Performance Specifications A description of how well an artifact performs

Prescriptive Performance Specifications Range of acceptable performance Performance, not product or means of achieving that performance Stated in way that is independent of a particular solution Quantify, if possible range maximum or minimum

Examples Weight and length of ladder Loudness of radio Frequency response of audio Power radio consumes Sensitivity to rf signals How far digital indicators can be read

Interface Performance Specifications How well devices or systems must work together with other systems Physical fit with each other Electrical impedance matching Under the hood of an automobile

Detailed Design Performance Specifications After the fact, how the device actually operates after it is created
