    Juran's Trilogy

    Juran's Quality Trilogy is an approach to cross-functional management that is 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 customer's 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

    This process consists of the following steps:
  • Evaluate actual quality performance
  • Compare actual performance to quality goals
  • Act on the difference
  • 3. Quality Improvement

    This process is the means of raising quality performance to unprecedented levels (breakthrough). This involves:
  • 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 not getting it right the first time, Juran maintained 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

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

The term "Trilogy" is associated with which quality guru?
