The estimation is important because it gives the project team some confidence about the required effort and time to plan ahead for the project.

The estimation is a process to find the most accurate sizing figure for the software project effort, for example, how many months you will need to develop the software, how many resources you will need to finish the project in the required time. What is Estimation and why it is important?

In this article, I will illustrate how to easily estimate the software effort using known estimation techniques which are Function Points Analysis (FPA) and Constructive Cost Model (COCOMO).

The software development effort estimation is an essential activity before any software project initiation.
