Question

After the elicitation process and gathering all the customer requirements, what are the
requirement validating techniques that you would use to demonstrate that the
requirements define the system that the customer really wants?

Answer 1

SOLUTION:- Requirements validation techniques that we would use to demonstrate that the requirements define the system that the customer really wants are given below:-

(1) Requirements reviews : We will perform systematic manual analysis of the requirements.
(2) Prototyping : Utilizing an executable model of the system in order to check requirements.
(3) Test-case generation : Developing tests for requirements in order to check testability.

We will apply the following checks during requirements validation :

(1) Validity checks, consistency checks, completeness tests, realism checks, the verifiability of requirements.
(2) Belonging with demonstration that the requirements define the system that the customer really wants.
(3) Requirements error costs are exalted so validation is very crucial such as fixing a requirements error after delivery can cost up to 100 times the cost of fixing an implementation error.
