What Practice Area is focused on estimating the amount of work required?

The Practice Area focused on estimating the amount of work required is indeed Estimating. This area specifically addresses the processes and techniques used to estimate costs, resources, and time needed to complete a project successfully. In project management, accurate estimates are crucial for planning and executing tasks efficiently.

Estimating involves several methodologies and tools that allow teams to gauge the scope of work before project initiation, enabling better decision-making and resource allocation. By focusing on estimating, organizations can enhance their forecasting abilities, reduce uncertainties in project outcomes, and improve overall project performance.

The other options, while related to project execution, address different aspects. Project Management encompasses the broader discipline of planning, executing, and closing projects. Work Breakdown Structure is primarily a technique used to define the total scope of the project by breaking it down into manageable parts, but estimating is a distinct section of this process. Risk Management deals with identifying, assessing, and mitigating risks rather than estimating work effort specifically. Therefore, the emphasis on estimating work clearly aligns with the correct answer.
