Verification and validation are independent procedures that are used together for checking that a product, service, or system meets requirements and specifications and that it fulfills its intended purpose.
In practice, the usage of these terms varies. Sometimes they are even used interchangeably. The assurance that a product, service, or system meets the needs of the customer and other identified stakeholders. It often involves acceptance and suitability with external customers.

ISO standard accredited company for a particular division, the process is called certification. If any critical data is missing, then the work can not be processed or can only be completed partially. The most important and significant effects are tested.
From an analytical chemistry perspective, those effects are selectivity, accuracy, repeatability, linearity and its range. To solve this kind of difficulties, some regulatory bodies or compendial methods usually provide the advices on what the circumstances or conditions that the performing of a specified system suitability test should be applied and compulsory. These terms generally apply broadly across industries and institutions. In addition, they may have very specific meanings and requirements for specific products, regulations, and industries.
