Vocabulary Term Definition
5S A targeted list of activities that promotes organization and efficiency in the workplace. The 5S terms are sorting, straightening, shining, standardizing, and sustaining.
5S + 1 A version of the 5S philosophy that includes a sixth "S" for safety. 5S + 1 is used to educate workers on safety issues and to address potential safety hazards.
communications board A method of displaying information about 5S implementation in the workplace. The communications board should be posted in a highly visible area to be viewed by all employees.
ergonomics The study of designing devices to decrease operator discomfort or fatigue and increase productivity. 5S + 1 can address issues of ergonomics.
eye wash station A designated station in an easily accessible area in which employees may flush their eyes with water in the event of an emergency. 5S + 1 ensures that eye wash stations are easy to locate and access.
fire extinguisher A portable device that uses a rapid spray of chemicals to put out small fires. 5S + 1 ensures that fire extinguishers are easy to locate and access.
floor plan A two-dimensional drawing that depicts the arrangement of the workplace. Before and after floor plans are often used to track 5S improvements.
lean manufacturing An approach to manufacturing that seeks to improve product quality and productivity, reduce cost, and eliminate waste. 5S is a lean manufacturing process.
personal protective equipment Any type of safety equipment that workers wear or use to prevent injury in the workplace. 5S + 1 ensures that personal protective equipment is easy to locate and access.
quality An approach to manufacturing that focuses on customer satisfaction. 5S is a philosophy often used to improve product quality.
red tagging A method used in the sorting phase of 5S that involves placing tags on items to designate their status. Red tags indicate that an item should be removed from the work area.
safety The practices and policies that a company puts in place in order to preserve the health and well-being of employees, equipment, and facilities. 5S and 5S + 1 improve workplace safety.
shadow board A device used in the straightening phase of 5S to organize tools and materials. A shadow board contains outlines of designated tools to show where they should be stored.
shining The third phase of 5S. In the shining phase, the work environment is thoroughly cleaned and maintenance tasks are identified.
sorting The first phase of 5S. In the sorting phase, unnecessary clutter is removed from the workplace.
spaghetti chart A two-dimensional drawing, based on a floor plan, that includes lines that track the movement of an employee throughout the work area. Before and after spaghetti charts are often used to track 5S improvements.
standardizing The fourth phase of 5S. In the standardizing phase, methods for maintaining 5S throughout the workplace are identified and documented.
status board A method of tracking 5S improvement and communicating it to employees. A 5S status board often contains before and after floor plans and spaghetti charts.
straightening The second phase of 5S. In the straightening phase, the workplace is organized using techniques such as shadow boards and labeling.
sustaining The fifth phase of 5S. In the sustaining phase, all employees must work together to continue and maintain 5S improvements.
waste Any thing or process that does not add value to a product. The goal of lean manufacturing is to eliminate waste.
