Study Notes

Cost of Quality

Prevention costs involve efforts to prevent defects from occurring
Appraisal costs are associated with detecting defects
Internal failure costs arise from defects that are caught internally and dealt with by discarding or repairing the affected items
External failure costs occur when defects reach the final customer
Prevention costs are the most vital, but appraisal, internal, and external failure costs are easier to collect
Even a small increase in prevention costs can significantly reduce appraisal and failure costs

Deming's Chain Reaction

The Deming Chain Reaction model suggests that improvements in quality lead to lower costs, higher productivity, and increased market share
Deming's approach emphasizes the importance of reducing variation in processes to improve quality
Higher quality leads to higher productivity and long-term competitive strength

Seven Types of Waste (MUDA)

Muda means ‘wastefulness’
The seven types of waste are:
- Waiting
- Defects
- Over-production
- Over-Processing
- Transportation
- Inventory
- Motion
Waiting refers to time spent waiting for materials, information, or processes
Defects result in rework or discarding of products
Over-production occurs when more products are produced than demanded
Over-processing refers to unnecessary work performed on a product
Transportation is the unnecessary movement of products within the company
Inventory refers to the storage of raw materials, work-in-process, or finished products
Motion relates to unproductive movement of people or equipment
Understanding and eliminating these wastes can lead to significant improvements in efficiency and profitability

Intangible Benefits

Intangible benefits of quality management include:
- Enhanced customer satisfaction
- Improved employee morale
- Increased company reputation
- Stronger relationships with suppliers
- Greater innovation and competitiveness
These benefits are difficult to measure financially, but they are crucial for long-term success
