The larger the experience of the project manager better will be his ability in identifyin g risks, estimating their occurrence likelihood and impact, and defining the mitigation and contingency plans. However, project manager risk knowledge cannot stay in an individual level, but it must be available to the organization. This paper describes an approach to risk planning in software projects based in the organizational risk knowledge reuse. A risk management process focused on the capturing and utilization of organizational knowledge together with a support c a s e tool make part of this approach. An experimental study of the relations between risk-causing facts and risks of software projects was accomplished and its results used to define such a tool.enText/Conference Paper1617-5468
