Reconciling Quality Requirements over the Product Life Cycle
- 3 Downloads
The requirements on product quality at all stages of the life cycle are analyzed. The characteristics on which requirements are imposed are noted. Common characteristics present at all stages of the life cycle are identified. It is found that the requirements on the common characteristics at different stages of the life cycle may be inconsistent. These requirements may effectively be reconciled if the requirements on the characteristics established at the operational stage are lowered.
