Object-Oriented Systems Engineering Method Working Group

Mission & Objectives

We are working to improve the practice of Object-Oriented Analysis and Design (OOA/D) applied to Model-Based Systems Engineering by applying concepts, notations, and methods that:
  • Support the capture, analysis, synthesis, and understanding of complex architectures, systems specifications, technologies, and designs.
  • Improve integration between engineering disciplines including but not limited to systems, human(s), software, hardware, test, environment, and logistics. Particular emphasis is on integration between systems engineering and software-level OOA/D.
  • Facilitate Family/Systems of Systems (FoS/SoS), system-, element-, and component-level reuse and design evolution.

Working Group Products

Recently the OOSEM Working Group:
  • Provided input to INCOSE Systems Engineering Handbook.
  • Sponsored December 2015 and December 2016 training workshops on Agile methods (with Chesapeake Chapter and IEEE).
  • Provided input to refinement of the Systems Modeling Language (SysML) Specification.

In 2017 the group will begin work on a new set of case studies.

Planned Working Sessions at the Next Events

If time and space are available, the OOSEM Working Group plans to host at IW17 a two-hour Outreach Session for anyone interested in OOSEM.

Planned Presentations at the Next Annual

If accepted, OOSEM Working Group representatives will facilitate at IS17 a 6-hour Agile Planning Tutorial.
