The CTQ Flowdown as a Conceptual Model of Project Objectives

Summary: [This abstract is based on the authors' abstract.]The critical quality flowdown (CTQ) is a tool that is the core of the definition phase of most quality improvement projects. It relates high-level strategic focal points to project objectives which in turn are linked to and decompose into CTQs made operational in the form of measurements. CTQ flowdown provides clear project definitions, clarifies the business rationale of an improvement project, and facilitates optimally solving trade-off problems. A theoretical grounding of the CTQ flowdown is given in addition to a prescriptive template useful to practitioners.
