A project manager diligently measured progress of a project by taking many performance measurements. These measures were promptly documented and filed away. The project went over budget and behind schedule, which came as a surprise to key stakeholders. However, the project manager showed them the performance measures that were taken, so this shouldn't have been a surprise to anyone. What advice would you give to this project manager? A. The project manager should have reached out to the team earlier to discuss ways of improving their performance. B. The project manager should have saved these files in a more accessible location so that all the key stakeholders could have had visibility to the status. C. These measures should have been communicated to key stakeholders as they became available. D. The key stakeholders should have been more involved in decision-making during the project.
