4 Exit Reform Phase 1 Plan

5 User Trials - Purpose The purpose of User Trials is: To allow Users to undertake business process activities introduced by Modification 0195AV and which are to be delivered in the new NTS Exit Reform system (replacing the 2009 interim process). This will allow users to gain a greater understanding of the steps required to manage their capacity profiles. To allow Users the opportunity to familiarise themselves with the new NTS Exit Reform system. To allow Users the opportunity to highlight any potential faults found prior to the system implementation. To provide xoserve with further assurance that external connection to the solution works as expected and previously tested.

9 User Trials - Training The new NTS Exit Reform system is based on the existing Gemini system, in particular the Entry Capacity processes, which Users will already be familiar with. Users will also have completed the new Exit processes as part of the 2009 Off-line process. Hence it is believed that refresher training will be sufficient. The planned Training is to cover the processes that will be executed as part of the User Trials and is expected to take place w/c 22 nd March Three options have been identified with regards to the delivery method: a) Classroom based training (at 31 Homer Road, Solihull or other agreed location). b) Remote training (via Live Meeting). c) Self study The Training materials will be developed in response to the chosen option. It has been recognised that some users will be new to the Gemini system. Therefore a familiarisation presentation will be made available. This gives an introduction to the layout of the system, menus etc. Q. Is there a preference as to how the Training will be delivered?

10 User Trials – Connectivity Testing User Trials will be executed in a dedicated environment that will mirror the production system. In order to access this environment each participant will need to be granted access. It is envisaged that participants will execute User Trials from their workplace therefore Connectivity Testing is planned to ensure there are no issues accessing the environment ahead of User Trials commencing. Part A Scheduled for w/c 15 th March Participants are expected to log on via Citrix. A Set up document will be provided that details instructions on how to do this. If successful, each participant will be able to reach a screen displaying the Gemini icon. Part B Scheduled for w/c 29th March Participants are expected to log on via Citrix and then access the system. The Set up document also details instructions on how to do this. If successful, each participant will be able to log on via Citrix, click on the Gemini icon, reach the Gemini log on screen where they then enter their unique username and password. This will take the user to a screen with two options – one to enter the current Gemini system and one to enter the new NTS Exit Reform system. By selecting the NTS Exit Reform option they will be able to enter the new system. Please note during User Trials the Gemini database will not be accessible.

11 User Trials - Data The User Trials environment will be refreshed with production data. In addition to this the data from the NTS Exit 2009 Offline process will be migrated into the environment. The data to be loaded by Users as part of User Trials will be provided by xoserve and provided to each user along with the associated expected results.

12 User Trials – Execution The execution of User Trials is scheduled for w/c 5 th April 2010 (please note the 5 th April is a Bank Holiday). High level schedule: Day 1Tuesday 6 th April1) Submit requests for Enduring annual NTS Exit Flat Capacity Application 2) DN adjustments (DNs only) Day 2Wednesday 7 th AprilCapacity Allocations Day 3Thursday 8 th AprilPublication of results & reports verification Day 4Friday 9 th AprilContingency day Day 5Monday 12 th AprilSubmit Requests for Enduring Ad hoc NTS Exit Flat Capacity Increase Application Day 6Tuesday 13 th AprilCapacity Allocation Day 7Wednesday 14 th AprilAccept/Reject Adhoc Offers Day 8Thursday 15 th AprilPublication of results & reports verification Day 9Friday 16 th AprilContingency day Based on the above schedule User activities are planned for Days 1, 3, 5 and 8. Any changes that are necessary to the schedule will be communicated. The system will be available for the duration of User Trials, however, we request that data is only input as per the schedule.

13 User Trials – Execution In advance of this each participant will be provided with the following: a) User Trials Guidelines b) User Trials Schedule c) User Trials Scenarios d) User Trials Instructions Due to the limited time available we recommend that activities are executed in the morning. This will ensure maximum time is made available and should anyone experience any difficulties there will be more time available to resolve these. During User Trials the project team will provide technical and process support and will be in regular contact with participants.

14 User Trials - Communications Further teleconferences are planned so that all parties can be updated on progress. Monday 1 st March 2010 – Progress t-con Monday 15 th March 2010 – Progress t-con Monday 29 th March 2010 – User Trials Kick off t-con In addition to the above a short t-con will be arranged for each day during the execution of User Trials.
