Use historical data from similar past projects to estimate the duration or cost of the current project

It is a rough estimating method that is often used to estimate project duration in the early stages of a project when detailed information is insufficient.

Low cost, fast, poor accuracy

Key points: Essential similarity, not superficial similarity; the estimating team members are very professional

An estimating technique that uses an algorithm to calculate cost or duration based on historical data and project parameters.

Use statistical relationships between historical data and other variables to estimate, such as: duration = total amount of work/average daily workload

Accuracy depends on the maturity of the parameter model and the reliability of the underlying data
