Abstract

Finding a satisfactory vendor or outsourcer for IT projects is a tedious task in typical public organizations. When there are many alternatives, it may be difficult to choose the right one. Thus, many selection criteria need to be used. In this paper, we present an MIS system that provides supported information for selecting the vendors. First, a standard specification is given to the system. Also, the scoring criteria is defined for each feature in the specification. Then, the vendors propose their product specification to the system. The system gives the summary reports comparing each vendor product and how much the criteria is met. Hence, the user can decide which vendor to choose. We present a case study of three scoring approaches, namely Percentage of Weight, Percentage of Price and Total Percentage, in one of a public organization.
