Chapter - 12 Fit Criteria and Rationale

 Fit Criteria and Rationale

Fit Criteria : 

"Fit" means implies an answer totally fulfills or matches the business requirement and "Criteria" means a principle by which someone may be judged. The fit criteria is effectively implemented as a result. It is important because it  exhibits how estimating a prerequisite make it reasonable and testable.

Why does fit need a criteria : 

1. It needs a benchmark as an analyzer.

2.  "The idea is for each requirement to have a quality measure that makes it possible to divide all solutions to the requirement into two classes: those for which we agree that they fit the requirement and those for which we agree that they do not fit the requirement."

3. At the point when a business requirement for the item is to complete some capacity, the testing activity of the work must demonstrate the product plays out that function.

Scale of Measurement :

The scale of measurement is a classification that describes the nature of the information within the values assigned to variables. It is hardest part of the testing process.

Application of fit criteria :

A fit measure can be utilized as a target test for whether the arrangement is an adequate method for fulfilling the necessity. Fit criteria create a final answer in yes or no. Fit criteria is a real business requirement. We can drive a fit criteria by examining the requirement's rational, description and figure out which measurement best communicates the client's exception fro the necessity.

* Use 'must' for critical requirements and 'should' for non-critical requirements
