Which Practice Area is concerned with estimating the amount of work required?

The Practice Area focused on estimating the amount of work required is indeed Estimating. This area is essential in project management as it involves determining the resources, time, and effort necessary to complete tasks and projects successfully.

In the context of CMMI, effective estimation plays a critical role in planning and managing projects. It aids in setting realistic expectations for stakeholders and provides a foundation for tracking progress throughout the project lifecycle. The Estimating practice area encompasses techniques, tools, and methodologies used to produce accurate and reliable estimates, which help teams allocate their efforts efficiently and mitigate risks.

Process management relates more broadly to the frameworks and procedures that ensure project work is conducted effectively, but it does not specifically address the estimation of work required. Quality risk analysis focuses on identifying and mitigating risks related to quality, which is another crucial aspect of project management but not directly tied to estimating work. Requirements management deals with gathering and managing stakeholder needs and project requirements, serving a different purpose in the project lifecycle. Thus, Estimating stands out as the most relevant choice regarding the assessment of the work required for projects.
