Analyzing a CPI graph requires comparing the CPI values to the baseline plan and project objectives. It’s also important to consider the causes and effects of the CPI variations and their implications for the project scope, schedule, quality, and risk. You should ask yourself questions such as: is the CPI aligned with expectations and targets? What are the main factors that influence the CPI? How does it affect the project completion date and final cost? What corrective or preventive actions are needed to improve or maintain the CPI at a desirable level?
