Comparing Philip Crosby, W. Edwards Deming and Joseph Juran

Deming believed that organisations could increase quality and reduce costs by practising continuous process improvement and by thinking of manufacturing as a system, not as bits and pieces. Juran applied the Pareto principle to quality issues (80% of the problems are caused by 20% of the causes) and also developed “Juran’s Trilogy”: quality planning, quality control, and quality improvement. Crosby’s response to the quality crisis was the principle of Doing It Right the First Time (DIRFT). He applied four major principles which are
• The definition of quality is conformance to requirements
• The system of quality is prevention
• The performance standard …show more content…

Juran believes that the quality is ‘fitness for use’ as known by customers and the mission of individual departments are to work according to specifications.

Degree of senior management involvement
Crosby believes quality improvement starts from the top. Senior management is responsible for all the problems with quality and their continuance.

Deming believes quality is decided in the board room.

Juran believes that majority of quality problems are due to poor management rather than poor workmanship.

Performance standard / Goal setting
Crosby believes that the performance standard must achieve zero defects. Groups should encourage individuals to establish improvement goals for themselves and their groups.

Deming eliminates management by numbers, numerical goals, as a substitute for leadership.

General approach
Crosby believes in prevention of poor quality and not appraisal.

Statistical process control / quality control
Juran believes that the concept of control is one of ‘holding the status quo’: keeping a planned process in its planned state so that it remains able to meet the operating …show more content…

Each department must see other department as an internal customer. When this is practiced the barriers begin to fall.

Single source of supply
Deming believes there should be a single supplier for any one item and it should be based on a long-term relationship of loyalty and trust.

Cost of quality
Crosby believes that the measurement of quality is the price of non-conformance and not indexes. The price of non-conformance is by counting everything that is spent if everything was not done correctly the first time.

Deming believes companies should look at the total cost of the product or service provided by others, and not just the purchase price. Accepting the lowest bid does not guarantee the lowest total cost.

Juran believes the cost of poor quality is the sum of all costs that would disappear if there were no quality problems. Quality improvement does no come free.

Quality awareness
Crosby believes in sharing with employees how much non-conformity costs the company. Deming accepts that quality awareness management must eliminate slogans, attempts to achieve zero defects yet set new levels of productivity for the work
