While a system-modeling language such as SysML is a formal syntactic language, it is still based on elements of human language. As an example, are some estimation methods exclusively connected to some models? Applying systems thinking, we can recognize that there are three systems involved in the modeling process: the designed system, the designed system's context, and the modeling organization for the designed system. Lin, K., Travlos, D. V., Wadelin, J. W., & Vlasses, P. H. (2011).
