Working Smarter not just about production

The concept of working smarter is not just about production improvements that help you reduce waste and cost. You can work smarter when it comes to sales, marketing and customer service, too. If you don't have a process for reaching out to existing customers, especially those you just completed work for, you are failing to do something today's best, most successful are doing. So, what are you doing to reach out to existing customers, just to say "thanks" or "how'd we do?" or "how can we do it better?"
