Various embodiments provide one or more of systems, methods, software, and data structures rate risk of proposed system changes. Some embodiments include receiving input representative of answers to a set of system change questions presented to a user and the answers representative of a proposed system change. A risk ranking of the proposed system change may then be derived based on the received system change question answers and a success factor will be identified based on the historical data. Further, a probability factor weightage indicative of an amount of data considered in identifying the success factor may be obtained. A risk rating is then calculated for making the proposed system change based on the risk ranking, success factor, and probability factor aspects of the proposed change, which helps in better change management.
