Maturity States

ASME Y14.47-2019 details a classification of maturity states that could prove useful for your technical data.

The maturity state describes the intended use of a data set for the product life cycle. The maturity state consists of four completeness levels: M1, M2, M3, and M4.

  • M1 (conceptual): a data set that is used when there is a need to verify preliminary design and engineering and to confirm that the technology is feasible and that the design concept has the potential to be useful in meeting a specific requirement.
  • M2 (developmental): a data set that is used for testing or experimentation and for the analytical evaluation of the inherent ability of the design approach to attain the required performance.
  • M3 (production): a data set that is used for the commission, operation, service, and decommission of a product.
  • M4 (archive): a data set that is used to store the product information for preservation [1].

This is a relatively new standardized concept, and very little guidance is given about how this might be applied.
