An updated earned value report shows: Budget at Completion = US$1,000,000; Earned Value = US$700,000; Actual Cost = US$750,000; CPI = 0.933. Based on this information, what should the project manager conclude about project performance?

The correct answer is "The project will be difficult to complete as planned." The Cost Performance Index (CPI) is 0.933, which is less than 1.0. A CPI less than 1.0 indicates that the project is over budget for the work completed. This means that for every dollar planned to be spent, only $0.933 worth of work has been accomplished. This financial inefficiency suggests that completing the remaining work within the original budget and schedule will be challenging. "The project will be completed exactly as planned" is incorrect because a CPI of 0.933 shows a deviation from planned cost performance. "The project will be easier to complete than planned" is incorrect; a CPI less than 1.0 indicates cost overruns, making completion harder, not easier. "The project will not be completed as planned" is too definitive; while challenging, completion is still possible, but it will likely require adjustments to scope, schedule, or budget.
