what is validation and verification

Answer Posted / ramyasri

Hai...

Verification:
The process of evaluating software to determine
whether the products of a given development phase satisfy
the conditions imposed at the start of that phase.
Verification is the process of determining that a
computer model, simulation, or federation of models and
simulations implementations and their associated data
accurately represents the developer's conceptual
description and specifications


Validation:
The process of evaluating software during or at
the end of the development process to determine whether it
satisfies specified requirements. In other words,
validation ensures that the product actually meets the
user's needs, and that the specifications were correct in
the first place, while verification is ensuring that the
product has been built according to the requirements and
design specifications.
Validation ensures that ‘you built the right
thing’. Verification ensures that ‘you built it right’.
Validation confirms that the product, as provided, will
fulfil its intended use.
