Designers should ensure that the quality of products is consistent through development of detailed manufacturing requirements. They also need to focus on the means to achieve it. The importance of quality management through quality control (QC), statistical process control (SPC) and quality assurance (QA) reduces the potential waste of resources.

• Quality control (QC)

• Statistical process control (SPC)

• Quality assurance (QA)

• How QC at source eliminates waste from defects

• How continuous monitoring ensures that machines perform to the pre-determined standard/quality

• How QC, SPC and QA contribute to quality management

• The differences between QC, SPC and QA

The implementation of quality management strategies requires a critical and complete understanding of the needs of a product. To ensure efficiency and efficacy, these measures need to be designed into the product and its production system.
