This paper considers model based systems engineering which produces executable requirements and specifications. It describes the trade‐off step of the systems engineering technical process. It treats the inputs to the trade‐off step. It defines a behavior for systems engineers to follow in performing trade‐off analysis. That behavior is described as an executable meta‐process rather than as a methodology to make it independent of the plethora of methodologies. A meta‐process describes the steps to be taken in the process, the ordering of the steps and the inputs and outputs to each step. This is a behavioral picture. It also describes the information handled at each step and the relationships among the pieces of information. This is a static structural picture sometimes called an object model or an information model. The meta‐process defines the possible views of the information that will be handled. A methodology, in contrast, selects particular orderings of the engineering steps and particular views of information in particular notations for use by an engineering team.
