The Contact Method is a Poka Yoke technique using a part’s physical attributes such as its color, shape, size, dimensions or weight to prevent or detect errors.

Examples:

  • Color-coding for cables and connectors (e.g. between your computer and monitor)
  • Dimension sensors (e.g. a mesh only letting items of a certain size through)
  • Weight sensors (e.g. used to determine whether a product is missing pieces)
