Total Quality Management (TQM)

-A management philosophy directed at improving customer satisfaction while promoting positive change and an effective cultural environment for continuous improvement of all organizational aspects -helps the organization focus on customers by identifying and satisfying their needs and expectations.

Quality Assurance (QA)

-A procedure that defines and ensures maintenance within prescribed tolerances for a product or service -Began in the 1970's -Output oriented -Define measurable quality standards and put controls in place to ensure standards are met -Measurement of performance compares actual results to standards -Reactive process -It's predicted on follow-up and inspection and finding error after the fact

Pareto Analysis

-Analysis that focuses on the most important causes to solve problems -80/20 rule: 80% of given outcome typically results from 20% of an input -Example: 80% of sales come from 20% of the customers Focus on these few vital causes

Customer (and types of customers)

-Anyone affected by a product or service -External customers: Don't belong to the organization i.e. Buy pizza from a pizza joint -Internal customer: Belong to organization i.e. Employees and suppliers

What does the ASQ suggest about quality?

-Quality isn't a program; it's an approach to business -Quality is defined by the customer through his/her satisfaction -Quality is aimed at performance excellence; anything less is an opportunity for improvement -Quality increases customer satisfaction, reduces cycle times and costs, and eliminates errors and reworks

Reengineering

-Radical redesign of business processes for dramatic improvement -Focus = improving the process that are core to a business -Process defines as "a complete end-to-end set of activities that together create value for a customer." (Foodservice model: Inputs → Outputs)

EXTERNAL RECOGNITION OF QUALITY: Malcolm Baldridge National Quality Award (1987)

-Recognized companies for their achievements in quality and performance -Promotes sharing info on successful performance strategies -Up to 3 awards given in 5 categories: Manufacturing Service Small business Education Health Care

Reengineering example (taco bell)

-Reengineered process for preparing food -Before 30% floor space for customer seating → 70% -↓ labor needs by 15 hrs/day -↑ capacity of kitchen from $400/hr to $1500/hr -Grew from $500 million company to $3 billion in 10 years

14-Point System To Increase Quality (Deming, 1986)

1) Create consistency of purpose toward improvement of quality and services. 2) Adopt the new philosophy of quality. 3) Cease dependence on inspection to achieve quality. 4) End the practice of choosing suppliers based solely on price. 5) Improve constantly and forever the production and service systems. 6) Institute excessive training on the job. 7) Shift focus from production numbers to quality. 8) Drive out fear. 9) Break down barriers among departments. 10) Eliminate slogans and targets for the workplace. 11) Eliminate numeric quotas for the workplace. 12) Remove barriers that rob employees of pride or workmanship and eliminate annual rating or merit systems. 13) Institute a vigorous program of education and self-improvement for everyone. 14) Make sure everyone in the company is put to work to accomplish the preceding 13 points.

ISO 9001:2008 = generic management standards divided into 5 broad sections:

1) General Requirements for the Quality Management System 2) Management Responsibilities for Quality Policies and Customer Focus and Satisfaction 3) Resource Management 4) Product Realization 5) Measurement, Analysis, and Continual Improvement

The problem: Not enough food on the school serving line Draw a fishbone diagram to identify possible causes of being short of food on the school serving line (the effect)

Environment: Huge increase in students b/c nearby school had to close down Materials: Not enough food ordered from vendor Methods: Portion sizes too large Equipment: Limited number of stoves/ovens, and convenience appliances (food processors, choppers, etc) People: Short staffed Other: Vendor delivered spoiled food

Typical steps of TQM

May be multiple factors leading to a problem May have multiple solutions to solve a problem --> have employees weigh in

US General Accounting Office Study (1994): Companies using TQM practices vs those who did not had: -Higher profitability -Greater customer satisfaction -Better employee relations -Increased market share

The problem: The coffee is too cold Using the root cause analysis, determine what is the problem (you will need to make up a scenario using a series of "why" questions)

Why is the coffee cold? It was not served right away. Why was it not served right away? The server had too many tables Why did the server have too many tables? Because we were short staffed Why were we short staffed? Because several employees reduced their hours for various reasons (ex: school) Solution: Hire more people, advertise the position. Hire more year-round employees to ensure proper coverage
