Tool Integration & Model Lifecycle Management Working Group

Provides a forum for discussion of best practices, methods and processes that promote the development, validation and deployment of standards to advance data exchange capability of digital data created during a product development lifecycle.

Working Group Purpose & Mission

Mission:

The Tool Integration and Model Lifecyle Management WG provides a forum for discussion and dissemination of best practices, methods and processes that promote the development, the validation and the deployment of standards to advance the exchange of digital data between MBSE tools and toolsets.
MOSSEC

Several INCOSE working groups are working with the TIMLM Working Group on the development of the LOTAR NAS 9300-xxx series of Long Term Archival and Retrieval (LOTAR) of standards for MBSE. Our working group is directly supporting PDES/LOTAR working groups to develop the LOTAR for MBSE standards. Our Mou with PDES Inc. enables INCOSE to participate in ISO and LOTAR development with several other standards organizations as shown in the following organization model:  LOTAR_Overview

Scope

The TIMLM WG is focused on the interoperability of tools, data, models and processes as they relate to a Systems Engineering process and methods throughout the acquisition and product development life cycles. The TIMLM collaborates with standards organizations such as PDES Inc., LOTAR, other STEP organizations and the INCOSE Standards Development Department to advance the data exchange standards to meet our stakeholders needs.

Goals

  • To provide the systems engineering community a reliable source of information about tool data exchange and interoperability  standards used during the execution of their business processes in the product lifecycle.
  • To collaborate with standards organizations and other supporting INCOSE Working Groups to characterize systems engineering tool integration and interoperability requirements for tools and data standards for the exchange of Model Based Systems Engineering (MBSE) digital artifacts.
  • To promote the development, validation and deployment of standards that advance the interoperability, storage, archival and retrieval of digital data and artifacts produced by systems engineering processes.
  • To provide a forum for the discussion and dissemination of information regarding tool interoperability, data exchange, use cases for applying  data exchange and interoperability standards and discussing interoperability accomplishments of in our systems engineering community

Activities and Coming Events

  1. PDES MBSE and LOTAR MBSE Workshops are conducted quarterly and are detailed on our Viva Engage site. 
  2. PDES/LOTAR/TIMLM meetings are held weekly every Wednesday from 08:30 to 10:00 AM (Central Time USA) and open to all interested parties. Contact us at [email protected] for a meeting invite. These are virtual meetings on ZOOM.
  3. ISO-10303-AP243 (MoSSEC) has been approved by ISO and released to the public. PDES/INCOSE/LOTAR has embraced this standard for model exchange and is updating all specifications and standards accordingly.
  4. The NAS9300-500 LOTAR for MBSE standard has been submitted for review to AIA and ASD-SSG standards organizations. A copy of this submittal with review updates is available on our Viva Engage site.
  5. A Model Portfolio Management Guideline has been published as an INCOSE product and is available in the INCOSE Store for downloading. It is free to INCOSE Members. A second edition is being planned.
  6. Our next event will be the LOTAR 2nd Quarter workshop and will be available for virtual participation.

The EN/NAS 9300-500 standard outlines essential MBSE information that should be archived, including requirements, system architectures, numerical analyses, and verification & validation data. It introduces verification and validation (V&V) procedures to maintain data authenticity and usability, emphasizing compliance with international standards such as ISO 10303 and ISO 14721. The standard also details structured data retention policies, archiving workflows, and the use of Archive Information Packages (AIPs) to manage metadata and dependencies. By defining maturity milestones, use cases, and a preservation framework, NAS9300-500 provides a scalable and adaptable approach to digital engineering data management across an MBSE lifecycle.

LOTAR for MBSE

The NAS9300-500 standard defines the fundamental principles and processes for the long-term archiving and retrieval of Model-Based Systems Engineering (MBSE) data in the aerospace and defense industries. It establishes methods to preserve digital technical product documentation, ensuring data integrity, accessibility, and interoperability over time.

 

The NAS9300-P500 has been submitted to ASD Europe and the AIA USA for their review and approval. We have since made several corrections to the Glossary and Bibliography; so we are now at V42. This gives everyone one more chance to submit comments and updates and we are expecting to lock-down the next version sometime in April, so you don't have much time if you would like to review and comment on this important standard.

 

Version 42 of the NAS9300-500 is available for download in our Viva Engage Library at: NAS 9300-5xx Files for Review
