Quality • Defining Quality • The totality of features and characteristics of a product or service that bears on its ability to satisfy stated or implied needs (American Society for Quality) • Different Views • User-based: better performance, more features • Manufacturing-based: conformance to standards, making it right the first time • Product-based: specific and measurable attributes of the product MIS 373: Basic Operations Management
Quality Management • Quality • The ability of a product or service to consistently meet or exceed customer expectations • For a decade or so, quality was an important focal point in business. After a while, this emphasis began to fade as other concerns took precedence • There has been a recent resurgence in attention to quality given recent experiences with the costs and adverse attention associated with highly visible quality failures: • Auto recalls • Toys • Produce • Dog food • Pharmaceuticals MIS 373: Basic Operations Management
Sales Gains via • Improved response • Flexible pricing • Improved reputation Improved Quality Increased Profits Reduced Costs via • Increased productivity • Lower rework and scrap costs • Lower warranty costs Two Ways Quality Improves Profitability MIS 373: Basic Operations Management
Dimensions of Product Quality • Performance—main characteristics of the product • Aesthetics—appearance, feel, smell, taste • Special features—extra characteristics • Conformance—how well the product conforms to design specifications • Reliability—consistency of performance • Durability—the useful life of the product • Perceived quality—indirect evaluation of quality • Servicebility—handling of complaints or repairs • Consistency—quality doesn't vary. MIS 373: Basic Operations Management
Dimensions of Service Quality • Convenience—the availability and accessibility of the service • Reliability—ability to perform a service dependably, consistently, and accurately • Responsiveness—willingness to help customers in unusual situations and to deal with problems • Time—the speed with which the service is delivered • Assurance—knowledge exhibited by personnel and their ability to convey trust and confidence • Courtesy—the way customers are treated by employees • Tangibles—the physical appearance of facilities, equipment, personnel, and communication materials • Consistency—the ability to provide the same level of good quality repeatedly • Expectations—Meet (or exceed) customer expectations.

Benefits of Good Quality • Enhanced reputation for quality • Ability to command premium prices • Increased market share • Greater customer loyalty • Lower liability costs • Fewer production or service problems • Lower production costs • Higher profits MIS 373: Basic Operations Management
The Consequences of Poor Quality • Loss of business • Liability • Productivity • Costs (e.g., repair, replacement) MIS 373: Basic Operations Management
If quality is so important, why some (if not most) companies are reluctant to pursue high(er) quality?
Costs of Quality • Prevention Costs • Cost of preventing defects from occurring • Planning, administration, working with vendors, training, quality assurance, design and production. • Appraisal Costs • Costs of activities designed to ensure quality or uncover defects • Inspectors, testing, test equipment, labs, quality audits, quality control, field testing • 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 MIS 373: Basic Operations Management

Responsibility for Quality • Everyone in the organization has some responsibility for quality, but certain areas of the organization are involved in activities that make them key areas of responsibility. • Top management • Design • Procurement • Production/operations • Quality assurance • Packaging and shipping • Marketing and sales • Customer service MIS 373: Basic Operations Management
Ethics and Quality • Substandard work • Defective products • Substandard service • Poor designs • Shoddy workmanship • Substandard parts and materials Having knowledge of this and failing to correct and report it in a timely manner is unethical. MIS 373: Basic Operations Management
Case • Toyota settles with government for $1.2 billion in recall probe (washingtonpost.com 3/19/14) • In 2009, the driver of a borrowed Lexus — made by Toyota — was unable to stop the vehicle as it careened off the highway at 120 miles per hour, killing three people. “There’s no brakes…Hold on and pray,” one of the passengers said to a 911 operator. • Toyota Motor Corp. has agreed to a $1.2 billion settlement to end a U.S. Justice Department criminal probe into its handling of safety problems, Attorney General Eric Holder announced. • “The $1.2 billion payment represents the largest criminal penalty imposed on a car company in U.S. history,” Holder said in a statement. “This is appropriate given the extent of the deception carried out by Toyota in this case. Put simply, Toyota’s conduct was shameful,” Holder said.

Total Quality Management • A philosophy that involves everyone in an organization in a continual effort to improve quality and achieve customer satisfaction. • The methods for implementing this approach come from the teachings of such quality leaders as Philip B. Crosby, W. Edwards Deming, Armand V. Feigenbaum, Kaoru Ishikawa, and Joseph M. Juran. MIS 373: Basic Operations Management
Total Quality Management • The Primary Elements of TQM • Customer-focused • Total employee involvement • Process-centered • Integrated system • Strategic and systematic approach • Continual improvement • Fact-based decision making • Communications MIS 373: Basic Operations Management

Total Quality Management • Implementing a Total Quality Management System • Top management learns about and decides to commit to TQM. TQM is identified as one of the organization’s strategies. • The organization assessescurrent culture, customer satisfaction, and quality management systems. • Top management identifies core values and principles to be used, and communicates them. • A TQM master plan is developed on the basis of steps 1, 2, and 3. • The organization identifies and prioritizes customer demands and aligns products and services to meet those demands. • Management maps the critical processes through which the organization meets its customers’ needs. • Management oversees the formation of teams for process improvement efforts. • The momentum of the TQM effort is managed by the steering committee. • Managers contribute individually to the effort through planning, training, coaching, or other methods. • Daily process management and standardization take place. • Progress is evaluatedand the plan is revisedas needed. • Constant employee awareness and feedback on status are provided and a reward/recognition process is established.

Basic Quality Tools • Flowcharts. A flowchart is a visual representation of a process. As a problem-solving tool, a flowchart can help investigators in identifying possible points in a process where problems occur. • Check Sheets. A check sheet is a simple tool frequently used for problem identification. Check sheets provide a format that enables users to record and organize data in a way that facilitates collection and analysis. • Histograms. A histogram can be useful in getting a sense of the distribution of observed values. • Pareto Analysis. Pareto analysis is a technique for focusing attention on the most important problem areas. • Scatter Diagrams. A scatter diagram can be useful in deciding if there is a correlation between the values of two variables. • Cause-and-Effect Diagrams. A cause-and-effect diagram offers a structured approach to the search for the possible cause(s) of a problem. • Run Charts. A run chart can be used to track the values of a variable over time. This can aid in identifying trends or other patterns that may be occurring. • Control Charts. A control chart can be used to monitor a process to see if the process output is random. It can help detect the presence of correctable causes of variation. MIS 373: Basic Operations Management
