Testing Requirements

• Make the Requirement Measurable

• Quantifiable and non-Quantifiable– Requirements test 1

• Keeping track

• Coherence and Consistency– Requirements test 2– Requirements test 3

Requirement Test Questions

1. Does each Requirement have a quality measure that can be used to test whether any solution meets the requirement?
