  1. Introduction to Quality Prepared by: Bhakti Joshi Date: December 6, 2012

  2. Evolution of Quality in Businesses • Integrated by Japanese post-World War II to undo cheap imitation products and illiterate workforce • Quality researchers like Juran and Deming helped Japanese companies to introduce quality • By 1960, quality control and management became national preoccupation in Japan • Japan’s imports to US and Europe by late 1960s and 1970s, led to curiosity on quality from Americans and Europeans. • During 1980s, integrating quality in businesses was introduced in US and select European countries • Standardisations for maintaining quality also came around during that time. Example, International StandardisationOrganisation (ISO) 9000 • ISO 9000 prescribes quality management processes and compliances that businesses should must follow subsequent to which businesses acquire ISO 9000 certification

  3. Meaning and Definition of Quality “…a peculiar and essential character” OR “…a degree of excellence” – Merriam-Webster “Quality should be aimed at the needs of the consumer present and future” – “…is a fitness for use” - “…means conformance to requirements” – “…is the totality of features and characteristics of a product or service that bear on its ability to satisfy given needs” – “…is the degree of excellence at an acceptable price and control of variability at an acceptable cost W. Edwards Deming Juran Philip B. Crosby American Society for Quality Broh

  4. Ford Motor Company and Deming 1970s – Mass Production Era 1980s – Competition • Focused on Mass production that led to reduction in short-term costs • Focused on regular inspections on foremen by inspectors who worked against each other • Automated processes were too huge to be shut down • Engineers were overworked that focused on new product development, on-job training and finding/fixing warranty problems • Failure Mode and Effect Analysis (FMEA) was maintained • There were multiple suppliers for the company • Establishment of Ford’s Mission, Values and Guiding Principles that focused on quality instead of profits or technology • Weekly meetings were conducted between senior management and manufacturing unit on quality • Application of Statistical Process Control (SPC) and Quality Function Deployment (QFD) that measured quality or characteristics of products w.r.t. their customers • Training to engineers of SPC and relevant education • Interaction between Engineers and suppliers • Reduce Suppliers base

  5. Ford Company - 1970s – Mass Production Era • Participants – Foreman and Inspectors • Inspectors – Randomly selected parts produced by foremen in each department to check for compliance to specifications • Operations were shut down for repair if parts were rejected • Foremen’s job – To produce and ship as many parts as possible • Were rewarded if foremen refused to shut down a machine for repair if there were defects in parts • Conflict?

  6. Deming and “14 Points” – Point 1 Create constancy of purpose toward improvement of product and service, with the aim to become competitive, stay in business and provide jobs Every business should set their objective, mission and vision that replaces short-term reaction into long-term planning and stability

  7. Deming and “14 Points” – Point 2 Adopt the new philosophy.  We are in a new economic age. Western management must awaken to the challenge, must learn their responsibilities, and take on leadership for change. Management should adopt this philosophy and not expect only the workforce to adopt the same. Businesses need to adopt to changing times and needs and accordingly cannot continue with traditional practises

  8. Deming and “14 Points” – Point 3 Cease dependence on inspection to achieve quality. Eliminate the need for massive inspection by building quality into the product in the first place If variations in a business are reduced then there is no requirement for continuous inspection

  9. Deming and “14 Points” – Point 4 End the practice of awarding business on the basis of a price tag. Instead, minimize total cost. Move towards a single supplier for any one item, on a long-term relationship of loyalty and trust. End practise of awarding to employees basis of price tags (sales targets met in a day, etc.). Multiple suppliers could lead to variations in the overall business

  10. Deming and “14 Points” – Point 5 Improve constantly and forever the system of production and service, to improve quality and productivity, and thus constantly decrease costs. Constantly strive to reduce variation and minimize costs

  11. Deming and “14 Points” – Point 6 Institute training on job The workforce should be adequately trained to avoid any variations

  12. Deming and “14 Points” – Point 7 Institute leadership. The aim of supervision should be to help people and machines and gadgets do a better job. Supervision of management is in need of overhaul, as well as supervision of production workers. There is significant difference between leadership and mere supervision

  13. Deming and “14 Points” – Point 8 Drive out fear, so that everyone may work effectively for the company.. Management should drive out fear so that it prevents the workforce from acting against the interests of the organisation

  14. Deming and “14 Points” – Point 9 Break down barriers between departments. People in research, design, sales, and production must work as a team, in order to foresee problems of production and usage that may be encountered with the product or service. The central focus of the firm should be customer and all departments should work together accordingly

  15. Deming and “14 Points” – Point 10 Eliminate slogans, exhortations, and targets for the work force asking for zero defects and new levels of productivity. Such exhortations only create adversarial relationships, as the bulk of the causes of low quality and low productivity belong to the system and thus lie beyond the power of the work force Deming considers slogans and exhortations as a demotivating factor to employees that may lead to more errors and variations in business

  16. Deming and “14 Points” – Point 11 a. Eliminate work standards (quotas) on the factory floor. Substitute with leadership.b. Eliminate management by objective. Eliminate management by numbers and numerical goals. Instead substitute with leadership. Deming saw standards and targets as factors leading to low productivity

  17. Deming and “14 Points” – Point 12 a. Remove barriers that rob the hourly worker of his right to pride of workmanship. The responsibility of supervisors must be changed from sheer numbers to quality.b. Remove barriers that rob people in management and in engineering of their right to pride of workmanship. This means, inter alia," abolishment of the annual or merit rating and of management by objective Workforce satisfaction is critical

  18. Deming and “14 Points” – Point 13 Institute a vigorous program of education and self-improvement. Workforce motivation and individual growth is essential

  19. Deming and “14 Points” – Point 14 Put everybody in the company to work to accomplish the transformation. The transformation is everybody's job. Adjustment and transformation of management and workforce should be the same
