  • counting
  • moving things around
  • searching for things
  • handling customer complaints
  • retyping a letter

  • Future of company depends on quality

Is applicable to every organisation

TQM helps companies to:

  • Focus clearly on the needs of their markets
  • Achieve a top quality performance in all areas, not just in product or service quality
  • Operate the simple procedures necessary for the achievement of quality performance
  • Develop supply chain links, develop internal and external suppliers
  • Critically and continually examine all processes to remove non--productive activites and wastes
  • Develop a effective competitive strategy
  • Never ending improvements
