Validointiperiaatteet (Validation Principles) refer to a set of guidelines and standards used to ensure that a process, system, or product consistently achieves its intended purpose and meets predefined quality criteria. These principles are crucial in various fields, including software development, manufacturing, pharmaceuticals, and research, to guarantee reliability, safety, and efficacy.

The core idea behind validation is to provide documented evidence that something performs as expected. This involves a systematic approach that typically includes planning, execution, and reporting. Key aspects of validation principles involve establishing clear requirements and specifications, designing tests that adequately cover these requirements, and meticulously documenting all activities and results.

Common validation principles include the concept of "fit for purpose," meaning the system or product must be suitable for its intended use. Traceability is another important principle, ensuring that all requirements are linked to design specifications, test cases, and test results. Furthermore, validation emphasizes that it is a continuous process, not a one-time event, and that systems should be periodically revalidated, especially after significant changes. The principles also dictate the need for an independent review of the validation process and its outcomes to ensure objectivity. Ultimately, applying validation principles helps mitigate risks, reduce errors, and build confidence in the integrity and performance of the subject being validated.
