There is no "I" in sales. You may sell it alone, but in most organizations you need a well oiled operations team to fulfill and/or service what you sell. The best run companies value both sales and operations to exceed customer expectations and adapt to the market demands of the future. So make sure you stop and thank or give a high five or fist bump to the next operations person that helps you succeed at your sales position. It's the right thing to do and after all, you really can't just do it alone.
