Impact Analysis
Every product or system goes through evolutionary process, this happens due to various reasons naturally, customer request, innovation, market pressure. When systems change, it becomes necessary to analyze the change. Ecosystem offers Impact Map which helps in understanding the links in the system in both upstream and downstream direction. Traceability tags used conventionally across system engineering documents when linked properly allow to construct the impact map. This helps determine that if the use case, requirement, design change is desired which parts will require an update. This helps to visualize, discuss and estimate the cost of change.
Depending on Impact Analysis the Change Control Board may decide whether to allow changes now or defer it to the future and if this is a client project, perhaps a negotiation will follow.
