Study Notes

Quality Management

Defining Quality:
User-based: Focuses on better performance and more features.
Manufacturing-based: Emphasizes conformance to standards and producing products correctly initially.
Traditional definition: "Quality means fitness for use." Products/services must meet user requirements, considering quality of design and conformance.
Modern definition: "Quality is inversely proportional to variability." Higher quality is linked with less variation in products/processes.
Quality's Competitive Advantage:
Builds reputation, increasing demand and sales.
Reduces costs by minimizing rework, scrap, and warranty expenses.
Total Quality Management (TQM) Activities:
Flow: Organizational practices lead to quality principles, employee fulfillment, and finally customer satisfaction.
Key Dimensions: Performance, reliability, durability, serviceability, aesthetics, features, perceived quality, conformance to standards, value.
Costs of Quality:
Prevention costs: Expenses related to defect prevention during design & manufacturing.
Appraisal costs: Costs of measuring, evaluating, and inspecting products to ensure conformance.
Internal failure costs: Expenses incurred when defects are detected before product shipment.
External failure costs: Expenses arising from defects identified after product shipment.

Implementing TQM

TQM Strategy: Organization-wide quality improvement plan. Focuses on training, quality awareness, customer focus, supplier quality, and aligning quality systems with business goals.
Quality Teams:
Quality council: High-level teams for strategic initiatives.
Workforce level teams: Focus on daily production processes.
Quality circles: Cross-functional teams managing specific quality improvements.

Seven Concepts of TQM

Continuous Improvement: Utilizing the Plan-Do-Study-Act (PDSA) model.
Six Sigma: Methodology to reduce defects, lower costs, and improve satisfaction (DMAIC - Define, Measure, Analyze, Improve, Control).
Employee Empowerment: Involving employees in product and process improvement decisions.
Benchmarking: Identifying best practices for performance comparison.
Taguchi Concepts:
Robustness: Producing consistent quality despite environmental variations.
Quality Loss Function: Measures the cost associated with quality deviation from standards, highlighting the expenses from slight deviations from requirements.
Target-Oriented Quality: Aims for precise product specifications, emphasizing continuous improvement to meet the target.
Knowledge of TQM Tools:
Check Sheet: Data recording tool for identifying trends in defects.
Scatter Diagram: Visualizing relationships between two variables.
Cause-and-Effect Diagram (Ishikawa Diagram): Illustrates various influences on a problem, addressing materials, methods, manpower, and machinery.
Pareto Chart: Ranking problems/defects by frequency.
Flowchart: Describing process steps.
Histogram: Visualizing data distributions.
Statistical Process Control (SPC) Chart: Monitoring process standards, identifying and addressing variations.
Natural Variation: Common causes (expected variation).
Assignable Variation: Special causes (variations with identifiable roots). Control charts signal presence of assignable variation.
Benefits of Control Charts:
Productivity improvement
Effective defect prevention
Avoidance of unnecessary adjustments
Diagnosis and information provision
Process capability information

TQM in Service Industries

Service Quality Determinants:
Reliability, responsiveness, competence, access, courtesy, communication, credibility, security, understanding the customer, tangibles.
Service improvement model: Listen, empathize, apologize, react, and notify.
