I hope this little quiz creates some positive internal discussion in your shop among your management team. Many shop owners and managers struggle with the basic math to run a business today and I’m trying to point out that we all must continue to learn throughout our entire life. You can’t shut business education down because things change, and so do many business formulas and guidelines that drive bottom-line profitability. The above questions are just the tip of the iceberg and that is why shop owners and managers must continue to learn to work on their business and not just in their business.

The aftermarket is an exciting arena to run a business today. The opportunities to earn excellent net income are enormous to sustain a great career but it takes a great deal of self-discipline to realize those dreams. As I have mentioned before in previous articles, “shop ownership is a position in the business today” and when the owner does not realize this, or accept it, that he or she must be totally accountable in that position, the shop usually has below profitability required to move forward and management just bought themselves a terrible job. Do not become an industry statistic. Understand the math; understand you business.
