Introduction to Quality


Quality

  • Quality is a judgement by customers or users of a product or service
  • That is, quality is a customer determination, not an engineer’s determination or manager’s determination.
  • Quality of a product or services is its ability to satisfy the needs and expectations of the customer

Various definitions of Quality

  -Deming
  • Quality is in its essence, a way of managing the organisation.
  -Feigenbanum
  • Quality is correcting and preventing loss, not living with loss.
Hoshin
  • Quality can be quantified as follows,
Q = P / E
where,
  Q = Quality
  P = Performance
  E = Expectation
  • If Q is greater then 1.0, then the customer has a good feeling about the product or service.
