Dimensions of Quality (Cont’d) • Durability - useful life of the product/service • Perceived Quality - indirect evaluation of quality (e.g. reputation) • Serviceability (Service after sale) - handling of customer complaints or checking on customer satisfaction
Service Quality (Garvin) • Time & Timeliness • customer waiting time, completed on time • Completeness • customer gets all they asked for • Courtesy • treatment by employees © 1998 by Prentice-Hall Inc Russell/Taylor Oper Mgt 2/e Ch 3 - 6
Service Quality (cont.) • Consistency-same level of service for all customers • Accessibility & Convenience - ease of obtaining service • Accuracy - performed right every time • Responsiveness - reactions to unusual situations © 1998 by Prentice-Hall Inc Russell/Taylor Oper Mgt 2/e Ch 3 - 7

The Consequences of Poor Quality • Loss of Business • Reputation & Image • Liability • Productivity • Costs
Costs of Quality • Failure Costs - incurred by defective parts/products or faulty services. • Internal • Costs to fix problems detected before product/ service is delivered to the customer. • External • Costs to fix problems detected after product/ service is delivered to the customer.
Costs of Quality (continued) • Appraisal Costs • All product/service inspection costs. • Prevention Costs • All training, planning, customer assessment, process control, and quality improvement costs to prevent defects
Sources of Quality Improvement • Research & Development • Competitors • Customers • Employees
MODERN QUALITY MANAGEMENT • Prevention, not detection or correction • Quality is the concern of all • Suppliers as partners • Continual improvement • Management has ultimate responsibility for quality
Top Management Initiation of the quality management program (goal setting/strategic planning) Middle Management Implementation of the quality management program Supervisory Management Monitoring and controlling quality Production Process/ Operators Management Roles in Achieving Quality

The Deming Prize • Honoring W. Edwards Deming • Japan’s highly coveted award • Main focus on statistical quality control
The ISO 9000/14000 Series Standards • World-wide standards • Registration/audits through documentation and on-site assessments • Structural basis for systems • ISO 9000 (Quality Management) • “Euronorms” – doing business internationally • ISO 14000 (Environmental Performance)
Total Quality Management • A philosophy that involves everyone in an organization in the continual quest for quality, with customer satisfaction as the driving force.
The TQM Approach • Focus on the customer • internal and external • Meet/exceed customer needs • Make processes perfect • mistake proof/right 1st time/fail-safing • Measure, measure,measure …Improve, improve, improve • Involve everyone (including external links)
Elements of TQM • Continual Improvement • Competitive Benchmarking • Employee Empowerment • Team Approach • Fact-based decisions • Supplier Quality • Knowledge of Tools • Champions • Quality at the Source
Continuous Improvement • Constant upgrading of processes & products/services • All operations & work units • Other names • Kaizen (Japanese) • Zero-defects • Six sigma © 1984-1994 T/Maker Co.
Benchmarking Finding best practices (anywhere) as standards for performance • Best Practice - Resolving customer complaints • Make it easy to complain • Respond quickly to complaints • Resolve complaints on first contact • Use computers to manage complaints • Recruit the best for customer service jobs
Employee Empowerment • Getting employees involved in process improvements • Know the job • Close to “action” • Techniques • Support/enable workers • Workers make decisions • Build teams & quality circles • Suggestion systems © 1995 Corel Corp.
Six Sigma • Statistical basis (3.4 defects per million opportunities) • Eliminate defects in ALL areas • Management (strong leadership) • Technical (statistics, measurement) • Champions, Black Belts, Green Belts • DMAIC Process • Define, Measure, Analyze, Improve, Control
Obstacles to TQM • No company-wide definition of quality • No strategic plan for change • No customer focus • Poor communication • No empowerment/enablement • Short-term (“quick fix”) mentality • Politics, “turf issues” • No motivation from employees • Inadequate allocation of time to quality • NO LEADERSHIP/COMMITMENT FROM TOP MANAGEMENT
