Businesses make hundreds or thousands of decisions every year, many of which seem inconsequential. But the smallest details can have business-changing or even business-ending consequences. Here are 11 of my favorites to watch out for:

1. The lowly extension cord. People get cold feet. They get a space heater. They plug it into a two-pronged extension cord. They forget to unplug it when they leave work. That night, while you are sleeping, your entire business burns down. Your brilliant marketing plan, your three-year projections, all of your records, your new product samples … . You get the idea. This is not something that most business owners think about, but insurance companies know that extension cords and space heaters are major fire hazards. It is good practice not to allow any extension cords in your business that aren’t three-pronged.
