What Practice Area includes the practice of managing critical dependencies and activities?

The Practice Area that includes the practice of managing critical dependencies and activities is indeed Monitor and Control (MC). This area focuses on overseeing project activities and their interdependencies to ensure that everything is progressing according to plan and that any issues are quickly identified and addressed.

Effective monitoring and controlling involve tracking the status of work, managing changes to the project, and ensuring that critical activities are aligned with overall project objectives and timelines. This practice is vital for maintaining the flow of the project and meeting stakeholders' expectations.

In contrast, the other practice areas, while essential components of overall project management, address different aspects. Implementation Infrastructure (II) pertains more to the establishment of environments and structures to support project delivery, Estimating focuses on predicting project costs and durations, and Process Asset Development (PAD) involves creating and maintaining organizational assets to improve processes. These areas do not specifically center on managing the dependencies and activities critical to the success of ongoing projects.
