System Requirements and Functional Requirememts


Can you please explain me the difference between system and functional requirements?

In the company that I working for , I perform a business analyst / design role for one of the applications that is responsible for fulfulling and provisioning a service requested by the customer. My deliverable is a design document that comprises of system requirements and functional requirements. We define system requirements to define high level capabilities of the system and define the functional requirements to break down the system requirements into sufficient detail. So an SR can contain 1-N FRs. I was not sure if it is something that is followed across the industry


Solution

  • In software engineering functional requirements describe what software is supposed to do. System requirements describe what hardware/OS/middleware software should be run on.
