are those which are agreed by both parties to be operationally viable
and as such form the basis of normal business practice when implementing changes to
Reference Data.

2.2 Maintenance of this Interface Agreement

This Interface Agreement is applicable the HNG-X system. It will be reviewed for any future
major software release and on an on-going basis. It is maintained by Fujitsu Services on behalf
of both parties.

2.3 Future Developments

Post Office Ltd and Fujitsu Services agree to work jointly to improve the quality and
effectiveness of the Reference Data interface as follows:

e Review the functionality, scope and effectiveness of the Reference Data test environment
and enhance where appropriate.

e Continuously monitor the toolset available in the test environment, in particular the
Reference Data comparison tool for identifying impact of planned Reference Data changes
with the possibility of enhancement where appropriate.

e Continuously monitor and where necessary improve the Reference Data Change Catalogue
(RDCC) relating to Reference Data requirements.

e Review the consolidated set of Business Rules and procedures which have been jointly
developed and implemented

e Continuously improve the scope and effectiveness of Business and System tests.

e Identify risks to the Reference Data service and take remedial action to eliminate or
mitigate such risks

The programme for delivery of each of the above will be overseen by the RDORF.

2.4 Service Management Policy

Service Management Policy is described in document SVM/SDM/SD/0007 - Service
Management Service: Service Description

2.5 Alerting when product data is at risk of late delivery

When it is known that Reference Data for Product changes may be at risk of non delivery by
the time it is required at branches (the Effective Date) it may be necessary to alert parts of
Post Office Ltd so that the relevant staff (branch, helpdesk etc.) are made aware that a
required change may not be present when expected. The only time this is a potential problem
is if the data has been released the day before it is due to become effective and there are then
problems in the overnight processing and/or delivery of the data. In practice the majority of
Reference Data is released at least two days before it is due to become effective and therefore
there is only a small risk of an issue arising.

The principles of the process with respect to data being delivered overnight to become active
at branches the following day are:

© to provide warning to relevant parties in Post Office Ltd and Fujitsu Services, that
there is risk of critical reference data not being available at branches the following
day

© to allow appropriate contingency to be invoked against that risk where lack of the
data would cause critical problems

CONFIDENCE)

The process follows the following stages:

© POLRDT (Bracknell) would indicate to RDT (on the authorisation form) that Post Office
Ltd would wish to be informed of overnight processing problems

e¢ RDT would inform FJS duty management and data centre operations that an alert request
had been made

e In the event of overnight processing issues data centre operations would advise the FJS
duty manager of the problem and the FJS duty manager would then advise the Post Office
Ltd duty manager

2.6 Contractual obligations with respect to NBS

The contract for supply of the Network Banking Service included a number of contractual
obligations which have been carried forward into this document.

2.6.1 Extensibility

The NBS shall support, through changes to or the introduction of appropriate Reference Data,
the introduction and removal of new instances of and changes to each of the items (marked as
suffix NWB) shown in Appendix B: Standard Changes — Details. The parties may agree to
vary the allocation of the items from time to time, such variation to be documented by Fujitsu
Services in the working document entitled “Reference Data Change Catalogue”
(RD/CCL/001).

2.6.1.1 Introduction and Change

The introduction of changes to and new instances of items specified above in 2.6.1

(a) shall be effected using only the agreed functions and processes used for
introduction of and changes to reference data for those Post Office Services
existing at the time of introduction of the NBS into this Agreement.

(b) shall not cause to be exceeded:

(i) any limit or range in respect of any such item (including, without limitation,
limits or ranges on the number of IINs) where such limit or range is
specified in the CCD entitled “Horizon Capacity Management and Business
Volumes” (PA/PER/033); and/or

(ii) if no such limit or range is specified in that CCD then a reasonable limit or
range

2.6.1.2 Verification of NBS Reference Data

Post Office Ltd shall be responsible for verifying all NBS related Post Office Reference Data
for use in End to End Banking, save to the extent that Fujitsu Services is obliged to do so (for
the purposes of the use of such Post Office Reference Data within the Post Office Service
Infrastructure) in accordance with paragraph 2.6.1.1 above. For the avoidance of doubt, the
Change Control Procedure shall be used if Post Office Ltd requires, in connection with the
introduction of any of the items referred to in paragraph 2.6.1 above, Reference Data
validation or testing of the NBS (or any element thereof) outside the scope of this Interface
Agreement.

3 Scope

3.1 Interfaces

This Interface Agreement covers all the interfaces between Fujitsu Services and Post Office
Ltd that support the Operational Business Change process for pre-defined Product and Branch
changes.

Interface Interface Interface

Fujitsu
Post Office Services Post Office Fujitsu
Ltd processI process Ltd processI Services
l J * process

* this step is not
needed if change is
pre-authorised

The start is the point where an OBC form has been completed and issued within Post Office
Ltd, and the end point is where the Reference Data has been released within Fujitsu Services
for delivery to the live counters.

The delivery of the Reference Data to counters, following release authorisation, is covered by
the SLT (see section 3.2).

