Tool Integration and Model Lifecycle Management Working Group

             Enabling Integrated Tools, Processes and Managing Models in a Model Based Systems Engineering Environment

Mission & Objectives

The TIMLM WG mission is to capture best practices and guidelines for using computer based tools, exchanging data between tools and be able to operate on the data without human intervention. The TIMLM WG provides a forum for discussion and information dissemination on tool integration, process implementation, operational behavior and model management to promote the development, validation and deployment of standards that advance the interoperability of systems engineering toolsets.

  • To characterize systems engineering tool integration and interoperability requirements.
  • To specify requirements and assess solutions for model life cycle management.
  • To foster efficiency of systems engineering process execution through integrated processes, tools and environments including design, manufacturing and sustainment lifecycle systems.
  • To provide forums for discussion and information dissemination regarding tool integration, process implementation and operational behavior.
  • To promote the development, validation and deployment of standards that advance the interoperability of systems engineering toolsets.
  • To address model lifecycle management concerns and to establish scenarios and best practices that address the concerns of the community.
  • To determine efficient modeling structures to use. Structures include the repository, the models, and data within the models.  


Co-Chairs 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 Transformational Working Groups. 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 Workshop and Summer Symposiums, create Technical Project Plans for selected projects and assign the Technical Project Leaders.

Co-chairs June 2016 - June 2019: John Nallon and Lonnie VanZandt


Working Group Products

Project deliverables are defined in the TIMLM WG Technical Project Plans (TPP). TPP’s are developed, submitted and tracked as defined by the applicable Technical Operations procedure for each working group project. Historical deliverables are stored in the TIMLM WG CONNECT site and include: An Integrated Systems Engineering Environment (DRAFT), Systems Engineering Tools Matrix (including MBSE Tools), tool interoperability analysis results, model lifecycle management, and presentations and reports from the PDES Inc and OSLC Liaison projects.

The TIMLM WG provides information services for other Working Groups to consider in developing their own agendas and plans that involve the use of computer based tools in the execution of their plans. Frequent requests from INCOSE Working Groups, the Standards Initiative, and the MBSE activity groups are supported as needed.

The TIMLM WG provides services to the Standards Initiative for developing international standards that involve the integration and interoperability of systems engineering tools and data exchange. The TIMLM WG communicates with numerous vendors, standards groups and professional organizations interested in or working on integration and interoperability as requested by INCOSE leadership or membership.

The TIMLM WG has developed a few surveys to help us gather information regarding tool integration and model life cycle management. Reports are generated from these surveys and used for a variety of tool related projects, including the maintenance of a Systems Engineering Tool Matrix. Please take a few minutes to fill out a survey and help us plan the future of tool integration and model life cycle management in the systems engineering domain. Thank you in advance.



Planned Working Sessions at the Next Events

This Tools Integration and Model Lifecycle Managment Working Group holds working sessions every year at the two main INCOSE events: the International Workshop (usually Jan/Feb) and the International Symposium (usually Jun/Jul). All working group members receive schedule and agenda announcements via the working group e-News, and all INCOSE members can view the event planning details on the working group web-site in INCOSE CONNECT. INCOSE or Non-INCOSE members with interest in this working group may inquire about activities and questions by contacting Co-Chair - John Nallon  or Co-Chair Lonnie VanZandt.
