Seiri - Throw away all rubbish and unrelated materials in the workplace.
English equivalent: Tidiness
One of the Five S parts.
The first step of "5S", seiri, refers to the act of throwing away all unwanted, unnecessary, and unrelated materials in the workplace. People involved in Seiri must not feel sorry about having to throw away things. The idea is to ensure that everything left in the workplace is related to work. Even the number of necessary items in the workplace must be kept to its absolute minimum. Because of seiri, simplification of tasks, effective use of space, and careful purchase of items follow.
