Validation and verification



The objective of validation and verification (V&V) activity is to confirm that certain information is reliable. It may be contained in statements, reports, logs, memories, etc. generally made by a company (but also by a group of people or other organizations).

Validating or verifying this information is carried out by obtaining and collecting objective testing or evidence that supports it. Such confirmation, depending on the temporal characteristic of the information, differentiates the terms "validation" and "verification”:

Validation applies to information (declarations, reports, etc.) that refer to events with forward-looking use or a projected result (likelihood).

Verification applies to information (declarations, reports, etc.) that refers to events that have already occurred or to results that have already been obtained (veracity).

The added value of these validation and verification activities is to give the recipient of the information confidence, such as administrations, consumers, schematic owners, manufacturers or other interested parties, in these statements or information.

However, in order to definitively achieve this trust, V&V services must demonstrate that they are competent for the activity they carry out and act with the necessary integrity. The only internationally recognized mechanism for demonstrating this is accreditation in accordance with UNE EN ISO/IEC 17029.

This standard, which will serve as the basis for all types of V&V, is applicable to validation and verification bodies in any sector and should be used together with programs and schemes with specific requirements for their validation and verification processes and procedures.

All ENAC documentation on validation and verification accreditation criteria and procedures can be found in the DOCUMENTS section.


Accredited services

Prior to the international publication of this standard, the market had accredited V&V activities for reports of greenhouse gas (GHG) emissions, such as the European Emissions Trading Scheme based on European regulation or the CORSIA Programme of the International Civil Aviation Organization (ICAO) accredited by ENAC in accordance with ISO 14065.

In addition to these activities, many possible applications are now open for declared and verified (or validated) information related, in particular, to new technology fields: energy management, financial and non-financial management (sustainability and social responsibility reports), machine safety, industrial automation systems, systems and software engineering, artificial intelligence, information technology, health care products and medical devices, safety and design engineering, etc.
