7.4 Site Manager (SM) This is the role responsible for the day today running of one or more VTSs. The SM can carryout VTS management, and non-testing functions e.g. assign users within a VTS. Normally there will be only one SM per VTS, however, in some cases there maybe a requirement to have more than one SM listed against a VTS. Many smaller single site AEs, may well choose to assign the SM role to the AEDM, larger single site businesses may allocate it to another manager or supervisor. The decision on how many SM roles are needed and to whom they are given is left to the AEDM based on how the business is run.
