A Japanese concept representing deep processes and perfection in quality that transcend mere education and persistence, emphasizing a mindset committed to excellence.
Leaders in Quality Management
W. Edwards Deming: Advocated for quality improvement through management responsibility, promoting the idea that improving quality is the key to economic survival.
Joseph M. Juran: Focused on the need for management commitment to quality and customer needs as the foundation of quality management success.
Armand Feigenbaum: Proposed integrating quality processes throughout the entire organization, not just within production, for comprehensive quality assurance.
Philip B. Crosby: Coined the concept of zero defects, asserting that the financial implications of poor quality can be massive, and emphasized that prevention is cheaper than correction.
Ethics in Quality Management
Operations managers have a responsibility to provide safe and quality products, aligning ethical practices with organizational goals.
Ethical dilemmas can arise from poor quality leading to safety risks, product recalls, and damaging reputational consequences for the organization.
Total Quality Management (TQM)

Before customer delivery: Final checks to ensure quality standards are met.
At customer contact points: Assessing service quality where customer interaction occurs.
Attributes vs. Variables
Attributes: Binary measurements defining the quality as acceptable or unacceptable (e.g., pass/fail).
Variables: Measurable characteristics that provide a range of values (e.g., weight, speed), utilizing statistical methods for quality assessment.
TQM in Services
