What is the estimation technique in project management?

Project estimation techniques is a method of finding a rough approximation, to a project that is an identified value to solve a problem with having data that is uncertain, incomplete, or unstable. It is used to calculate some of the parameters such as cost, efforts, time, and resources to do a project.
