The team leader is responsible for managing the work of the team. He is also responsible for monitoring new technologies that are relevant to the work of the team with a view to evolving the technologies used by the team when and where appropriate. Any change to the technology used should be proposed to CEG in the form of a paper covering the options considered, their pros and cons and the proposed choice of technology.
Teams should disseminate information about work done by the team to the other computing staff. This could be done by providing minutes of team meetings (as long as the latter described the work done since the last team meeting) and announcing the publication of the minutes as soon as they become available.
Services should ideally be run on hardware for which there is at least one spare equivalent unit so that realistic testing and training can more easily be arranged using the spare equipment. In particular hardware for servers should normally be chosen from a limited set of agreed hardware platform configurations.
In choosing a hardware platform for a server teams should avoid all single points of failure wherever this is reasonable. The extent to which all single points of failure are removed depends on cost and criticality of the service. Things to consider are:
Before any new or significantly changed service is introduced by a service team they must ensure that the service is adequately documented. The documentation should be produced with the active involvement of the Front Line user support team and it should be signed off by them before the service goes live.
