Let's say you needed to make a major change or addition that would increase productivity like install new equipment or change your POS. What is the best way to lose the least amount of productivity?
You would need to first see which one the mechanics can give you the most productive work. Equipment will increase work productivity if the equipment you have now slows the mechanics by taking longer to do a job. A POS system can help the mechanic if a lot of time is wasted looking up mechanical repairs in books and using paper based products. You may want to install the equipment to increase work production then after profits increase then get the POS system to help everybody.
