Analyzing Cost and Schedule Variances in the Performance Measurement Baseline
When the performance measurement baseline (PMB) data reveals a cost and schedule variance exceeding 25% between planned and actual figures, several factors could contribute to such deviations. It is essential to analyze the root causes behind these variances before drawing conclusions about the estimate accuracy, program team effectiveness, or the presence of significant contingencies post PMB development.
Thesis Statement:
A cost and schedule variance of more than 25% in the performance measurement baseline data does not necessarily indicate a single cause; rather, it may result from a combination of inaccurate estimates, ineffective program management, and unforeseen contingencies.
Possible Scenarios:
1. Estimate Accuracy:
– If the variance is primarily due to inaccuracies in the initial estimates, it could signify that the planning phase did not adequately account for all project complexities or risks. Revisiting the estimation process and conducting a detailed analysis of the assumptions made during planning is crucial in such cases.
2. Program Team Effectiveness:
– In scenarios where the program team is not effectively managing the project, variances could arise from poor resource allocation, lack of communication, or inadequate risk mitigation strategies. Addressing issues related to team coordination, leadership, and stakeholder engagement is essential to improve program performance.
3. Significant Contingencies:
– The presence of significant contingencies post PMB development can also lead
