Quality Managers are another investment that can pay huge dividends. Quality managers will be responsible for auditing your internal processes and external supplier standards. They will make sure that finished products meet customer requirements before launch.
Having a good quality manager will most certainly save on expediting costs, time on delivery charges, and scrap rates just to name a few.
This will be another role above all else that you will want someone who can work well with a team that has many different personalities. This will really help save your company money it doesn't have to spend.
