Mistakeproofing or Poka Yoke

To err is human but people can design and make systems that are less error-prone, more fail-safe, and defect-free than many are today. One such lean design practice is called mistakeproofing (poka yoke). It is integral to the Toyota Production System and successfully practiced in numerous industry sectors. Mistakeproofing is not as widely- nor as intentionally practiced in the Architecture-Engineering-Construction (AEC) industry as it could be.

This presentation will present 6 mistakeproofing principles and provide lots of examples for the audience to help classify accordingly. 

Meeting participants should bring their own examples and prepare to present them.
