Turns workflows, data, causes, and improvements into a tangible result by describing the deviation, choosing a comparison case, and deriving causes and actions.
Core question: Which differences between should and is explain the observed deviation, and which of those differences are causal, contributing, or random?

EngineeringCategory: Engineering. Describes the method's domain of use.
Turns technical problems, hypotheses, and next steps into a tangible result by clarifying the symptom and system boundaries, breaking the fault space into areas, and narrowing the affected area.
Core question: Which system area most likely causes the symptom, and which tests narrow the fault domain further?