This Interface Agreement applies to both Product and Branch Changes where:

e a Basic Product Change and HelpDesk Branch Change is a change which consists solely of
Reference Data which requires no additional Fujitsu Services actions and may be
submitted to Fujitsu Services without notice

e an Advanced Change Product Change is a change which requires additional Fujitsu
Services activity and is subject to advanced notification

e an Advanced Branch Change is a change which is subject to advanced notification

Note: Reference Data for Branch Change is usually necessary to support activities
such as: a new Branch Opening, a Branch Relocation, conversion of a Branch
franchise, a Branch Closure. Reference Data also supports changes to branch
details such as: opening hours, telephone number, name and address but excludes
the addition or removal of individual counters. The specific activity for branch
change is described in document SVM/SDM/STD/0001 - Fujitsu Services / Post
Office Ltd Operational Business Change — HNG-X Branch Interface Agreement

3.2. Service Level Target

The contractual provisions and service level targets relating to the distribution of Reference
Data to Branches are defined in SVM/SDM/SD/0013 — Reference Data Management Service:
Service Description section 2.3.5.

3.3. Operational Business Change processes for Reference Data Change

The Operational Business Change (OBC) process for Reference Data is defined in document
SVM/SDM/PRO/0027 - Process for Operational Business Change - Reference Data and the
types of change that qualify for the OBC process are defined in the Reference Data Change
Catalogue (RDCC). Changes not found in the RDCC must be requested via the normal
Change Control Procedure.

A summary of the process is given below.

Note:

Not every Change Type follows every step of the process see section 4.2.
The timescales for each stage of the process are defined in section 4.2.
The types of change that the process applies to are defined in section 4.2.
The responsibilities of each party are defined in section 9.

Note: the diagram and description refers to the process for Operational Changes once any
required agreement has been reached regarding the viability of the change (as may be the case
with APOP/ADC changes)

Post Office Ltd I The relevant unit in Post Office Ltd identifies if the

change is a Basic Reference Data change, or an
Advanced OBC change.

The relevant unit raise the required OBC forms to:

e Request Post Office Ltd Reference Data Team
(Bracknell) to change the Reference Data (for both
Basic and Advanced Changes)

e Where necessary POLRDT(Bracknell) raise relevant
OBC forms and send to POLRDT(Chesterfield) for
keying into Post Office Reference Data System

¢ and request an OBC — Product Change from Fujitsu
Services (for Advanced Changes).

Post Office Ltd RDT (Bracknell) confirm the change
requested is an Advanced OBC change and request
Fujitsu Services to make the change.

Post Office Ltd RDT (Bracknell) supply any required
additional information to support the Advanced OBC
change.

Post Office Ltd ensure that all necessary communications
and supporting actions for the OBC are complete.

ensure Reference Data is appropriate for the OBC
requested as defined in the RDCC, generate Type C,
Type F and Type X Reference Data as necessary, test
changes. Changes are tested and validated by Fujitsu
Services where necessary.

Fujitsu Services generates and delivers the RDMC
Verification Report and the Comparison Report to Post
Office Ltd RDT (Bracknell) and delivers the actual
Reference Data change to the verification counters, as
appropriate.

Note: Fujitsu Services does not send Pure Basic and
Migration Special Changes to Post Office Ltd RDT
(Bracknell) for authorisation, as they are pre-authorised
by Post Office Ltd.

4 I Verify & Post Office Ltd I Post Office Ltd RDT (Bracknell) undertake OBC counter

authorise RDT and report verification (as appropriate) and confirm the
completed I (Bracknell) change as delivered is the change required, and authorises
change the release of the OBC to the live estate.

Post Office Ltd RDT (Bracknell) may also request an
alert be raised if the data is at risk of not being available
by the time it becomes effective. (see section 2.5)

N.B. Some changes are Pre-Authorised — please refer to
CS/PRD/108 - Conventions for naming of Operational
Business Change Reference Data

N.B. The following steps may start after step 1 and run in parallel

5 I Review Fujitsu Where appropriate, Fujitsu Services reviews, and
Operational I Services responds to, all relevant Operational Focus or other
Focus update articles before publication and distribution (when
articles required) to confirm that the contents correctly reflect the

system and will not have an unnecessary impact on
Helpdesk resources. Post Office Ltd shall accept all
amendments reasonably requested by Fujitsu Services in
pursuit of the delivery of contractual services.

6 I Change Fujitsu Fujitsu Services releases Reference Data for all
delivered to I Services authorised OBCs to the live estate.
counters Fujitsu Services will raise Delivery Alert on the Release

Day, if the Alert Flag is set and the change is to be
effective next day. (see section 2.5)

Where agreed with Post Office Ltd, the release may be
held pending communication to the Branches e.g. via
Operational Focus. (However if release delay risks the
Start Date, there may need to be another change
processed to amend the start date of the change).

3.4 Operational Business Change processes for Branch Change

The process for effecting changes at branches is fully described in SVM/SDM/STD/0001 -
Fujitsu Services / Post Office Ltd Operational Business Change - HNG-X Branch Interface
Agreement. In some cases there will be a need for Reference Data to support the physical
changes at branches (e.g. temporary closure for refurbishment). In some cases there will be a
need to change Reference Data when there is no physical work required (e.g. change of
opening times).

Whilst the definitive process is in SVM/SDM/STD/0001 it is worth noting the general steps
within this document:

Post Office Ltd submit Reference Data via MDM to RDMC

Fujitsu Services produce reports and send them to the relevant Post Office Ltd unit

Fujitsu Services release the data no earlier than 48 hours after receipt

Post Office Ltd check reports and if errors are found submit a fresh change

Should Post Office Ltd find an error during the 48 hour window a direct request to Fujitsu
(usually by telephone) may be made to stop the release of the data. In this instance the
release is no longer pre-authorised and becomes a change which requires authorisation

weenr

Note: Reference Data for branch temporary closures is only sent by Post Office Ltd to Fujitsu
when the temporary closure is expected to exceed 10 days.

