The project manager should mitigate risks identified on the sensitivity analysis to ensure the P90 date is met.
Sensitivity analysis helps identify the most critical risks that have the potential to impact the project's completion date. By mitigating these risks, the project manager can increase the likelihood of meeting the P90 date.
According to the PMI Risk Management Professional (PMI-RMP) Reference Materials, the P90 date is the date that has a 90% probability of being met or exceeded by the project completion1. The Monte Carlo analysis is a simulation technique that generates possible outcomes of the project schedule based on the probability distributions of the activity durations2. The sensitivity analysis is a technique that determines how different sources of uncertainty affect the project objectives, such as the completion date3. Therefore, the project manager should mitigate the risks identified on the sensitivity analysis, as they are the most likely to affect the P90 date. By reducing the uncertainty and variability of the project schedule, the project manager can increase the confidence level of meeting the P90 date.
