Since the purpose of a PMO is to overcome the problems an organisation has in consistently achieving success from its projects and programmes, it is those problems that should define the balance of the role. This in turn should determine the functions it performs or the services it provides. The nature of those services should then define the type of staff required. But it appears that in many cases the role is actually determined by the skills and experience of the PMO staff and the services they are able to provide. .
