The project manager should review the communications management plan and communicate which technology is to be used to develop, transmit, and store project artifacts. This is because the communications management plan is a document that outlines the communication expectations and standards for the entire project. It includes the technologies to be used for communication, the frequency of communication, the persons responsible for communication, and the methods of communication12. In this case, the project manager was not aware of the task status because the developer used a specific project management software that was not communicated or agreed upon in the communications management plan. Therefore, it's important for the project manager to review and communicate the agreed-upon technologies for project communication to avoid such issues in the future12. References:
