When determinations have been made concerning centralization or decentralization of quality work activities to the quality function—or to other components of the company—and after structuring has been considered for the work assigned to the quality function, a further area of consideration can be made. This is centralization or decentralization—within the quality function itself—into a quality-“assurance” component and a quality –“control” component. Section 8.17 discusses these questions.
