Introduction
In this blog, we will study how we can validate and verify the requirement that is gathered for the software product. In this chapter, we will study the characteristics of requirements and discuss a different type of requirement test that helps us to verify and validate the requirements.
What is Requirement Validation
Requirement validation is the process of confirming the completeness and correctness of the requirement. Validation also ensures the requirement.
- Clearly define the business objective.
- Clearly define the idea of the object.
- Clearly define the scope of the project.
- Verify that requirements meet the needs of customers.
- Verify that requirements are clearly understood by the developer
Objective
The objective of the validation is essential to the identification of the missing requirements and to ensure that requirements meet the quality criteria. Validation targets the individual requirement.
Characteristics of Requirement
Clear
The requirement should be clear and crystal and should not be ambiguous.
Complete
The requirement should be complete means not more and not less.
Correct
Accurately define the customer external needs
Coherent
The requirement should be coherent according to all aspects.
Valid
Validation is essential to the identification of the missing requirements and ensures that requirements meet the quality criteria
Feasible
The requirement should be feasible and implementable with known constraints
Modifiable
Can easily be changed when necessary.
Necessary
The important requirement should be documented according to customer need
Prioritized
Prioritized requirements according to rank.
Traceable
Can be linked with the system requirements and design code and testing.
Verifiable
Correct implementation of requirements can be determined by testing and analysis.
