Fit criteria for Non-Functional requirements

A non-functional requirement is a quality that the product must have to do,and fit criteria is a measure of a non-functional requirements. One can measure if the user likes the product or not by doing the surveys for that product before and after introducing it. The requirements are supposed to measure because if they cannot be measured then are not requirements anymore.

By analyzing the measurements, the requirements become ambiguous, fully formed and testable from vague. To measure the requirements one should keep on discovering them and try to get stakeholder’s intentions.

    Fit criteria needs some proper amount which specifies the measurement.
    For example, Bell MTS shall sort channels within 10 seconds.

    Deriving the Fit Criteria is not a simple task. It becomes very hard to determine the scale of measurement which basically means unit of the measurement. For example, loudness of sound is measured in decibels and amount of light is measured in units in lumens.

    Fit criteria is neither a test nor the design for a test, but rather a benchmark that the delivered the product has to be tested against. It is used as an input to build a test case to ensure that the products complies their requirements.

    For example, If the requirement for a milk container is a suitable size. It is obviously impossible to test any delivered solution. By contrast, it the requirement says shall be 14 centimeters in height and 8 centimeters width. So, it will be a sample way to test the product.
