FURPS (Functionality, Usability, Reliability, Performance, Supportability)

FURPS is a framework used to evaluate software quality across five key areas. Functionality refers to what the software does and if it meets user needs. Usability assesses how easy and comfortable it is for users to operate the software. Reliability measures the software’s stability and consistency over time. Performance looks at how quickly and efficiently the software responds under different conditions. Supportability considers how easy it is to maintain, repair, or update the software in the future. Together, FURPS helps ensure software is effective, user-friendly, dependable, efficient, and maintainable.
