class Flashcards
Explain the Kano-model
Excitement, Performance, Basic. Change over time. Implementation and satisfaction.
Explain the shift of the view of value
From company create to co-create. Value is determined by the user
What is the Gap model?
The different gaps between a service and a product.
What is PDCA?
Plan, do, check, act.
What is Six Sigma?
DMAIC (decide, measure, improve Belt Organization (karate) Bottom line focus (money) Customer focus Based on facts Reduction of variation Six Sigma toolbox
What is DMAIC?
Decide, measure, analyze improve, control.
What are the cornerstones of TQM?
Customer focused Base decisions on facts Focus on processes Committed leadership Improve continuously Let everybody be committed
Explain the difference between full factorial design and fractional?
Full FD- Higher certainty, more resources. All combinations.
Fractional FD - Effects are mixed. Less resources.
Why should you randomize tests?
Changes in external factors. Less likely to add up. Temperature etc.
Repetiotions/replications
Repetition - multiple runs.
Replications - Do again from scratch.
Principles of DoE
- Hierarchical Principle, usually main factors are active (not higher order)
- Heredity Principle, usually the first order factor is active when higher order is active.
- Sparsity Principle, usually a few factors matters. Vital few and trivial many.
What are interactions in DoE
When two factors have a “holistic” effect.
Why is DoE better than OFAT
Interactions and noise reduction.
What is Design for Six Sigma
- Satisfy customer expectations and needs
- Identification of critical to quality characteristics (CTQs)
- Focus on robustness
- enable Six Sigma levels in production
Four parts in a QFD (quality function deployment) process?
Market analysis
Examination of competitors
Identification of key factors
Translation of key factors into product/process characteristics
