To cut down on rework and inefficiency in your shop, you must first and foremost use OE quality parts sourced from a reputable distributor or manufacturer. Otherwise, you’re likely to see a host of part and vehicle failures that will aggravate your customers and cut-down on your revenue generating potential. After you’ve sourced the proper parts, you can use 5S to organize your stock room. 5S stands for sort, set in order, shine, standardize, and sustain. Once your stock room contains quality parts that you can find quickly, you’ll reduce rework in your shop.
