What is the relationship between the Estimating (EST) Practice Area and another Practice Area?

The Estimating (EST) Practice Area has a close relationship with the Planning Practice Area because effective project planning heavily relies on accurate estimates of time, resources, and costs. Estimation involves gathering data, analyzing previous projects, and applying methods that help project managers and teams forecast what is necessary to complete the work successfully. This information feeds into planning activities, where schedules, resource allocations, and budgets are developed based on the estimates provided.

An effective planning process integrates estimates to ensure that there is a realistic and achievable project trajectory. Without well-grounded estimates, planning can become speculative and less reliable, potentially leading to project failures due to unforeseen difficulties or resource shortages. By coordinating the estimating efforts with planning, organizations can increase their chances of project success, aligning expectations with actual capabilities and resources. This correlation highlights the importance of the EST Practice Area in the broader context of project management within the CMMI framework.
