This research study focused on an improved decision support system for software evaluation using weighted sum. Given the increase in the number of software packages in the market today, there is a challenge of knowing which is most effective to solve the problems of an organization without creating problems. It is in view of the need to select the most appropriate software among alternatives that gave rise to the concept of software evaluation. Software evaluation is the process of assessing the quality of different software systems so as to choose the most productive one. Evaluating and selecting software packages that meet an organization’s requirements is a difficult software engineering process. Selection of a wrong software package can turn out to be costly and adversely affect business processes. One of the most common techniques used for evaluating software components is weighted sum. In this technique, the criteria for evaluating the software are clearly defined and values are assigned as weight to each criterion. The total of the weight placed on each criterion reveals the level of effectiveness of the software component. For the scope of this study, the evaluation is carried out under three different criteria categories which are; vendor, hardware/software requirements and cost/benefits.
