A better world through a systems approach

Tool Integration and Model Lifecycle Management Working Group



  Updated January 16, 2019

Mission & Objectives

The Tool Integration and Model Lifecyle Managament WG provides a forum for discussion and information dissemination on 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.

  • To characterize systems engineering tool integration and interoperability requirements.
  • To specify requirements and assess solutions for model life cycle management and data exchange.
  • To provide forums for discussion and information dissemination regarding tool integration, process implementation and effectiveness of data exchange standards.
  • To promote the development, validation and deployment of standards that advance the interoperability of systems engineering tool sets.
  • To address model lifecycle management concerns and to establish scenarios and best practices that address the needs of the community.
  • To determine efficient modeling structures to use including the repository, the models, and data within the models.  


The Working Group Chair maintain the direction of the working group, the collaborations with external organizations, as well as organize and track project progress. They are responsible for reporting the working group status to the Assistant Director for SE Transformation.

The Co-chairs attend the monthly Technical Operations meetings, annual International Workshop sessions and the annual  International Symposium meetings. The co-chairs organize and conduct the working group meetings at the International Workshops and Annual Symposiums, create Technical Project Plans for selected projects and assign the Technical Project Leaders.

Working Group Products

In collaboration with PDES Inc. the TIMLM WG participates in the application and analysis of data exchange standards and development of recommendations to improve the standards that define the integration and interoperability of systems engineering tools and data exchange. The TIMLM WG communicates with our members, numerous vendors, standards groups and professional organizations interested in further developing the data exchange capabilities and the management of models throughout the lifecycle of a product.

In collaboration with Project Performance International (PPI) the TIMLM WG  is developing the next generation Systems Engineering Tools Database (SETDB). The project leaders are communicating with our members, numerous vendors, INCOSE and PPI stakeholders and Working Groups that are interested in developing a new tools body of knowledge.

Planned Working Sessions at the Next Events

This Tools Integration and Model Lifecycle Managment Working Group participates in weekly working sessions for our main projects. We also hold working sessions every year at the International Workshop (Jan/Feb) and the International Symposium (Jun/Jul). All working group members receive schedule and agenda announcements via the working group e-News, and  the event planning details are posted on the working group web-site and in INCOSE CONNECT. INCOSE or Non-INCOSE members with interest in this working group may inquire about activities and questions by contacting Chair - John Nallon

The Agenda for for the INCOSE International Workshop 2019; Torrance, California USA January 26 - January 29, 2018 is now available at: IW2019 Agenda

  • Lotar for MBSE Project Sessions: Led by Mark Williams, Project Lead, MBSE Process and Tools, The Boeing Company on Monday January 28, 2019 from 1 PM until 5 PM. : To realistically reduce the cost of developing new products the Systems Engineering community must evolve from our document based paradigm and embrace Model Based Engineering.  The foundation of this evolution is MBSE.  But the slow implementation of MBSE is an industry problem that relies on data standards, defining WHAT must be exchanged, HOW to exchange, data interoperability and preservation.  We also need Leadership and a robust source of Vendor products.  Any alternatives must include not just the OEMs, but also the supply base.

This presentation addresses some of those issues, and the communities engaged in identifying  potential opportunities and solutions.  Can you identify the role of PDES, LOTAR, and/or the industry consortium aligned to implement change?  Bring your questions and ideas to this two part session inspired by the need to empower INCOSE’s thriving membership.

  • SE Tools Database Project: INCOSE has initiated a joint project to develop a new web-based Systems Engineering Tools Database with Project Performance International (PPI). The database will be accessible from the INCOSE and PPI websites, with login access administered by INCOSE and PPI IT systems.  A full series of meetings is scheduled from Saturday January 26, 2019 to January 29, 2019 to review specifications, plans and to conduct working meetings.
  • MoSSeC (AP243) Standard and Model Interoperability Presented by Greg Pollari - Collins Aerospace on Sunday January 27 0900-1030. The globalization of the aerospace and defense industries is driving large volumes of work for modelling and simulation of product performance and behavior, into geographically distributed teams and into the supply chain. The modelling and simulation technical data is used to justify change decisions and to validate the product throughout development, certification and in-service. There are already mature standards for exchange of the modelling and simulation technical data, but these either do not include traceability to the systems engineering and product data management context, or are inefficient for data sharing. This context information can be summarized as “who”, “what”, “where”, “when”, “how”, “why”, and the goal of the MoSSEC project is to provide the standard for sharing this information. The MoSSEC project will be agnostic of the type of modelling and simulation, and it is the intention that the modelling and simulation data will continue to be exchanged with the technical standards in use today (e.g. AP209, AP210, AP242, FMI). This presentation will describe the rationale and context for the work, provide the status and future plans of the project (developed as part of the ISO suite of STEP standards).
