  9. 9. Lessons learned• It’s the system not the workers• It’s management thinking that designed the system• Arbitrary numerical targets were completely ineffective• Rewarding or punishing the workers had no effect• Rigid and precise procedures are not sufficient to produce quality• Keeping the ‘best’ workers did not work• Management tampering creates more problems than it solves• Posters and slogans are at best useless and can be insulting and create resentment• The biggest source of variation was in the system
  10. 10. Theory of Variation
  11. 11. The First Principle of the Theory of VariationWe Should Expect Things to Vary, They Always Do

  20. 20. “I recently asked a colleague [CIO] whether he wouldprefer to deliver a project somewhat late andoverbudget, but rich with business benefits, or one that ison time and underbudget but of scant value to thebusiness.He thought it was a tough call, and then went for the on-time scenario. Delivering on time and within budget ispart of his IT department’s performance metrics.Chasing after the elusive business value, over which hethought he had little control anyway, is not.” Cutter Sr. Consultant Helen Pukszta
  21. 21. If you give a managera numerical target, he’llmake it, even if he has todestroy the company in the process.
  22. 22. The Third Principle of the Theory of Variation Work on the Causes of Variation,Which are Always Found in the System
  23. 23. Majority of Performance is Down to the System A bad system will defeat a good person every time. System 95% Individual 5%
