When a project manager receives a request to add features and functions after the project scope has been established, it is essential to follow the change management process. This process involves several steps, including identifying the change request, conducting an impact analysis, documenting the change, presenting it to the Change Control Board (CCB), making a decision on the change, communicating the decision to stakeholders, and implementing approved changes. The change management process ensures that any modifications to the project are controlled and aligned with project objectives, minimizing risks and disruptions1.

Agile project management emphasizes the delivery of value to the client in small, incremental stages rather than waiting until the end of the project. This approach allows for more flexibility and adaptability, as changes can be made more easily in response to feedback from the client or changes in the project environment. Therefore, the new project manager should meet with the team to review the backlog and create small iterations that can deliver incremental value to the client.

In a matrix organization where a large number of stakeholders are involved, it is crucial to have an efficient communication plan that ensures information is disseminated effectively without overwhelming the stakeholders with direct communication. Setting up an intranet site allows stakeholders to pull information as needed, which aligns with the best practices for communication in project management. This approach is supported by the PMBOKGuide, which suggests using pull communication methods for large volumes of information, where stakeholders can access the information at their own convenience. It also aligns with the Professional in Business Analysis (PBA) best practices, which emphasize the importance of having a clear communication plan that defines how information will be shared and ensuring that communications reach the right audience.
