  5. 5. Question <ul><li>Quality is important to German car manufacturers like Volkswagen. </li></ul><ul><li>Describe the factors that Volkswagen would have to consider when assessing if they can provide quality in their operating systems. </li></ul><ul><li>(3 marks) </li></ul>
  6. 6.

  7. 7. Quality <ul><li>Organisations in the UK use a variety of measures to ensure all products and services meet a high level of quality. Include: </li></ul><ul><li>Benchmarking </li></ul><ul><li>Quality control </li></ul><ul><li>Quality assurance </li></ul><ul><li>Quality circles </li></ul><ul><li>Quality management </li></ul><ul><li>British Standards </li></ul>
  8. 8. Benchmarking <ul><li>Process of ‘quality assurance’ </li></ul><ul><li>A method of improving quality of production or service by copying best techniques of organisation viewed as “the best”. </li></ul><ul><li>‘ Best industry standard’ can be identified by asking customers, business analysts or journalists. </li></ul><ul><li>Very motivating for staff </li></ul><ul><li>Can create a culture where continual improvement is standard practice. </li></ul><ul><li>Market leaders may be resistant to provide performance figures for competitors </li></ul><ul><li>Need to continue benchmarking even if they become industry leaders to stay ahead of competitors. </li></ul>
  9. 9. Quality control <ul><li>Historic & reactive method of managing quality – works by failure. </li></ul><ul><li>A sample of raw materials and final product passed through a quality control check. </li></ul><ul><li>Unacceptable products discarded as waste or sent back. </li></ul><ul><li>Ensures substandard products are not sold to customers. </li></ul><ul><li>However, assumes wastage and scrap are inevitable – up to 25% of output can be wasted. </li></ul>
  10. 10. Quality assurance <ul><li>Based on prevention. </li></ul><ul><li>Products checked to ensure they meet agreed quality standards at certain points in the production process. </li></ul><ul><li>Requirements determined in advance, minimising risk of error – possibility of “right first time, every time”. </li></ul><ul><li>All aspects of process looked at to ensure errors don’t occur. </li></ul><ul><li>Known to reduce wastage and scrap to 5% or less. </li></ul>
  11. 11. Question <ul><li>Distinguish between quality control and quality assurance. </li></ul><ul><li>(1 mark) </li></ul><ul><li>Solution </li></ul><ul><li>Quality control is an historic & reactive method of managing quality whereas quality assurance is based on prevention. </li></ul>
  12. 12. Quality circles <ul><li>Originated in Japanese manufacturing industries – Toyota fist to use them in 1950s </li></ul><ul><li>Small groups of workers meet at regular intervals to discuss how improvements can be made to production process. </li></ul><ul><li>Principles: </li></ul><ul><li>No one in production process knows more about problems that might arise than the shop floor workers </li></ul><ul><li>Workers will appreciate and be motivated by opportunity to use knowledge and talents alongside management in problem-solving environment. </li></ul>
  13. 13. Total Quality Management (TQM) <ul><li>Also known as Quality Management (QM) </li></ul><ul><li>System of doing things right the first time – no errors are tolerated! </li></ul><ul><li>All staff involved in ensuring absolute quality of their work. </li></ul><ul><li>Works on principle that the next person in line is your customer or client e.g. next person on factory line. </li></ul><ul><li>Constant striving to improve efficiency of processes and reduction of waste. </li></ul><ul><li>Although initially costly, can reduce wastage to around 3%. </li></ul>
