Mistakeproofing, or as commonly known by the Lean community, poka yoke, is a key element of the Jidoka pillar from the Toyota Production System. Mistakeproofing relates to the practical development and use of creative devices that effectively minimise the chance of making errors, while its importance relies on the prompt identification of mistakes (or inhibiting the occurrence of mistakes at all) in order to avoid rework and other types of waste. Despite being a concept originally defined and applied in the manufacturing context, there are few applications in the construction industry, whereas reports of its use within the building design domain are uncommon.
