We often think of systems engineers and software developers as two separate roles. However, a relationship between the two is key. As the Systems Engineering Body of Knowledge says, “Software engineering and systems engineering are not merely related disciplines; they are intimately intertwined.” Good software requires synergy between the systems engineering team and the software development team. Let’s look […]
Happy Fourth of July everyone! With Fourth of July less than a week away, we at SPEC Innovations want to celebrate the birth of our nation with a tribute to some of its greatest achievements in systems engineering. The United States has been a leading technological innovator for hundreds of years, as the first country […]
In an earlier blog I talked about optimization of cost, schedule and performance for the systems as the primary reason for modeling, but I realized that there was another, perhaps simpler way to look at modeling. But before we get to that we have to define the type of modeling we are discussing. Engineers develop […]
Everyone is talking about “Model-Based Systems Engineering” or MBSE, but why are we modeling? What are we supposed to be getting out of these models? To answer these questions, we have to go back to basics and talk about what we are doing as systems engineers. We often say that the job of a systems […]
Model-Based Systems Engineering (MBSE) has become a popular buzzword. Everyone talks about “modeling” and “simulation.” Unfortunately, many have conflated the concept of a model with a set of drawings or a specific drawing. MBSE originally meant capturing information that describes a system and then viewing that information in many different ways to enable understanding and […]
MBSE is one of the latest buzzwords to hit the development community. The main idea was to transform the systems engineering approach from “document-centric” to “model-centric.” Hence, the systems engineer would develop models of the system instead of documents. But why? What does that buy us? Switching to a model-based approach helps: 1) coordinate system […]
We often say that the job of a systems engineer is to “optimize the system’s cost, schedule, and performance, while mitigating risks in each of these areas.” Note that this is essentially the same thing that the program manager does for the program, hence the close relationship between the two disciplines. Everyone is talking about […]
