How to Calculate a 5S Score

A 5S score is one way to measure a company's lean manufacturing processes. Like all lean manufacturing tools, a 5S score indicates how well the company is allocating its resources. The five S's stand for Sort, Set in Order, Shine, Standardize and Sustain. You can calculate a 5S score in a few straightforward steps.

Create a chart on a blank piece of paper. Use five subheadings: "Sort," "Set in Order," "Shine," "Standardize" and "Sustain." Under each subheading leave enough room to write five questions.

Write five questions under each subheading. The questions will be different depending on what you want to measure. For example, a "sort" question might refer to unnecessary tools being used. A "set in order" question might ask if shelves have markers that indicate where items go. A "shine" question focus on how well a piece of equipment is cleaned. A "standardize" question might ask if procedures are being actively used. A "sustain" question might ask if everyone is properly trained in a procedure. See the "Resources" section for more question examples.

Write a score from 0 to 5 beside each question. The lower the score on a question, the worse the company is doing in that particular area. For example, if the company doesn't use any markings on shelves to indicate where items go, you could give it a 0 score on that question.

Add up the scores to determine an overall 5S score. Some companies will use this number as their final 5S score.

Divide the overall 5S score by the number of questions. For example, if your company has an overall score of 93, you would divide 93 by 25 and get 3.72 on a scale of 5.0.
