Abstract
To support the effective introduction of IT systems, we have constructed a business justification analysis support system for IT system development. It evaluates the benefit of systems, investment effects, risk factors, and the justification of development systems. By using these information, it clarifies the appropriateness and priority level of development investment, and supports the risk management process of development phase . To clarify characteristics of projects more accuracy, we classified risk score by considering whether project managers can manage or not. By applying this technique to real projects, we considered that this risk classification technique is effective for project management.
