Model for Measuring benefit of government IT investment using fuzzy AHP

Abstract

Information Technology (IT) has become a mandatory for every organization including government. Investment on IT can help government to deliver services to the citizen. Every IT investment should give the maximum result. Measurement for the benefit of IT investment is needed to make sure that it has deliver the missions and goals. There are plenty models for measuring the feasibility of an IT investment before the implementation. But there are still few models to measure the IT investment after implementation. This paper proposes a model to measure the benefit of an IT investment after implementation, especially in government organizations. The model uses generic IS/IT business value category which consists of 13 categories and 73 sub-categories. Each category will be weighted according to organization preference using Fuzzy Analitic Hierarchy Process (FAHP). This model is applied to measure IT investments in the Ministry of Finance of the Republic of Indonesia, named SPAN and SAKTI applications. The weighted benefit score of SPAN is 76.39%, while the original score is 75.89%. The weighted benefit score of SAKTI is 68.08%, while the original score is 67.33%. The differences between the original score and weighted score indicate that the model accommodates the organization's preference in the evaluation.
