It is difficult to estimate the costs and benefits of mega projects because the project scope changes constantly. Accurate estimates help project managers make informed decisions about planning, resource allocation, and budgeting.

Why is it so important to have correct estimations when it comes to project management? Estimates are used to determine cash flow requirements. Estimates are used to create time-phased budgets and create a project baseline. Inaccuracies come from a lack of estimations, resulting in time and cost under/overruns.

As a result, how precise should an estimate be?

An estimate may be either verbal or written; there is no legal distinction between the two. It’s just a guess. The real price might be greater or less, but it’s usually estimated to be between 10% to 15% of the total cost. It’s a wonderful starting place for larger projects while you plan.

In the same way, which approach of cost estimation is the most accurate? Estimation using three points The mostlikelycost, pessimisticcost, and optimisticcost are the three estimations. It decreases estimating bias, risk, and uncertainty. Analogousand parametric estimation strategies are less accurate. Of all the approaches mentioned, this is the most accurate.

Why is estimating crucial in project management in this case?
