In this lesson we will learn about software validation and verification, an aspect of project management in which requirements and processes of new software are analyzed to verify that the product meets certain specifications and functions correctly. A county library staff currently records all library transactions on a hand-written ledger - everything from lending materials to recording fine payments.
They would like to automate these manual processes through the use of a computerized system.
The plan analyzes in detail what the functions of the software would be, how it would interact with existing systems and what the user interfaces would look like.
For example, the head librarian requests that the new software provide a user-friendly interface with a large font so that searching the library catalog is quick and the results are easy to read.
System Validation is a set of actions used to check the compliance of any element (a system element, a system, a document, a service, a task, a system requirement, etc.) with its purpose and functions.
These actions are planned and carried out throughout the life cycle of the system.
Validation is a generic term that needs to be instantiated within the context it occurs.
When understood as a process, validation is a transverse activity to every life cycle stage of the system.
Validation is the process of evaluating the final product to check whether the software meets the business needs.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?It is important to remember that while system validation is separate from verification, the activities are complementary and intended to be performed in conjunction.Validation is the confirmation, through the provision of objective evidence, that the requirements for a specific intended use or application have been fulfilled.
When we carry out the V&V tasks, we have to concentrate both of these view of quality.