4 Types of Change

4.1 Introduction

Change types are pre-defined for inclusion into the OBC — Reference Data process. This
definition can be found in the Reference Data Change Catalogue (RDCC). Each pre-defined
change type is grouped as shown in the table in section 1.

The RDCC Product Change categories that apply to these changes are listed in sections 4.2.1
and 4.2.3 below. The assumptions listed in the RDCC must be adhered to, in order to apply
these categorisations.

Change types for Branch Changes are defined in SVM/SDM/STD/0001

4.2 Product Changes

4.2.1 Standard Changes

The order of the change types in this section is significant and is an indication of the level of
risk with each type and therefore the amount of checking that is deemed to be necessary. The
change types are of varying risk from those which need little or no checking, as the effect of
an error would be minimal on the Live estate, to those which need extensive checking, as the
effect of an error may be significant on the Live estate. Those changes, which are deemed to
require minimal or no checking, are classified as Basic - Pure. Those changes, which are
deemed to require most checking, are classified as Advanced — Complex or Advanced
Complex Extended.

A complete list of changes applicable to each type is held within the RDCC. Should Post
Office Ltd decide that additional checking is required a change may be submitted in a type
with a higher risk position in this section. However the converse is not true, in that a change
can never be requested with a lower risk position than the type shown in the RDCC.

Appendix A: Standard Changes - Details, shows a representative list of the changes for each
type.
4.2.1.1 Basic - Pure

Basic Changes do not require advanced notification from Post Office Ltd to Fujitsu Services
(OBC form). The delivery of the Reference Data file using agreed mechanisms is the request
for change. The file must identify that its contents are Basic Pure changes. The file may
contain more than one change of the same type. All Basic files contain only Class 1 Reference
Data items. Fujitsu Services checks the contents of the file are appropriate for the type of
change. Pure changes do not require verification and are pre-authorised for release.

4.2.1.2 Basic — High Risk

Basic Changes do not require advanced notification from Post Office Ltd to Fujitsu Services
(OBC form). The delivery of the Reference Data file using agreed mechanisms is the request

for change. The file must identify that its contents are a Basic High Risk change. The file may
contain more than one change of the same type. All Basic files contain only Class 1 Reference
Data items. Fujitsu Services checks the contents of the file are appropriate for the type of
change. High Risk changes require a Verification and a Comparison report (where
appropriate) and authorisation by Post Office Ltd before release.

4.2.1.3 Advanced Simple

Advanced Simple changes require advanced notification from Post Office Ltd to Fujitsu
Services (an OBC form) to request the change. Associated Reference Data files must be
identifiable as such through the BCR number. Fujitsu Services checks the contents of the file
are appropriate for this type of change. Fujitsu Services has actions to take to implement the
change (in addition to processing the Type A Reference Data file from Post Office Ltd) e.g.
update documentation, but these actions can occur after the change has been released and
therefore do not extend the lead-time for the change. These changes require a Verification and
a Comparison report and authorisation by Post Office Ltd before release.

4.2.1.4 Advanced Standard

Advanced Standard changes require advanced notification from Post Office Ltd to Fujitsu
Services (an OBC form) to request the change. Associated Reference Data files must be
identifiable as such through the BCR number. Fujitsu Services checks the contents of the file
are appropriate for this type of change. Fujitsu Services has actions to take to implement the
change (in addition to processing the Type A Reference Data file from Post Office Ltd) e.g.
process Type B files, and these actions must occur before the change has been released,
therefore the lead-times are longer than for Simple or Basic changes. These changes require a
Verification and a Comparison report and authorisation by Post Office Ltd before release.

4.2.1.5 Advanced Complex

Advanced Complex changes require advanced notification from Post Office Ltd to Fujitsu
Services (an OBC form) to request the change. Associated Reference Data files must be
identifiable as such through the BCR number. Fujitsu Services checks the contents of the file
are appropriate for this type of change. Fujitsu Services must generate Type C, Type F or
Type X Reference Data as appropriate to implement the change and then test that the change
works as requested in the OBC form. These changes require a Verification and a Comparison
report and authorisation by Post Office Ltd before release.

4.2.1.6 Advanced Complex Extended

This category of change has been introduced to differentiate from ordinary Advanced
Complex changes as the lead-time is longer to allow for additional validation/verification
which is necessary because of the additional complexity of the change. In all other respects
this category is identical to Advanced Complex.

4.2.2. AP (including ADC and APOP)

AP changes are similar to Advanced Complex changes and require notification from Post
Office Ltd to Fujitsu Services (an OBC form) to request the change. Associated Reference
Data files must be identifiable as such through the BCR number. Fujitsu Services checks the
contents of the file are appropriate for this type of change. Fujitsu Services has actions to take
to implement the change e.g. test Tokens and supply test files to the appropriate Post Office
Ltd Client for Post Office Ltd End to End testing of changes. These changes require a

(as described in relevant AP documentation)

Introduce new AP client, service or token
Change client name (new token data)
Cease AP Client, product or token
Introduce new Smart Card

ADC changes are implemented using the same basic process mechanisms as AP although the
timing may differ.

