Improving efficiency in your shop is likely one of your top priorities, but executing and making it happen can be challenging. Three tips for reducing waste and enhancing turnaround times in your operations include:  1. Using OE quality after-market parts instead of cheaper imitations. 2. 5S (sort, set in order, shine, standardize, and sustain) and other processes are excellent tools used to organize your shop. 3. Utilize aftermarket manufacturers who offer technical support phone lines. Phone support, in particular, can help your personnel troubleshoot problems and provide a higher quality of service.
