  3. 3. Conformance to specificationsFulfilling Customer NeedsDefinition of quality focuses not merely on the manufacturingprocess but also on the process of arriving at the specifications. NessFitness to useZero defects https://www.facebook.com/ialwaysthinkpr ettythings
  4. 4. Dimensions of QualityPerformance - main characteristics of the product/serviceAesthetics - appearance, feel, smell, tasteConformance - how well product/service conforms to customer’sexpectationsReliability - consistency of performanceFeatures- Additional attributes to enhance the qualityDurability- How long the product lasts before it requires the replacementServiceability- The ease with which the product can be servicedSafety- Assurance to the customer that there are no hazards https://www.facebook.com/ialwaysthinkpr ettythings
  5. 5. Examples of Quality DimensionsDimension (Product) (Service) Automobile Auto Repair1. Performance Everything works, fit & All work done, at agreed finish price Ride, handling, grade of Friendliness, courtesy, materials used Competency, quickness2. Aesthetics Interior design, soft touch Clean work/waiting area3. Special features Gauge/control placement Location, call when ready Cellular phone, CD Computer diagnostics player
  6. 6. Examples of Quality Dimensions (Cont’d)Dimension (Product) (Service) Automobile Auto Repair5. Reliability Infrequency of breakdowns Work done correctly, ready when promised6. Durability Useful life in miles, resistance Work holds up over to rust & corrosion time7. Perceived Top-rated car Award-winning service quality department8. Serviceability Handling of complaints and/or Handling of complaints requests for information
  7. 7. Service Quality• Tangibles• Convenience• Reliability• Responsiveness• Time• Assurance• Courtesy https://www.facebook.com/ialwaysthinkpr ettythings

  10. 10. Costs of Quality Quality Costs Control Costs Failure CostsPrevention Appraisal Internal External https://www.facebook.com/ialwaysthinkpr ettythings
  11. 11. Costs of Quality• Failure Costs - costs incurred by defective parts/products or faulty services.• Internal Failure Costs – Costs incurred to fix problems that are detected before the product/service is delivered to the customer.• External Failure Costs – All costs incurred to fix problems that are detected after the product/service is delivered to the customer. https://www.facebook.com/ialwaysthinkpr ettythings
  12. 12. Costs of Quality (continued)• Appraisal Costs – Costs of activities designed to ensure quality or uncover defects• Prevention Costs – All TQ training, TQ planning, customer assessment, process control, and quality improvement costs to prevent defects from occurring https://www.facebook.com/ialwaysthinkpr ettythings
  13. 13. The Cost of Quality: Sources of Costs  Training  Verification of Design Prevention  Plant and Equipment  Preventing Defects from Happening Maintenance  Qualifying Suppliers  Incoming materials Inspection Appraisal  In-process Inspection  Evaluating Materials and Performance  Final End-item Inspection  Maintenance of test Equipment  Training Internal Failures  Scrap (waste)  Defects that are Discovered In-House  Re-work  Time spent analyzing failures  Tests and re-tests External Failures  Customer Complaints  Defects Discovered by the Customer  Warranty Costs and Field Re-Work  Damaged Image https://www.facebook.com/ialwaysthinkpr ettythings

  19. 19. Cause & Effect Diagram ( Fish Bone Diagram)It is a line diagram that helps understand the causes of quality issues & effect of those causes. It is a simple tool which resembles the shape of a fish’s bone & therefore also called the fish bone diagram.It helps in discovering all possible causes for a particular effect. The effect examined is some troublesome aspect of product or service quality. https://www.facebook.com/ialwaysthinkpr ettythings

  22. 22. SCATTER DIAGRAM• It is figure which helps to visualize the relation between two variables. It helps determine the correlation between two charateristics. The relationship is expressed in terms of scattered points. It only helps in establishing the co- relation eg: The larger the variable X results in lesser Y https://www.facebook.com/ialwaysthinkpr ettythings

  24. 24. CHECK SHEETSThe check sheets contains a number of cells corresponding to different data categories. The Data need not be necessarily be in numerical form. Check sheets may also contain drawings or design to check locations of failures.The check sheet is a very simple tool that facilitates the conversion from data to useful information. https://www.facebook.com/ialwaysthinkpr ettythings
