Model-Based Characteristics v1.0 – Persistent Identification and Related Digital Practices (new standard)
The Model-Based Characteristics Standard (MBC) was developed in 2023 by domain experts from the manufacturing quality community representing a wide variety of industries and quality measurement needs under the direction of the Digital Metrology Standards Consortium (DMSC).
The DMSC™ is an American National Standards Institute (ANSI) Accredited Standards Developing Organization, as well as an A-Liaison to the International Standards Organization (ISO).
The new MBC standard (released xx/xx/2023) defines nomenclature, definitions, symbols, data structures, and practices for identifying, communicating, and exchanging model-based characteristics with various optional augmentations through both a logical data model and supporting documentation. Specifically, this standard provides a common approach for tagging and uniquely identifying product characteristics that are of interest for the product realization process.
Product characteristic tagging is primarily used for identifying a list of characteristics required to verify and accept product. Additionally, it can enable explicit referencing for product definition, change control, reporting on product non-conformance, and obfuscating confidential or classified product definition information. Moreover, this standard provides optional augmentations for communicating criticality classifications, product requirement associations, and verification plan requirements. Finally, this standard shall be applicable for both human-readable communication and machine-readable applications that can enable the digital thread.
Development Process
In June 2020, the DMSC began the development of this new metrology standard to provide a common approach for tagging and uniquely identifying product characteristics that are of interest for the product realization process in a Model-Based environment. The goal was to create an ANSI/ISO standard that would be applicable for both human-readable communication and machine-readable applications that can enable the digital thread.
After three years of effort by way of the DMSC Working Group process, a completed standard proposal moved through the DMSC Standards Committee for fine-tuning and approval as part of the ANSI development process. At an in-person meeting, the Standards Committee vote was overwhelmingly affirmative, and the proposal moved to the next step in the ANSI approval process.
Standard Status
The new DMSC standard proposal appeared in the August 25, 2023 edition (page 25) of the ANSI Standards Action, and according to ANSI procedures, was made available for Public Review for a period of 45 days. Comment deadline expired October 9, 2023. Comments are now being forwarded to DMSC for response.
Following the Public Review period, the proposed MBC standard is now subject to an ANSI special audit to assure compliance with all ANSI procedures. An audit date is yet unspecified; we are waiting for confirmation of the ANSI audit schedule, potentially as soon as November 2023.
The last step in the process would be a final review by an ANSI committee, at which point ANSI would publish the MBC proposal as an official ANS (American National Standard).