Notes on AP/ADC and APOP change:

e Changing AP/ADC product details when an end-to-end test file is not required falls
outside the category of AP change and is to be treated in the same way as any other
product change

¢ Ceasing AP/ADC Client, product or token when the service is Live, i.e. it is not being
withdrawn from a current CTO/ADC cycle, is to be implemented as an Advanced Simple
change, with the client service list being amended after the event

e APOP/ADC changes may affect the transaction flow on the counter and the content
(including XML tags by use of an ADC data type with ZZ_IncFields attribute) of client
files. It is also possible that incoming client files (submitted via the EDG gateway) may
have similar effects. For this reason APOP/ADC changes may be subject to advance
notification to and agreement from Fujitsu Services that the effect of the change is
acceptable to Fujitsu Services.

4.2.3 Fast-track changes

4.2.3.1 Basic Express

A Basic Express change is a subset of Basic High Risk changes and must comply with the
definitions in section 4.2.1.2. However, the lead-times (see section 5.9) specified for a Basic
Express change can only be achieved where verification can be performed on the basis of the
Verification Report and not a Comparison Report. The type of change must be such that there
is minimal risk of error occurring elsewhere within the system as a result of applying the
change and is therefore limited to:

Change price of non-value stock

Change price of revaluable value stock *

Change min/max quantity/value

Change Long/ Medium / Short name

Add/Amend/Cease End of Session prompt

Add/Amend/Cease Transaction prompt

Add/Amend branch exclusion for urgent suspension

Note: When a Basic High Risk change is to change the price of revaluable value stock,
counters will prompt counter staff on each of the three calendar days prior to when
revaluation will need to be performed, provided that the Reference Data is already at the
counter. Should a similar change be put through the Basic Express mechanism, this
prompting period may be for less than three calendar days. It is Post Office Ltd’s
responsibility to provide any additional notification required to users.

Where the change is as described above, the requirement for completion within 48hrs may
be extended, if required, to allow for this 3 calendar day period.

4.2.3.2 Migration Special

A Migration Special change is a specific subset of Basic Pure changes and must comply
with the definitions in (section 4.2.1.1). Migration Specials are pre-authorised for release
and no verification is required.

Migration Special changes are additions or removals to the Reference Data defining
which non-core products a particular branch can or cannot sell. This Reference Data is
needed so that the correct range of Products is available at the branch

Note: The term ‘Migration Special’ was originally used during the roll-out of the Horizon
system and although it has no specific meaning in the context of the system today it is still
well understood within users of the Reference Data change process and hence the name
remains for this category of change.

The limits for use are:

© additions to Non-core Product to Branch mappings only

% Reference Data must be received by Fujitsu Services by 10am for release to be
actioned on the day of receipt or a phone call is required before 4 p.m. requesting a
later file to be released

Reference Data files must be identifiable as Migration Specials

Migration Specials differ from the standard Basic Pure change for adding non-core
associations to a branch by virtue of:

the urgency with which the data needs to be delivered to the branch.

Migration Specials refer to one branch or one product — the normal Basic Pure
change may have any combination of products and branches.

Where possible Post Office Ltd should use the Basic Pure change for addition of non-core
association records.

Once Fujitsu Services has confirmed that the Reference Data is of the required type it will
be released to the ‘Live’ environment.

4.2.3.3 Tight Timescales

4.2.3.3.1 Requirement

Fujitsu Services recognises that there may be occasions where Post Office Ltd will be required
to implement changes to Reference Data to timescales which are outside the control of Post
Office Ltd, for example changes announced in the Chancellor of the Exchequer’s Budget.
The implementation of Reference Data in support of such changes must be handled in a very
bespoke manner. Fujitsu Services will use reasonable endeavours to meet the requirements
requested by Post Office Ltd.

4.2.3.3.2 Definition

A Tight Timescale change that cannot be processed using the normal timescales defined for

such a change. It may be caused by either:

* an emergency situation where normal lead-times cannot be adhered to because of legal
circumstances outside of Post Office Ltd control, or

eto allow Post Office Ltd to exploit commercial opportunities

emergency introduction of a Transaction or End of Session prompt to cover legal
obligations (e.g. Money Laundering)

Each instance of such change must be notified in writing by Post Office Ltd to Fujitsu Services
and agreed between Post Office Ltd, Head of Delivery - IT and Service and the Fujitsu
Services Customer Service Director or their nominated authorised deputies.

4.2.3.3.3 Types

Analysis by Post Office Ltd of the business requirements indicates that the types of change that
require to be actioned in Tight Timescales are:

e Price changes
e Emergency cessation of a product

¢ Product introduction or change where the product has been created in advance with
interim details.

a) Price Change

The most frequent Tight Timescale changes are price changes. These may be processed via the
fast-track Basic Express route.

b) Emergency cessation

From the CSR+ version of Horizon the ability to transact a product is controlled by the use of
Item Transaction Modes and therefore these types of changes may be processed via the fast-
track Basic Express route.

©) Product introduction or change (with interim details)

A new product (or product change) can be introduced in advance of all details being available

e.g. to meet a late-breaking business opportunity. Mandatory details should be provided

initially, although some will have interim values

eg.

© product name may be set to “test name” or other identifiably interim name

e the Branch Trading Statement mapping may be to a line marked as “temporary”

e the button for the product may not be introduced until a later date, with the product only
available to be sold by PLU initially

The “interim” product should be verified using standard processes for product change (see
sections 3.3 and 5.6).

To set up the interim product the normal lead-times should be adhered to. When the interim
product cannot be set up with the normal lead-times, it will be dealt with as a high priority
exception (see section 10.3).

The interim details will be later replaced using:
* a Basic Express change for the final information relating to price and name. This must be
identifiable as part of the Tight Timescale change, and will be verified via the Verification

Report for Basic Express, before the change is released

e standard changes that occur after the go live of the product e.g. the introduction of the
button, or the change of the Branch Trading Statement mapping.

