What Is Parametric Estimating?

Parametric estimating uses a statistical relationship between historical data and other variables (e.g., square footage in construction) to calculate an estimate for activity parameters, such as cost, budget, and duration.

What is parametric cost estimating?

Parametric cost estimating is a parametric technique that uses regression or other statistical methods to develop Cost Estimating Relationships (CERs). A CER is an equation used to estimate a given cost element using an established relationship with one or more independent variables.

What is the importance of parametric estimating?

Parametric estimating is the task of looking at past projects to get a good estimate of how long a current project will take and how much it will cost. It also allows you to measure individual tasks within the project to get a more accurate cost and time frame.
