When a project experiences consistent deviations in cost performance index (CPI) and schedule performance index (SPI), it indicates underlying issues with the project ' s assumptions regarding schedule and resources. Analyzing these assumptions helps identify discrepancies between planned and actual performance, such as underestimated task durations or insufficient resource allocation. By revisiting and adjusting these assumptions, the risk manager can develop strategies to mitigate further overruns and align the project with its objectives.
