I'm writing some documentation in a project in a tool. In this tool of mine, and write in specific area, I have here use Case, Business Rule, N-Diagram Types, and Functionality and Functional Requirements.

So I got me wondering, Are there differences between Functionality and Functional Requirements?

In my vision, a Functionality a implementation of a Functional Requirement, is it correct? What other differences one can find between them?

There are either too many possible answers, or good answers would be too long for this format. Please add details to narrow the answer set or to isolate an issue that can be answered in a few paragraphs.If this question can be reworded to fit the rules in the help center, please edit the question.

As far as I know, Functionality and Functional Requirement are synonyms in this context. – Philipp Jan 9 '13 at 19:42
Here's clarification based on my deduction on my way to work this morning; I believe things need to BE functional. ... things need to HAVE funtionality . Let me know if you disagree. – user127222 Apr 17 '14 at 12:38

Functionality is what a program does.

Functional requirements are what you want the program to do.
