Estimating: A Comprehensive Overview
Estimating is the process of approximating or calculating the value, quantity, or cost of something for the purpose of planning and decision-making. It is crucial in various fields, including construction, finance, project management, and manufacturing, as it helps determine budgets, timelines, and resource allocation. Accurate estimating is essential for project success, as it directly impacts profitability and the ability to meet client expectations.
