phase estimating method

Explanation:

The approach to estimating project time and cost that begins with an overall estimate for the project and then refines estimates for various stages of the project as it is implemented is known as PHASE ESTIMATING METHOD

The above statement is based on the fact that PHASE ESTIMATING METHOD is applicable whereby the total estimate of a product life cycle is extremely difficult to ascertain.

Instead, to get the estimate, each elemental stage is estimated one after the other, with the immediate stage having an elaborate estimate, while the subsequent stages having a brief or overview estimate.
