It’s often difficult to solicit information from a client, but documenting for developers should never be that hard.

In software engineering and systems engineering, a Functional Requirement can range from the high-level abstract statement of the sender’s necessity to detailed mathematical functional requirement specifications. Functional software requirements help you to capture the intended behaviour of the system. In this tutorial, you will learn more about:
