VALIDATION & VERIFICATION
VaLIDATION And VaRIFICATION Testing Are Essential To Confirm That The Product We Develop Meets The Specifications And ITS Intended Use.
VAlidation TESTING – DID I MAKE THE correct product ?
Validation testing is confirmation that a product meets its intended use and the needs of its users. Following successful verification, development teams employ validation testing with the initial production product and in the actual (or simulated) use environment.
VARIFICATION TESTING – DID I MAKE THE PRODUCT CORRECTLY ?
Verification testing is used to confirm that a product meets specifications or requirements as defined in the initial stage of the product development process. Verification process is conducted iteratively throughout a product design process, ensuring that the designs perform as required by product specifications.
WHY VALIDATION AND VARIFICATION TESTING IS IMPORTANT IN PRODUCT DESIGN PROCESS ?
Validation and Verification testing play an integral part in the product development process. Creating technology and systems is an iterative cycle, in which development teams are constantly learning and feeding data back into the process.
Validation and Verification activity serve as a system of checks and balances, ensuring that developers regularly evaluate if the product is functioning as intended and meeting the needs of its users. Testing also offers an important opportunity to document the tangible results of your design efforts.
By thoughtfully and thoroughly conducting verification and validation testing, product development teams can mitigate user error and costly delays in the product’s launch schedule.
Beyond validation versus varification of a product’s design, we can also conduct “process validation” – this is an effort to confirm that the product’s manufacturing process yields outputs that comply with the product’s specifications.
BEST PRACTICES WE FOLLOW FOR EFFECTIVE AND EFFICIENT VALIDATION AND VARIFICATION TESTING
- We start early! We begin thinking about verification and validation testing efforts at the very start of the product development process. We don’t wait too long or else we may learn that the product doesn’t work as intended late in the game, creating needless cost increases and schedule delays.
- We clearly define the product’s specifications and requirements.
- We make sure that the product’s requirements are measurable. If we can’t tangibly measure or assess the product against its requirements, the requirement is ultimately not useful.
- We de-risk the test results by testing in conditions that mirror the product’s use environment sooner rather than later.
- We plan and document the validation and verification testing activity. This will really help to move a project along efficiently.
- We are creative with the testing methods!
