Risk control and implementation planning in IS project

The cost and benefit of information system project are uncertain which brings high risk. Therefore, in order to carry out project planning under the pre-condition of controlling risk, it is important to identify the risk features of IS project. As a first step towards that goal, this article discusses the stochastic variations of cost and benefit of IS project and elaborates the mathematical description of them. Additionally, the risk-control model of IS project under uncertainty is built by applying dynamic programming. Finally, a project planning method considering appropriate risk-control with the time and cost limitation is proposed using integer programming method, whose feasibility and efficiency are validated by case study.
