Introducing Model-Based Systems Engineering (MBSE) into an Existing/Legacy/Maintenance Project


Methodologists have devised many workflows for building Systems Engineering models. Methodologies including Harmony aMBSE, the MBSE Consulting and Training Method, and Object Oriented Systems Engineering Method (OOSEM) do a very good job leading the Systems Engineer from a clean sheet of paper to a completed Systems Engineering model that is ready for hand-off. But what does one to do when the system already exists?

A great many projects add functionality to an existing, functioning system. Systems Engineering models work very well for these mid-life upgrade, legacy, or maintenance projects, but these projects have limitations. Often the architecture and interfaces were defined years ago and cannot change without incurring huge costs. Furthermore, it is impractical and expensive to build a model for those parts of the system that aren’t going to change.

This presentation offers an approach for specifying new functionality for existing systems using Systems Engineering models. It explains the problems unique to specifying new features for existing systems and provides a proven workflow for building and integrating the new features.

We have helped our clients:
  • Increase productivity by 25-75%
  • Reduce development costs by 50-60%
  • Accelerate time to market by 20-40%

SAFe provided the agility, visibility, and transparency needed to ensure we could integrate with numerous other efforts, get predictable in our delivery, and ensure timelines are met.
