Durability - The degree to which the product tolerates stress or trauma without failing Quality was determined who developed the process 6. Serviceability - Refers to characteristics of product related to ease of repair Workers were judged by how much they can produce, not on the quality 7. Aesthetics - Subjective sensory characteristics such as taste, feel, sound, look Division of labor accompanied the Industrial revolution; each worker was then and smell responsible for only a small portion of each product 8.

Joseph M. Juran (1950s) Defined quality as “fitness for use” Developed concept of cost of quality A1 PURPOSE OF QMS Originated Quality Trilogy: Planning, Control, Improvement 4. Armand V. Feigenbaum (1960s) Instrumental in advancing the “cost of Improving processes nonconformance” approach as a reason for Facilitating and identifying training opportunities management to commit to quality Engaging staff 5. Philip B. Crosby (1970s) Coined phrase “Quality is free” A2 BENEFITS OF QMS Introduced concept of zero defects Developed the phrase “Do it right the first time” 6. Kaoru Ishikawa Affect organization’s performance Developed Cause & Effect Diagrams Meet customer’s requirements Identified concept of Internal Customer Meet the organization’s requirements Introduced the concept of “Quality Circles” 7. Genichi Taguchi Focused on product design quality A3 ELEMENTS OF QMS Developed Taguchi loss function 8. Taiichi Ono and Shigeo Shingo Drivers Both developed the philosophy and methods of “Kaizen” Enablers Result Q – Quest for Excellence U – Understanding Customer needs A – Action to achieve customers appreciation A4 STEPS IN IMPLEMENTING QMS L – Leadership determination to be leader 1. DESIGN AND BUILD - development of the structure of QMS, its processes and I – Involving all people plans for implementation. Responsibility of the senior management to ensure T – Team spirit to work for common goal the needs of the organization. Y – Yard stick measure progress 2. DEPLOY - it is best served in a granular fashion. Breaking each process down Quality means staying in business into sub processes. Educating staff on documentation, metrics and training tools. 3.

A1 CONCEPTS OF TQM This includes: Rework, Re-building of tool, Re-testing, Correction of bank statement PREVENTION COST - are associated with design, implementation, maintenance and Produce quality work the first time planning prior to actual operation, in order to avoid defects from happening. The motto is Focus on the customer “Prevention rather than Appraisal” Have a strategic approach to improvement Improve continuously Encourage mutual respect and teamwork It includes: Market research, quality training programs, design review, prevention check and maintenance, supplier evaluation QUALITY ELEMENT TRADITIONAL APPROACH TQM APPRAISAL COST - spent to detect defects to assure conformance to quality standards. Sum up the “cost of checking if things are correct”. Focuses on discovery of defects rather DEFINITION Product-based Customer-based than prevention of defects. DECISION Short-term Long-term Activities involved: Prototype testing, Vendor surveillance, Incoming material inspection, Final inspection, Laboratory testing, Quality audits EMPHASIS Detection Prevention INTERNAL FAILURE COST - costs that occur when results of work fail to reach designated ERRORS Operations Systems quality standards and are detected before transfer to customer. This cost might disappear if no defect is found in the product before dispatching. RESPONSIBILITY Quality control Everyone Activities involved: Cost of rework, scrap, defectives, Re-inspection, re-test to verify PROBLEM SOLVING Managers Teams analysis, Changing of process to correct deficiencies, Lost production MANAGER’S ROLE Plan, assign, control, and Delegate, coach, facilitate, EXTERNAL FAILURE COST - costs that occur when the product or service from a process enforce and mentor fails to reach designated standards, and is not detected until after transfer to the customer.

The arrangement must be orderly and there must be proper communication. - There should be proper process and communication 7. Customer Focus External Customer - one who purchases or uses the product or service, or one who influences the sale of the product or service Internal Customer - every person in a production process is considered a customer operation
