Can we only learn from businesses that are electrical? Do non electriclal businesses offer any useful knowledge ? One of the most interesting conversations was with a grocery store manager on the subject of loss prevention and shrinkage. At first I did not see how dented cans and out of date milk could relate to my operation . What could a grocery store and an electrical service business have in common most would say nothing but that is not correct both deal with inventory.How many of us consider how much inventory we loose? How many wirenuts end in the trash can,how many receptacles get scuffed up being halled on the truch and how much copper walks off the job. I never gave this much thought until I realized that this was comming right off my bottom line and if I just took a few simple steps I could put these dollars back where they belonged and that was in my pocket.
