Quality by Design

Definition: Quality by Design is a quality management philosphy by Juran arguing that quality should be planned:
'Numerous specific quality crises and problems have been traced to the way in which quality was planned in the first place. In a sense, we planned it that way. There is no implication that the planners were incompetent, malicious, or otherwise deficient. On the contrary, the planners have generally been quite experienced and dedicated. Instead they faced multiple obstacles: unrealistic schedules, tight budgets, inadequate data bases. However, none of these realities diminishes the validity of the assertion that "we planned it that way."'
