Pulling Threads: The Value in Systems Engineering

by dlong

By David Long, Vitech President

There are two great miracles in systems engineering – where the requirements come from and how you get from requirements to implementation. Where requirements come from is a topic for later (it need not be a miracle or a mystery). As for moving from requirements to implementation, that requires a blend of a creative and analytic thinking. The best path does not involve miracles. The best path moves from requirements to behavior to implementation, and threads are the key to tying together requirements and behavior. More...

6 Steps in Engineering Your MBSE Deployment

by dlong

By David Long, Vitech President

As individuals and organizations deploy model-based systems engineering, the unwary fall into several traps: starting too big (or too small), chasing standards, focusing purely on the tool (or technical) dimensions, and more. In an earlier blog, I discussed 7 classic errors or anti-patterns to avoid. As we look for positive patterns to implement, there is no “one size fits all” deployment model that will work for every organization and every situation. However, at the risk of being too much of a systems engineer, we can choose to treat this as a systems problem, spending time to analyze the problem and context before moving to implementation. Just as we systems engineer our products, we can – and should – engineer our organizations, processes, and change initiatives. Practicing what we preach, there are six simple steps that will fundamentally change the impact and increase the likelihood of success of your MBSE deployment.  More...
