Marketing Differ from Project Management

I would respectfully have to differ with you here. I think great marketers can be great project managers, but project managers by definition do not have training in several vitally important aspects of marketing. I say with some related experience - I once had a Project Manager on my staff who was ISO-7000 qualified (the top qualification at the time). She was Fantastic in making sure everything was on track (resources, budgets, critical paths, etc.). She was in no way qualified to be a marketer.

I feel that project Manager executes the directives of the strategy, positioning and marketing plan created by the Marketer, in order to meet the requirements of a particular project. The Marketer makes the requirements of the program; the Project Manager manages the operational, strategic and tactical recommendation rollout and execution.
Marketers think and strategize; Project Managers carry out their programs.

To say that project manager is a generic term that applies to all business areas - building a bridge, implementing an ERP system, overseeing the scientific payload of a space probe, and marketing campaigns. While marketing efforts may require project management, Project Managers (in almost every other field) rarely get involved with marketing.
