About Qualities of Service

Qualities of service models the idea that consumer value is generated not only by functional requirements expressed as scenarios of use, but by non-functional requirements expressed as qualities of service of operation. A quality of service mindset is fundamental to the MSF focus on delivering value. MSF for CMMI® Process Improvement elevates qualities of service to the status of customer requirements. Qualities of service can be significant product differentiators and revenue generators. Ignoring or relegating qualities of service to a product requirements role leaves a lot of potential value on the table. Everyone on the team should be conscious of the qualities of service required for the product and use them to inform design, implementation, testing, and deployment. Security, performance, and user experience are three qualities of service that are of particular concern.
