This paper applies the principles of Model Based Systems Engineering,(Oliver 1992a), (Oliver 1992b), to the systems engineering process itself. This results in layering the process description so that it is tailorable and supports aerospace or commercial methodologies. A core set of engineering steps is defined using a behavioral or conceptual model. Existing methodologies can be described and compared by selecting the core steps they use and the sequences, concurrencies, and iterations of the core steps selected. An information model, design model, is defined for each core step. From these models the possible representations of information are listed for each core engineering step. The graphic or text representations of existing methodologies can be mapped onto the information models to compare methodologies or to examine a methodology for redundancy or completeness. The design models are a basis for an information standard or a meta‐model for information exchange among tools, or for the selection of tools or notation.
