FURPS is an acronym representing a model for classifying software quality attributes (requirements):

Functionality - Feature set, Capabilities, Generality, Security
Usability - Human factors, Aesthetics, Consistency, Documentation
Reliability - Frequency/severity of failure, Recoverability, Predictability, Accuracy, Mean time to failure
Performance - Speed, Efficiency, Resource consumption, Throughput, Response time
Supportability - Testability, Extensibility, Adaptability, Maintainability, Compatibility, Configurability, Serviceability, Installability, Localizability, Portability

The model, developed at Hewlett-Packard, was first publicly elaborated by Grady and Caswell. The + was later added to the model after various campaigns at HP to extend the acronym to emphasize various attributes.

FURPS+ is now widely used in the software industry.
