Abstract:
IT governance lacks a comprehensive vision of investment in two or more projects. It is necessary to decide the priority levels that maximize the effects under constrained conditions. It is a complex problem, because while sometimes a greater effect can be obtained by introducing two or more measures at the same time, other times the effect of two measures introduced at the same time might not be significant. Although there is a synergy effect when two or more measures are introduced, no method for drawing up an investment-decision road map has considered that effect. Therefore, we developed one. What a decision-maker must think about when considering the introduction of two or more measures, can be visualized by drawing up a comprehensive road map that satisfies constraint conditions, such as the effectiveness of the measure, budget, time, staff size, order of introduction, and the synergy effect. Road map users can easily reach a consensus because the map, by taking into account th
e constraint conditions and the investment decision-making process, helps them logically explain the order in which the measures should be introduced.
