As one examines dynamic models of natural or human‐created mechanisms, it is apparent that they can be applied by analogy or reused over a broad range of architectural scales. For purposes of rapid analysis and decision support in a continually changing world, models must be simple and parametric. The dynamic characteristics of three simple models (the Control Hierarchy, Percent of Job Completed, and the Logistics Equation) constructed in a computer‐based simulation tool, are presented. A complete baseline for assessing model reuse, includes the life cycle domains of product and process, identified in current theories and standards on systems engineering improvement, plus the enterprise. Enterprise here is the high level entity that capitalizes, develops and changes corporate and social processes. Parametric context changes, necessary for applying the models across domains are discussed, the most critical being increasing uncertainty of resources and environment, as scale and complexity increase.
