5S is a workplace
It is a powerful LEAN manufacturing tool that requires discipline and buy-in from an entire team to reduce waste of motion and increase productivity.
Ascertain what is required and what you can do without and remove unnecessary items.
Place all remaining items in a neat and orderly fashion that's easily accessible.
Clean the workplace of any rubbish, spills, dust and ensure good lightning is in place.
Ensure standards through visual management and carry these through to all areas.
The toughest aspect of any 5S project is to continue to instill good habits.
