Introducing methodologies

Methodologies are an important part of any systems engineering endeavor. Methodologies sit firmly in the Approach section of the MBSE in a slide diagram that has been referred to throughout this book.

Methodologies may include aspects of both frameworks and process sets but differ from frameworks and process sets in that they will define more details regarding actual techniques that may be used at specific points in a process, or they will define specific views in a framework. For example, a process will define the activities that need to be executed and the artifacts that must be created by such activities. However, a typical process does not go into detail about how each activity should be realized, as there may be many ways to do so. It may be, for instance, that a specific methodology uses a particular notation and toolset, whereas another methodology may realize the same activity using a different notation and toolset.