4.2.3.3.4 Limitations when information is available at a very late stage

Whilst acknowledging that Post Office Ltd may not have control over legal or governmental
changes it must be recognised that the ability of the end to end process to produce, check,
authorise and release Reference Data takes a finite time and therefore it may not be possible in
all circumstances to meet the requirements. To this end the following are guidelines to the
limitations for Tight Timescales changes where the information is only made available at a

very lat

e stage (e.g. 4 p.m. on a budget day).

The time to key the data into the MDM system, extract and transmit to Fujitsu
Services must be considered (probably a minimum of I hour)

The time that RDMC takes to process the incoming data must be considered
(approximately 30 minutes)

If counter checks at Post Office Ltd are required an absolute minimum of 2 hours is
required for RDT system processing. It is therefore likely that this time will not be
available and therefore checking of the data can only be by review of reports —
minimum of 30 minutes to produce and transmit to POLRDT (Bracknell)

The time that Post Office Ltd will take to validate reports, or view data on counters
should time be available for extract, needs to be considered (estimated as a minimum
of 30 minutes)

In order to meet normal operational schedules, authorisation to release a Tight
Timescales change should be received by Fujitsu Services by 7:30 p.m.

The introduction of new items is impossible overnight. If there is a possibility that new
items will be needed their skeleton data must be set up in advance, as described above
in section 4.2.3.3.3.¢

Changes to Type C, Type F and Type X Reference Data (e.g. for Menu Hierarchy) can
only be achieved within Tight Timescales when sufficient time is available — under
normal circumstances, where the normal lead-time is not available, a Business Critical
Advanced Change may be appropriate

An overnight change should therefore only be of the type which amends the price or
name of items

Reference Data
Fujitsu Restricted(COMMERCIAL IN Date: 08 June 2011

CONFIDENCE)

On the basis of the above timings, the latest time for commencement for an overnight Tight
Timescales change, such as Budget announcements, to be with POLRDT for keying is 5 p.m.
for a change to be checked by report and 3 p.m. for a change to be checked by counter.
Whilst these timings are theoretically possible any error which occurs in data preparation or is
discovered during checking may affect the ability of all parties to complete the exercise.
Therefore, wherever possible more time should be given.

4.2.3.4 Live Fix

The time scale for incident correction is driven by the impact of the incident, the complexity of
the solution and the Start Date (or Agreed Date) for the change to be live at the branches. (see
section 10.4)

4.2.3.5 Business Critical Advanced Change

It has been recognised that the Fujitsu Services and Post Office Ltd operational units have the
ability, in some circumstances, to shorten the OBC lead time without adversely impacting the
success of the change, or any other change in the system.

A Business Critical Advanced Change category has been introduced to permit operational
units to decide, where possible, to deliver change within a shorter time than the specified lead-
time. BCAC does not replace Tight Timescales but rather offers an alternative, operational,
method (similar to Basic Express) of progressing Advanced changes without the need for
authorisation to be obtained at a senior level within both Post Office Ltd and Fujitsu Services.

= Each instance of a Business Critical Advanced Change must be agreed by each of the
groups involved in the processing of the change (normally Post Office Ltd and Fujitsu
Services Reference Data Teams) before the change is submitted to Fujitsu Services for
action. This must include agreement on the effective date for the Reference Data

= The lead-time requirement for such a change must be shorter than that which would
normally be required to complete the change

= The agreed lead-time requirement must be achievable

= Any errors or modifications which occur in the delivery of such a change are likely to
cause failure to achieve the agreed lead-time

= A maximum of I such change is permitted within any single week and 2 such changes in
any rolling 4 week period

= RDORF may, by agreement, modify the maximum quoted above

= RDORF will review each instance of such a change to establish why it was necessary to
invoke this process (without prejudice to any business confidentiality)

4.3 Branch Changes

Note: From June 2005 all branch changes are pre-authorised. Please refer to section 3.4
4.3.1 HelpDesk

Help Desk (HD) changes are those changes which are considered to be of very low risk in the
event that the information is incorrect (e.g. change of a phone number at a branch). They do
not require advanced notification to Fujitsu Services and provided that any file received by

Fujitsu Services only contains changes consistent with being HD then the change is considered

4.3.2 Advanced

Advanced Branch Changes are mostly associated with physical activity in branches. The
Reference Data is supported by an OBC form defining the actual requirement. Reports are
provided to the Post Office Ltd unit responsible for such changes to enable them to ensure
that the change is as required.

5 _ Lead-time for Product Changes

5.1 Introduction

The lead-times quoted in this section are the end-to-end times covering both Post Office Ltd
and Fujitsu Services activities. Each party must meet each milestone applicable to it in order
that the subsequent milestones and the end-to-end lead-times are achieved. The types of
change that relate to each category are defined in (section4.2).

These lead-times apply for the volumes given in (section7).

The lead-time runs from initiating a change until the change is Released to the live system.
Delivery to Counters following release is as described in section 3.2

Notes:
For simplicity, the models used do not show activities that occur in parallel.

day = working weekday (Mon-Fri, excluding English Public Holidays)
adow = any day of the week, includes non working weekdays (Mon-Sun)
times = latest time action can occur to meet the schedule

Where a time is given next to a milestone, the time is critical to achieving that milestone
Where the time is not given, the default is for the handover between organisations to be
complete by 8am. Failure to achieve a milestone by the given (or default) time potentially
extends the lead-time of the change.

