- In common usage, validation is the process of checking if something satisfies a certain criterion. Examples would include checking if a statement is true (validity), if an appliance works as intended, if a computer system is secure, or if computer data are compliant with an open standard. Validation implies one is able to document that a solution or process is correct or is suited for its intended use.
- In engineering or as part of a quality management system, validation confirms that the needs of an external customer or user of a product, service, or system are met. Verification is usually an internal quality process of determining compliance with a regulation, standard, or specification. An easy way of recalling the difference between validation and verification is that validation is ensuring "you built the right product" and verification is ensuring "you built the product as intended." Validation is confirming that it satisfies stakeholder's or user's needs.
- Validation can mean to declare or make legally valid or to prove valid or confirm the validity of data, information, or processes:
- In computer terminology, validation refers to the process of data validation, ensuring that data inserted into an application satisfies pre-determined formats or complies with stated length and character requirements and other defined input criteria. It may also ensure that only data that is either true or real can be entered into a database.
