A service portfolio is more than just a list of services. It describes all the planned services offered by a service provider, as well as those in the development phase plus current services in terms of their benefits for the business. The service portfolio management is used to control and manage all investments in the service management, making the service portfolio a central component of the IT governance. The development of a structured service portfolio management enables questions to be answered with regard to service benefits, quality and price structure as well as strengths, weaknesses and risks of the IT services offered.
