5S method

It aims essentially at eliminating waste through five steps. Seiri means clearing workstations of everything that is not useful, deciding precisely what can stay, what must be kept but moved, and what can be removed. Seiton aims to eliminate everything that lengthens a task and to put simple solutions in place to avoid wasted time. Seiso means cleaning the workstation, again to avoid losing time and to reduce risks to the products. Seiketsu is the step that embeds the new behaviours by writing down simple rules, accessible and understandable by all. Shitsuke covers monitoring, through indicators, how the rules defined in the previous steps are applied and what they produce, in a logic of continuous improvement.