Whilst there are indications of the time taken at each stage of the processing these cannot be
taken to be definitive, i.e. the overall lead-time should be taken as the most significant
information.

N.B. The lead-time should be used in relation to when data is required to be delivered to
counters on the Live estate, which may be earlier than the start date on the data

6 _Lead-times for Branch Changes

The lead-times for supplying Reference Data for Branch Changes are defined in document
SVM/SDM/STD/0001.

7 Volume of change

7.1 Committed volumes

The service provided by Fujitsu Services as specified within this document is constructed as
follows

a) it has the capability to handle an overall maximum of 300 business as usual changes within
one month with the following limits within each of the categories

- Branch Changes 140 per month
- Pre-Authorised Product Change 40 per month
- High Risk Product Change 50 per month
- Advanced Product Change 100 per month
- Automated Payment Change 120 per month

N.B. This maximum includes rework, which is expected to be a maximum of 30 files in any
month.

b) to enable Post Office Ltd to manage the volume and categorisation of changes that are
supplied into this service and to facilitate Fujitsu Services capacity management and
alignment of resources to meet these requirements for managing Reference Data changes,
the framework for a Work Index system has been agreed. The Work Index system will
specify in units an indication of the amount of work required for cach file or associated
activity

c) The monthly Work Index limit will be 5000 units which will be equivalent to the workflow
represented by the 300 changes and the identified constraints as specified in a) above

(DN: It has proved impossible to create a direct correlation between 300 changes and 5000

work units due to the fact that the two figures are measuring completely different things

changes is a simple statement of the number of individual requests whereas work units reflect
the effort required. This needs further consideration for a future release of this document]

The Reference Data Operational Review Forum will oversee the introduction of the Work
Index system and will be responsible for its continued development. The RDORF will monitor
and review the effectiveness of the process and any issues which arise from these limits.

Data, which is required specifically for the implementation of a new system release is
exceptional to these committed volumes and as such will not be counted within any
measurement against this Interface Agreement.

8 Deliverables

To ensure milestones are not put at risk all deliverables must be:

Complete and identifiable e.g. cross referencing change numbers

Error free (see section 10.4 for managing errors)

Correctly dated (see section 8.3)

Delivered by the relevant deadlines set out in the Interface Agreement (see sections 5 and
6 for required milestones)

© Delivered through the agreed mechanisms.

eecee

8.1 Post Office Ltd to Fujitsu Services
Post Office Ltd shall deliver to Fujitsu Services:

1) Reference Data for Advanced and Basic changes

2) Operational Business Change forms for Advanced changes

3) Supporting items and/or information appropriate for changes e.g. AP tokens, Operational
Focus

4) Authorisation for Advanced and High Risk Basic Product changes and Advanced Branch

changes (where appropriate)

Note: This applies to changes which are within the scope of the OBC process, i.e. following

agreement where necessary for changes such as APOP/ADC.

8.2 Fujitsu Services to Post Office Ltd
Fujitsu Services shall deliver to Post Office Ltd:

1) Reference Data direct to Live Counters, for OBCs that are pre-authorised by Post Office
Ltd.

2) Reference Data to Verification Counters, for Product Change OBCs to be verified, and
that:
e include Type C, Type F or Type X Reference Data for Advanced changes when

necessary

e has been validated to ensure changes work as requested on the OBC forms.

3) Verification and Comparison Reports (as appropriate for Product Change) that identify
exactly what changes to the counter have been implemented

4) RDMC report (as appropriate) for Advanced Branch Changes

5) Reports to RDORF on volumetrics

8.3 Future Dating

Reference Data records contain either a ‘Start Date’ or an ‘Effective Date’ which is the date
on which the change is to become effective on the counters. Where possible this date should

CONFIDENCE)

always be in the future when the data is created and remain a ‘future date’ throughout
processing and distribution so that it is still a future date when it arrives at the counters.

However it is advisable that the future date is within the range of dates available on validation
and verification counters (currently a maximum of 12 weeks) as it may not be possible to
validate/verify a change which is further in the future. Furthermore, if the change has more
than one effective date (e.g. Remit In followed by Serve Customer) and the difference between
these two dates is more than 4 weeks less than the maximum date range of verification
counters (i.e. a maximum of 8 weeks between start dates), the change should be submitted as
two separate changes to allow validation of the individual parts. Failure to do this may result
in the second part of the change having to be released before it has been validated.

There is a risk to Post Office Ltd if the OBC process is not initiated sufficiently in advance of

the Effective Date to allow for:

e the IFA lead-time for processing, validation, authorisation and release to the Live system
for that particular type of change

¢ the distribution time to branches

e additional contingency where Post Office Ltd consider the Reference Data to have
business critical importance

Where, for whatever reason, Post Office Ltd are unable to initiate the OBC process
sufficiently in advance, then Post Office Ltd and Fujitsu Services would establish an Effective
Date to supersede the Start Date.

Fujitsu Services reserves the right to log as a pre-live incident, the receipt of any Reference
Data which is not future dated. This is because data which has an immediate start date (i.e. any
date in the past at the time when the data reaches the counter) may have an adverse effect and
may create additional calls to HelpDesks.

The scheduling of non-future dated data by Post Office Ltd delaying authorisation of the
release of Reference Data is not an approved method.

9 Roles & Responsibilities

The primary interface for changes described in this document is between Post Office Ltd
Reference Data Team and Fujitsu Services Reference Data Team. Where other units within
each of the organisations requires an interchange with the other organisation in relation to a
business as usual change they should address their requirements via the appropriate team.

