Explanation
According to the PMBOK Guide 7th Edition, the project manager should monitor and control project work and respond to any issues or risks that may affect the project performance. In this case, the project manager should conduct an impact analysis to assess the effect of the scope changes and the delay on the project objectives, scope, schedule, cost, quality, and other factors. The project manager should also present the results of the impact analysis to the steering committee, which is a group of senior stakeholders who provide guidance and oversight to the project, and seek their approval for any changes12.
