Design Quality
Design quality is the value of a design such as a product design to users. For example, a volume dial on a speaker that moves with a pleasing level of resistance without being too stiff or loose feeling.Build Quality
Build quality is the overall workmanship and materials quality of an item. For example, a speaker with a fine satin finish that is free of defects, color issues or smells.Reliability
Enduring and consistent performance in real world conditions. For example, a drum designed to maintain its sound for at least 150,000 strikes.Consistency
The requirement that units be the same or that units be internally consistent. For example, apples that are mostly the same size with similar appearance and taste.Availability
The availability of a service. For example, a requirement for a software service to be up 99.99% of the time.Usability
Requirements related to ease of use such as a can of coffee that is easy for everyone to open and reseal.Customer Experience
Requirements that make a product or service more pleasing to customers. For example, the requirement that coffee smell good when you first open the can.Look & Feel