Business tests for the purpose of verifying changes to Reference Data are conducted by Post
Office Ltd and are described in OSG/OPS/001. These tests include, where appropriate,
review of Verification and Comparison Reports and the functional testing of Reference Data
on test counters supplied by Fujitsu Services. Authorisation from Post Office Ltd to Fujitsu
Services to release Reference Data is made on the basis of these tests.

10 Orders and exceptions

10.1 Release of Reference Data

The release of Reference Data shall be in accordance with details in document
SVM/SDM/SD/0001 — Reference Data Management Service: Service Description section
2.3.4. Specifically the Agreed Release Date (i.e. Day A) for each change shall be set on the
following principles:

1. The date by which the Reference Data is required to be effective on the counters in the live
estate is the “Effective Date”

2. Where the Authorisation Date is 10 days or less before the Effective Date the Agreed
Release Date will be no later than the next Working Day following Authorisation.

3. For the avoidance of doubt, for Tight Timescale requests in accordance with paragraph
4.2.3.3 of this document, the Agreed Release Date shall be the same as the Authorisation
Date.

4. Where the Authorisation Date is more than ten days before the Effective Date the Agreed
Release Date will be no later than the first Working Day following the tenth day before the
Effective Date

5. If there is more than one set of Reference Data which needs to be released at or about the
same time and in the view of Fujitsu Services releasing all Authorised data would impose a
risk on the delivery of some of that data, in order to achieve maximum distribution by the
Effective Date:

a) the order in which Reference Data will be released will be based on business
criticality of the Reference Data, as assessed by Post Office Ltd and by agreement
with Fujitsu Services

b) anew Agreed Release Date will be agreed for any Reference Data changes which
are delayed as a result of modifying the order of release of the changes

10.2 Orders

¢ The receipt in an agreed mailbox of the OBC form is the confirmed request from Post
Office Ltd to Fujitsu Services, for Advanced Branch Changes.

e The receipt of a Reference Data file containing only Basic (Class 1 or HD Reference Data)
in the RDMC, is the confirmed request for change from Post Office Ltd to Fujitsu
Services.

e The receipt of a correctly completed Authorisation Form from Post Office Ltd is the
confirmed authorisation to release the change.

e The receipt of pre-authorised change files (e.g. Migration Special, Pure Basic, HD, branch
change) clearly identified as such and containing that type of change, is the authorisation
for release of the changes.

© Requests for non-OBC changes (i.e. those not defined in the RDCC), unless agreed by all
parties in advance of any update to the RDCC, will not be accepted and need to be
submitted as a formal (non-OBC) request to Fujitsu Services. However, the change
request may also initiate an update to the RDCC so that new changes are introduced to the
OBC process, where agreed. In many cases once a formal request has been approved the
delivery mechanisms will be the same as, or similar to, those used for OBC.

10.3. Exceptions

Exceptions, e.g. to volumes or lead-times, will be processed using available resources without
any guarantee of service delivery. Both Post Office Ltd and Fujitsu Services shall notify the
other party when a request is recognised to be an exception.

Note: An agreed Deviation to the Service (e.g. Reference Data necessary for the
implementation of a new system release such as Network Banking) is not an exception.

Post Office Ltd may wish to change the priority of an exceptional change so that it is given
preference over normal changes. In this instance the agreed lead-times may be extended pro
rata for displaced activities.

10.4 Errors and Rework

The Volume of Reworks for BAU changes is included in the limits quoted in section 7.1 above
but is expected to be a maximum of 30 per month for BAU changes. This section relates to
errors or rework for both Product and Branch Reference Data, where appropriate.

Fujitsu Restricted(COMMERCIAL IN Date: 08 June 2011

CONFIDENCE)

All observed errors will be recorded as pre-live incidents in accordance with the OLAs
RDS/OLA/001 and PON/OSG/OLA/001. The change will be suspended awaiting corrective
action, potentially delaying the achievement of that milestone for all changes affected by the
error. For example, a file containing records that are rejected will not be processed until the
rejected records are corrected and any other change which is in any way associated with the
rejections may also be delayed. Where the achievement of a milestone is at risk, corrective
action will be taken by the appropriate party or parties, by agreement, in order to achieve the
final milestone, where possible.

A pre-live incident will be raised for late deliverables.

If the Start Date or Effective Date contained within the Reference Data record is not future
dated or is set to a date prior to the Required Date a pre-live incident may be raised i.e. the
Start Date/Effective Date is either prior to the date on the OBC form, or is not consistent with
the overall lead-times (see section 8.3).

If it is known that the final milestone will not be achieved, or an alert has been requested and
the data is being released and will become active on the following day an Alert may be
necessary as described in section 2.5.

Pre-live incidents are recorded on the Peak system used internally by Fujitsu Services Ltd. As
some Peak’s relate to work required by Post Office Ltd it is necessary for Post Office Ltd to
have visibility of Peak data. Details of the passing of information between Fujitsu Services
and Post Office Ltd are shown in Appendix B — Peak control between Fujitsu Services
and Post Office Ltd.

10.4.2 Rework categorisation and thresholds

Rework files are files which are, or appear to be, either Amendment files or Error Corrections
files to a change that is currently being progressed. They necessitate additional activity by all
parties and as such may have an impact on lead-times.

