There are, but I don’t have a problem with fujitsu writing it ~ we will oversee it. They are the technical experts so it feels
appropriate if it is of a technical nature

Strictly Private and Confidential - Subject to Legal Privilege
Simon,
Is there no one in-house with knowledge of Horizon requirements? Should we be handing responsibility for
this to a supplier firm without overseeing it ourselves?

Do you want to call Gareth and ask if he wants to lead on this one?

l have had a discussion with Andy and I think we may want to consider if there is a need for someone from an iT
background to lead this SR. We would need to ensure they have knowledge of the design and operational requirements
with respect to power outage and what the branches are instructed to do in a recovery position.
Andy could lead on this but most of the input would be coming from elsewhere and maybe someone involved in the
Horizon and Horizon on line design within the business would in a better position to provide the factual information.
With respect to the comments about P&BA, Andy is in the best position to respond to how we handled this dispute.
Kind Regards Alison

Further to Simon’s email below:
1. Andy, will you take the lead again please on the draft response with input from Gareth (words and
flowchart) on Horizon operational design for power and comms failures. How long will you require for
first draft (given Easter coming up) so I can make a note on the Tracker?
2. Who is best placed to enable and facilitate the Horizon testing requested by Second Sight? I suggest
we need suitable access to a Horizon terminal but I also think we ought to ask for a test plan so we can
see the number and type of tests to be done to ensure a) the approach is robust (from a system testing
point of view) and b) the environment is correctly configured and support to enable the testing.

This is a general catch up on a number of issues:
1. attach Spot Review SRO01.docx which is the John Armstrong case we discussed on the last call
2. The main issue in SROO1 is the automated and largely silent recovery process which occurs when Horizon detects
either a power or a communications failure. Can you ask Fujitsu to provide us with a clear written description,
including flowcharts, of how this is designed to operate for both old and new Horizon?
3. Tied in to the above, we would like to run some tests on a live Horizon terminal (possibly a training terminal)
when we execute various types of transaction and at the same time cut the power or the internet connection.
We will then observe and analyse the recovery process. It will be important that the terminal being used is a
close to a live system as is possible. I assume the training office terminal in your building will be the best place to
do this, however we will probably need to book this for a number of sessions. Will this be possible?
Many thanks. I look forward to seeing you on Thursday afternoon
With best wishes
