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 provide 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 systems engineering tool sets.

  • 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.  


The Working Group 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 Workshops and Annual Symposiums, create Technical Project Plans for selected projects and assign the Technical Project Leaders.

Chair: June 2016 - June 2019: John Nallon ; Co-chair Lonnie VanZandt

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.

Our Recent Activities at the INCOSE International Workshop 2018; Jacksonville, Florida USA

The TIMLM WG IW2018 Planned Day-to-Day Agenda is as follows:

Saturday January 20 

TIMLM WG Opening Session  

Getting started with a quick overview of 2017 and plans for 2018 and an introduction of our project leaders an contributors.

Tools Database Project Introduction 

INCOSE has initiated a joint project to develop a new web-based Systems Engineering Tools Database with Project Performance International. The database will be accessible from the INCOSE and PPI websites, with login access administered by INCOSE and PPI IT systems. This session will introduce the project plan and introduce the INCOSE and PPI Project Managers and Technical Leaders.           

The LOTAR for MBSE Project and PDES Inc./ INCOSE Collaboration  (Mark Williams)

INCOSE and PDES Inc. have established an formal working agreement to collaborate on projects to accelerate the development, the implementation, and the use of robust engineering data exchange standards in the digital enterprise. This session will announce this joint collaboration and provide an overview of the progress of a joint LOTAR for MBSE project.

MBSE Track:  SysML v2 Review (Sandy Friedenthal)         

User Perspective of SysML V2 (John Herrold and Robert Malone) 

SysML V2 Specification was broken into two different specifications with the SysML V2 Language RFP being issued on 12/2/2017 and the SysML V2 API and Service RFP which is going for OMG approval for submission in March 2018. As a result of negotiations with several OMG members, the original SysML RFP was broken into mandatory and non-mandatory requirements sections which we will go over in this session. There are several teams being formed to answer the RFP and we will review with you one team’s approach which is being led by Ed Seidewitz and Sandy Friedenthal.

OSLC - Time for an Update and Open Discussion (Axel Reichwein and Bill Chown) 

Sunday January 21 

 Criteria for a robust MBSE Environment discussion (Robert Malone, Boeing)

Evaluating and choosing a comprehensive Commercial-Off-The-Shelf (COTS) platform to serve as the basis for a deployable large scale Model Based Systems Engineering (MBSE) tool suite is a challenging task with many factors to take into account. Applying a Systems Engineering approach to the problem gives a highly useful roadmap for choosing an effective solution.

Modeling Standards and Boeing Methodology (Robert Malone, Boeing)

Through successful employment of large scale Model Based Systems Engineering (MBSE) over many years, The Boeing Company has developed an elaborate data model and associated constraining business rules that form part of its MBSE tool suite specifications. Advantages inherent in this core data model and business rule set are detailed.  These core data model elements and business rules should be applicable to modeling efforts across engineering domains.  A mapping of these core data elements to the SysML v2 RFP requirements is provided.                

Modeling and Data Interoperability Standards: Where to Next? (Mark Williams, Boeing; Don Tolle, CIMdata) 

There are a number of standards and industry collaboration initiatives underway to enable the vision of digitalization and model-based processes for engineering across the entire systems lifecycle.  This session will include  an overview of those initiatives and the specific MBSE standards and their perceived maturity. We will then discuss the gaps and highest priority items in relation to the industry’s business needs  and opportunities for global supply chain collaboration. ​​
