SEIKETSU (Systematize - Conform and Continue)

SEIKETSU is interpreted in two ways. One is that to keep each individual safe, clean, neat and tidy by wearing proper and safe working dresses, using safety glasses, gloves and shoes as well as maintaining a clean, healthy working environment. Another interpretation is to adhere to work on SEIRI, SEIRON and SEISO continually and every day, i.e. systematically observe the above three as a part of the job in the system.

For instance, it is easy to go through the process of SEIRI once a while and make some improvements, but without an effort to continue such activities, the situation will soon be back to where it was started.
