Six Steps For Streamlining Manufacturing Processes
Mine Production History Data . One of the best ways for manufacturers to streamline processes is to use technology to analyze and measure how much material they used, how much they scraped and how much time they spent on the overall manufacturing process. To start, they should review current bills of materials and routing steps to confirm accuracy.
