FURPS+ Model

The FURPS+ Model primarily addresses friction related to software implementation and delivery. By categorizing system requirements, it aims to improve the quality of the software, and potentially enhance the customer experience.

The FURPS+ Model, developed by Robert Grady at Hewlett-Packard, is a comprehensive classification system for software quality attributes. It stands for Functionality, Usability, Reliability, Performance, and Supportability, with the '+' signifying additional considerations like design constraints, implementation requirements, interface requirements, and physical requirements. This framework helps in setting clear expectations and benchmarks for software development projects, ensuring all critical aspects of system performance and maintenance are addressed.
