* Verification - Are we doing the thing right? (Efficiency)

* Validation - Are we doint the right thing? (Effectiveness)

Verification ensures that you are building a product according to its requirements, specifications, and standards. For Verification, you should ask the following questions:

* Are you meeting the specified requirements?
* Are you building the product right?

Validation ensures that your product will be usable once it is in the marketplace. For Validation, you should ask the following questions:

* Are you meeting the operational need?
* Does this product meet its intended use in the intended environment?
* Are you building the right product?

Verification:It is the process used to check the completeness of the documents.Verification Techniques are reviews,walkthru's & Inspection.

In general we use Verification Techniques on documents like FRS,Application design documents,Test plan documents,Test case documents.

Validation: It is the process used for checking Correctness of the program or applications.Validation Techniques are Unit Testing,Integration Testing

Verification is a process to ensure that the software that is made matches the original design. It checks whether the software is made according to the criteria and specification described in the requirement document.

Validation: Means are we doing things right.i.e we have to check whether we have developed a software as per the client requirement.

Verification ensures the product is designed to deliver all functionality to the customer; it 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. You CAN learn to do verification, with little or no outside help. Get CAN get free information. Click on a link!
Validation ensures that functionality, as defined in requirements, is the intended behavior of the product; validation typically involves actual testing and takes place after verifications are completed.
