How variability degrades performance and drives the need to make trade-off choices

How the variability in the product can be controlled and systematically reduced.

Question 1: Understand the narrow local focus of the quality cost model and the importance of controlling the process rather than inspecting out the defects.

Question 2: Use an SPC chart to identify special and common cause variability in a production process.

Question 3: Critically discuss how the PDSA cycle relates to the scientific approach and the culture of continual improvement.

Question 4: Critically discuss the wider implications of adopting a systems approach reflected in TQM and SS.

Question 5: Critically discuss how SPC relates to common practice and a wider systems perspective.
