what is verification and validation?..

Answer / tushar, pune

Verification is the process of determining if a system meets
the conditions set forth at the beginning, or during
previous activities of the software development life cycle,
correctly. These conditions are set forth in software
requirements, which are usually formally documented. The
standard for software requirements documentation is
ANSI/IEEE Standard 830. Verification typically involves
reviews and meetings to evaluate
documents,plans,code,requirements and specifications. This
can be done with checklists, issues lists, walkthroughs, and
inspection meetings.

Validation is the process of evaluating a system to
determine whether it satisfies the specified requirements
and meets customer needs. Validation typically involves
actual testing and takes place after verifications are completed

Validation
-----------
1) Am I building the right product

and is performed at the end of the project.

required to satisfy the requirement)
4) High level activity
5) Performed after a work product is produced against
established criteria ensuring that the product integrates
correctly into the environment
6) Determination of correctness of the final software
product by a development project with respect to the user
needs and requirements

Verification
------------
1) Am I building the product right
2) The review of interim work steps and interim
deliverables during a project to ensure they are
acceptable. To determine if the system is consistent,
adheres to standards, uses reliable techniques and prudent
practices, and performs the selected functions in the
correct manner.
3) Am I accessing the data right (in the right place; in
the right way).
4) Low level activity
5) Performed during development on key artifacts, like
walkthroughs, reviews and inspections, mentor feedback,
training, checklists and standards
6) Demonstration of consistency, completeness, and
correctness of the software at each stage and between each
stage of the development life cycle.
