Quality Management & Control Flashcards
What are the effects on an organization if its services/goods are of poor quality?
Higher transformation costs (rework, scrap, etc.)
Loss of sales (short term)
Loss of reputation (long term)
Higher warranty costs (returns, repairs, etc.)
Lawsuits

- Investigate
- Prevent
Explain Control Costs
Control costs are proactive and aim to improve quality.
Are failure costs reactive or proactive?
Failure costs are reactive.
How can the Cost of Quality be improved?
Quality can be improved if money can be moved out of “failure”
costs and into “control” costs (no “new money” needed)
Explain the Traditional View in Proactive Quality Control
The traditional view in proactive quality control includes appraisal, which is evaluating or inspecting. This increases appraisal costs, so quality goes up, but costs also go up. An example is an impaired driving checkstop.
Explain Deming’s View in Proactive Quality Control
Deming’s view in proactive quality control includes prevention, where process quality is increased. This increases quality while minimizing costs. An example is an anti-drinking and driving campaign.
Identify five preventative measures from the Honda video clip.
Doors taken off at start of assembly process
Plastic “film” placed on car exterior at start of assembly process
Materials used in design of product
Magnetic “Label” template for location / level
Ring & watch guards
Define Failsafing (Idiot-Proofing)
Creating a control condition where the customer or employee can only take the correct action while performing the process.
List 3 Examples of Failsafing

Explain the benefits of checklists in prevention.
Effective and efficient
Formalize previous lessons learned
Share Best Practices
Improvement is typically immediate and significant
What is Six Sigma?
Goal: to reduce process variation to the point where only 3.4 defects per million are produced by a process that involves a high volume of manufactured units or service transactions.
What is the PDCA Cycle?
Plan: The improvement (objectives / specifications)
Do: Implement the improvement plan
Check: Actual results versus planned results
Act: “Adjust” so actual meets planned results
- Developed by Walter Shewhart (1891-1967)
- Principle of continuous improvement
What is ISO 9000?
“Generic management system standards” to provide a single set of standards that people everywhere will recognize and respect. They are process standards, not product standards.
What is ISO 14000?
“Environmental management“ minimizing harm and to achieve continual improvement of its environmental performance.
