A Method of IT Service Portfolio Selection Based on BDIM
This paper presents an approach to define the IT service portfolio so that the definition can bring the best interests to the IT Service provider and its customers. During the Service Strategy phase of the IT service life cycle defined in ITIL, the major challenge to be faced by IT executives is the selection of a maximum benefits IT service portfolio. In this paper, the IT service portfolios are mainly evaluated in two ways, which are the value that the customer can receive from it and the analysis of the potential financial impact from the SLA-dependent group. There is uncertainty in the above estimate, which is taken into account by means of utility theory and interval arithmetic. The outcome of the approach helps the service provider easily define the IT service portfolio.
