You are an expert in your field, right? Whether you sell a product or commit to a batch of service offerings, you know your job and you know it well. We're guessing you have some great employees who know their job well too, right? You hired them because of their drive, interest, and possibly knowledge in the field (or you spend plenty of time teaching and training them). So when someone's computer goes down, why should they waste their time trying to fix it?