Appropriate steps shall always be taken to establish and eliminate the root cause of Rework.
This will be monitored by the RDORF

10.5 Escalation

Disagreements about the service e.g. whether a change is exceptional, will be raised, and
wherever possible resolved, at the RDORF. If agreement cannot be reached at the RDORF,
either party may invoke formal escalation mechanisms.

10.6 Charging

e AP Client Take-On (including ADC and APOP) is charged as specified in the Agreement
¢ Deviations to the service will be charged as per the Commercial Terms.
© Invoices will be raised and paid in accordance with the Agreement.

Section 4.2.1 gives details of the hierarchy of changes which are Standard Changes. The
complete list of changes applicable to each type can be found in the Reference Data Change
Catalogue . Below is a representative sample of the changes for each type.

N.B. It should be noted that whilst a change may fall into a specific category if there is an
associated change which falls into a different category with a longer lead time on which the
first change is dependent, both changes will adopt the category of the second change.

PAF monthly update
Note: the data centre activity for delivering the PAF update into the Live
BRDB only occurs on Sundays. In order to minimise the delay in getting the
monthly update into the Live service it is important that the update is received
by RDT no later than midday on a Friday so that the release to Live can be
achieved by the following Friday. If the update is not submitted to RDT by this
time release may not be possible for a further week.

The introduction of Chip and PIN functionality means that changes of ITN for Chip and
PIN cards now fall into this category due to the fact that IIN data is also held in the
PinPAD and amendments to PinPAD data require action from Fujitsu Services. Any
other changes to data held in the PinPAD will also fall into this category.

12 Appendix B - Peak control between Fujitsu Services
and Post Office Ltd

Please note that the Peak system has replaced the previous system called PinICL however the
two names are often used interchangeably.

This section describes the agreed mechanisms for passing Peak’s from the Fujitsu Services
Peak system to Post Office Ltd and entering responses from Post Office Ltd into the Peak
system. The passing of data between the organisations is necessary because Post Office Ltd
do not have direct access to the Peak system.

The interface for all Peak’s relating to Reference Data for both the Live service and data
provided by Post Office Ltd to support new facilities required by Change Request is the
Fujitsu Services Reference Data Team (RDT).

All Peak’s which need to go to Post Office Ltd will be routed (Peak term) to the RDT team
for onward transmission (in practice the largest number of Peak’s destined for Post Office Ltd
are raised by RDT).

When RDT receive a Peak to be sent onwards the Peak is routed to the appropriate Post
Office Ltd team. In Peak terms these teams are:

POCLRefDataRDO _ [issues arising from MDM system or POLRDT (Chesterfield) keying]
POCLRefDataOSG __ [issues arising from EPOSS data]

POCL-LRDP [issues arising during Live Reference Data Proving]
POCL-Test-Data [issues arising with data provided specifically for testing]

Please note that these identities were created when the Post Office Ltd name was POCL and
the teams were as described by the names. Whilst the company name and the individual team
names have changed the use of these Peak names will not be changed as they are for routing
purposes only.

Once the Peak has been routed within the Peak system itself RDT will create an e-mail and
copy in the contents of the Peak on to the e-mail. The subject line in the e-mail must contain
the word ‘Peak’ and the number of the Peak for ease of recognition.

On a periodic basis (at least monthly) RDT will provide a listing of outstanding Peak’s to all
interested parties. RDORF monitors Peak trends and Peak’s outstanding to ensure that issues
are addressed in a timely fashion.

Post Office Ltd must always explicitly respond to the Peak and not rely on the delivery of any
data to be the notification of an update to the Peak.

When RDT receive the explicit response, the Peak will be updated, in most cases by copying
the data in the e-mail into the Peak system. If the response indicates that no further action will

be undertaken by Post Office Ltd the Peak will be routed to the originating team. RDT will
advise the originator of the response that the Peak has been removed from the POCL stack.

Under some circumstances a Peak may be necessary to show that a problem has occurred but
where no further action is required from Post Office Ltd e.g. where a file has been sent to
RDMC twice. In order to record that the problem occurred RDT will create a Peak, route it
to the relevant Post Office Ltd team and immediately route it back to RDT and, in most cases,
close the Peak. A copy of the Peak will be sent to the relevant team in Post Office Ltd.

13. Appendix C — Reports and Receipts documentation

With the introduction of HNG-X the original single CCD DES/GEN/SPE/0004, which
held information on all Reports and Receipts was split into 4 parts,
DES/GEN/SPE/008 — HNG-X Branch and Counter Reports, DES/GEN/SPE/0009 —
HNG-X Receipts, Slips and Labels, DES/GEN/SPE/0010 — HNG-X Banking, Debit
Card and ETopUp Receipts and Texts and DES/GEN/0010 — HNG-X AP and ADC.
Receipts. The last two of those documents (DES/GEN/SPE0010 and
DES/GEN/SPE0011) are no longer CCD’s because the majority of changes that
occur within them are as a direct result of business as usual changes managed by
this Interface Agreement.

Because the rate of change can be very variable the documents are not always
issued for review and approval for each individual change however it is also
essential that the people who need to use them to make change have the latest
working version available to them.

The process for update will therefore be:

> for each amendment, or group of amendments to either document a new draft
version will be produced and lodged in the FJS Dimensions system. For
information purposes a copy of this version will also be circulated to an
agreed list of recipients. This will include the Post Office Reference Data
Team in Bracknell and therefore anyone in Post Office who requires visibility
of the latest version should ensure that they contact this team.

when the number of draft versions becomes excessive (e.g. 9) or no further
amendments are expected for the anticipated period required to gain sign off
of the updated document, the document will be sent out for formal review
