Maturity and Completeness States

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

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


Describes the intended use of a data set for the product life cycle.

Designator [1] Name Description
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.”

Geometry Completeness

Describes the level of detail present in a model.

Designator [2] Name Description
G1 None “The model that is created with no distinctions made for individual features.”
G2 Partial “The model that has a portion of the features represented.”
G3 Full “The model that has all features represented.”

Annotation and Attribute Completeness

Describes the completeness of attached annotations and attributes.

Designator [3] Name Description
A1 None “No annotations or attributes that are in the data set are intended to be used to define the product.”
A2 Partial “The data set that contains a subset of all of the annotations or attributes intended to be used to define the product.”
A3 Full “The data set that contains all of the annotations or attributes [including items such as general notes and other product and manufacturing information (PMI)] without querying the model geometry intended to be used to define the product.”
