Requirement #1: Functionality

First and foremost software is about functionality. That's what customers mainly want: software that functions, that works, that processes data in a certain way. Functionality is the most important of the RequirementCategories.

Software has high functional quality if it transforms data as needed and expected by a user. Calculating, formatting, storing, retrieving, filtering, displaying data are examples of functionality. Functionality is about what software does.

Functionality is one aspect of a software's runtime Behaviour and is implemented using Logic.

As long as functionality is missing customers tend to prioritise it higher than requirements in other categories.
