Assign someone in each department to take inventory and organize each item in their collective workspace. Go deep in storage or often-overlooked areas to account for every tool, cleaning supply, and product. You may find duplicate items or items that were once useful but no longer serve a purpose. Finally, get rid of things you don’t need and put things you do need in easy-to-find places. Follow the 5S guidelines: sort, set in order, shine, standardize, and sustain.
