SOPs are very complex artifacts. Although the SOP specifies actions that are performed using motor skills (e.g. pushing a button, dialing a knob, or moving a lever), a significant hidden part of the SOP is the decision-making that determines what action to take. This decision-making includes cognition for information gathering, information processing, conditional branching, and waiting/timing. Not all the information for decision-making is explicit in the documented SOP, however it is required for actual execution by the human operator.

In this way the execution of the SOP is a function of the timely, salient, unambiguous flow of information for decision-making. This flow of information can be modeled using LML/SysML models in a Model-Based System Engineering (MBSE) tool.

This book describes how to build models of SOPs using model-based systems engineering. Learn how to evaluate SOPs using heuristics and simulation. Start designing better standard operating procedures today.
