Juran's Trilogy

Juran's Quality Trilogy is an approach to cross-functional management composed of three managerial processes: Planning, Control, and Improvement.

1. Quality Planning

Quality Planning is the activity of developing the products and processes required to meet customers' needs. It involves:

  • Establish quality goals
  • Identify the customers- those who will be impacted by the efforts to meet the goal.
  • Determine the customers' needs
  • Develop product features that respond to customers' needs
  • Develop processes that can produce those product features
  • Establish process controls, and transfer the resulting plans to the operating forces

2. Quality Control

Quality Control is the activity of monitoring production activities to ensure that they are producing the correct product or service according to plan. It includes:

  • Monitoring the performance of the processes
  • Ensuring that all steps in the process are performed correctly
  • Corrective action when necessary

3. Quality Improvement

Quality Improvement is the activity of making changes to improve the process and raising quality performance to unprecedented levels (breakthrough). This may involve:

  • Establish the quality improvement infrastructure
  • Identify the improvement projects
  • For each project, establish a project team with clear responsibility
  • Provide the resource, motivation, and training needed by the team

Cost of Quality

The cost of quality (or the cost of not getting it right the first time) should be recorded and analyzed and classified into failure costs, appraisal costs and prevention costs.
1. Failure Cost
Scrap, rework, corrective actions, warranty claims, customer complaints and loss of custom
2. Appraisal Cost
Inspection, compliance auditing, and investigations
3. Prevention Cost
Training, preventive auditing, and process improvement implementation


Pareto Principle

Vilfredo Pareto was an Italian economist who observed that 80% of the effects come from 20% of the causes. Juran applied his observations to business management and economics.

Juran emphasized that 80% of problems are created by 20% of causes. Organizations should identify the vital few (20%) causes and take action to remove them from the system.


Quality Improvement - 10 Steps

Juran proposed ten steps to quality improvement:

  • Build awareness of the need and opportunity to improve
  • Set goals for that improvement
  • Create plans to reach the goals
  • Provide training
  • Conduct projects to solve problems
  • Report on progress
  • Give recognition for success
  • Communicate results
  • Keep score
  • Maintain momentum
