The Constant Number Method (or Fixed-Value Method) is a Poka Yoke technique making sure the operator

  • makes a certain number of movements and/or
  • uses a fixed number of parts at each step


  • Dispensers feeding the prescribed amount of parts into a part bin such that each cycle results in an empty bin
  • Counters counting the number of operations or parts needed in that step and giving an alert if the actual number differs from the fixed reference amount
