AFI16-1001 covers VV&A roles, processes, documentation, repositories, and federated architectures. It requires lifecycle V&V, accreditation for specified uses, and certification of data for specific applications.

Applies to: This instruction applies to all Air Force (owned or managed) models and simulations that qualify as federation elements, common-use, general-use, or joint modeling & Simulation as defined in the DoD online Modeling & Simulation Glossary.

Topics covered

  • Model verification and validation
  • Model accreditation
  • M&S data certification
  • VV&A functional roles
  • VV&A documentation
  • M&S repositories
  • Federated architectures

Questions and answers

How long must verification and validation continue for an Air Force model?

Verification and validation (V&V) will be a continuous process throughout a model’s life cycle. (paragraph 2)

Which Air Force models and data must undergo V&V?

Air Force models, simulations, and associated data used to support DoD processes, products, and decisions shall undergo V&V throughout their lifecycles. (T-0). (paragraph 2)

When must Air Force M&S applications be accredited?

Air Force M&S applications will be accredited for their intended purpose when supporting major DoD decision-making organizations or processes, joint training, and joint exercises. All executed V&V activities will support the model acceptance and accreditation requirements defined by the accreditation authority. (T-0). (paragraph 2)

How must data used in models and simulations be handled?

Data used in models and simulations will be verified, validated, and certified for use in specific applications. (paragraph 2)

What does accreditation allow?

Accreditation is the final step that allows use of a validated and verified model for a particular application or period of time. (paragraph 2)
