is the verification of a product or system using models, calculations and testing equipment.
Checklists give support to the reviewer, so that the result of the review is not dependent on the skills of the individual.
The four fundamental methods of verification are Inspection, Demonstration, Test, and Analysis.
To error is human, and there is no reason to think that it does not occur during the development of the system.
Problems can result from a misunderstanding between analyst and the customer an ambiguity in the documentation, etc.
However, it is wise to assume that errors will occur and establish procedures to prevent. Duration the position of the validation activity compared to the software life cycle, etc.
Why the benefits of having the requirements validation activities during the RE process?
Who are the stakeholders involved in the requirements validation process? and How the techniques and the approaches of requirements validation?
This paper will review the evolution of validation techniques and their current status in Requirements Engineering (RE).
We start by answering the following questions: What validate?
