FURPS is an acronym representing a model for classifying software quality attributes (functional and non-functional requirements): * Functionality - Capability (Size & Generality of Feature Set), Reusability (Compatibility, Interoperability, Portability), Security (Safety & Exploitability) * Usability (UX) - Human Factors, Aesthetics, Consistency, Documentation, Responsiveness * Reliability - Availability (Failure Frequency (Robustness/Durability/Resilience), Failure Extent & Time-Length (Recoverability/Survivability)), Predictability (Stability), Accuracy (Frequency/Severity of Error) * Performance - Speed, Efficiency, Resource Consumption (power, ram, cache, etc.), Throughput, Capacity, Scalability * Supportability (Serviceability, Maintainability, Sustainability, Repair Speed) - Testability, Flexibility (Modifiability, Configurability, Adaptability, Extensibility, Modularity), Installability, Localizability The model, developed at Hewlett-Packard, was first publicly elaborated by Grady and Caswell. ''FURPS+'' is now widely used in the software industry. The ''+'' was later added to the model after various campaigns at HP to extend the acronym to emphasize various attributes. == See also == * Types of requirement * Expanded list of types of requirement 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「FURPS」の詳細全文を読む スポンサード リンク
