MBSE driven approach for defining problem domain

This paper continues introduction of the MBSE Grid framework. As the name reveals, the framework is intended for model-based systems engineering (MBSE). MBSE is an emerging approach that applies modeling to support complex system requirements, design, analysis, and verification and validation activities. Being a synthesis of widely known MBSE methodologies (IBM Harmony, OOSEM, etc.) and frameworks (DoDAF, NAF, etc.), the MBSE Grid proposes an unambiguous workflow for modeling systems by iterations going from the highest to the lowest layers of abstraction. This paper mainly focuses on the Concept and Problem definition layers, describing in detail each step of the workflow in the range of these two layers and revealing presentation artifacts each step produces, also, giving clues for elements traceability. The case study demonstrates and proves adaptability of the MBSE Grid on a real-world problem domain using MagicDraw CASE tool.
