Deming’s 14 Points• Establish the objective of constant innovation and
improvement
• Adopt a new philosophy, we cannot accept the old mistakes and defects
• Cease dependence on mass inspection, require statistical evidence that quality is built in
• End the practice of awarding busines on the basis of price
• Use statistical methods to find troublespots
• Institute modern methods of training on the job
• Improve supervision - do what is right for the company, don’t just turn out the required quantity
Deming’s 14 Points
• Drive out FEAR ....
• Break down BARRIERS ...
• Eliminate posters and slogans
• Eliminate work standards that prescribe a numerical quota
• Remove barriers between workers and their right to pride in workmanship
• Institute a vigorous retraining program
• Create top management structure that will push EVERY DAY for these points

ISO 9000• Standards for companies doing business in the
EC• Certification by hearing from qualified
external examiner• Certification does NOT mean anything about
quality of a product ....• Instead, it means that company can provide
documentation supporting their quality claims.
