Foundation
Visual management is part of the base/foundation of the TPS house.
Visual management systems offer quick and efficient communication that helps to reduce various types of waste.
Jidoka
The Jidoka pillar of the TPM house means quality at the source by identifying or exposing problems to quickly and efficiently find solutions before quality issues arise – visual controls are tools to make this identification process possible.
Culture of quality
Making controls visual helps employees feel involved and empowered because they can see how they affect or are affected by the processes – it puts some power back in their hands.
This involvement helps to build a culture of quality within an organization.
