Sometimes I think I say that Project Managers can do anything and sometimes the lines between project management and operations management is blurred. This is probably because many of the skills in operations management and project management are complimentary. I have done both functions in this world as a Program Manager. As a Program Manager, you have to be able to manage and mentor Project Managers, but you also have to be able to manage the operations of a business. Project Managers need to understand how a business operates and be willing to jump in a learn about how to make operations more lean and efficient for the business.
