Which Practice Area includes the practice of developing high-level estimates?

The practice of developing high-level estimates falls under the Estimating Practice Area. This area focuses specifically on the processes and techniques used to create estimates for time, cost, and resources necessary to complete projects and deliver products successfully. High-level estimates are critical for early project planning, enabling stakeholders to make informed decisions regarding project feasibility, resource allocation, and scheduling.

Estimating is essential within project management as it lays the groundwork for project planning and execution. This practice involves identifying the scope of work and using historical data, expert judgment, and various estimation techniques to derive estimates that guide project leaders and teams throughout the lifecycle of the project.

The other practice areas do not specifically address the development of estimates. Process management relates to defining and refining processes; implementation infrastructure focuses on the systems and tools that support process execution; and process asset development revolves around creating and maintaining organizational process assets. While these areas are essential for organizational effectiveness and project management, they do not emphasize the specific practice of creating high-level estimates as the Estimating Practice Area does.
