The term functional relates to the way something works or operates. Non-functional relates to the quality and resilience of something. The following are illustrative examples.


A product function is how a product satisfies customer needs. Non-functional aspects of a product define its quality. For example, a bicycle may have a bell that functions as a safety device to make your presence known to pedestrians and other bicyclists. Non-functional aspects of a bicycle include the durability of its tires such as tires likely to last 5,000 miles.
