Marketing and all things related

Today I've been thinking about the definition of marketing developed by the American Marketing Association's (AMA) Board of Directors in 2004.  This definition replaced the longstanding definition that was in place since 1935.  Their current definition of marketing reads:

Marketing is an organizational function and a set of processes for creating, communicating and delivering value to customers and for managing customer relationships in ways that benefit the organization and its stakeholders.

What do you think about this definition?  I don't like it.  No, I don't like it at all.  How do marketers deliver value to customers?  How do marketers manage customer relationships? 

As a marketer, I've always considered my main role to be delivering tools (analytical, creative, etc.) to attract and retain customers thereby facilitating the creation of sales.  Of course, there is a lot more to it than that, but I just don't understand how the AMA's definition describes what marketing truly is. 

I suppose one could argue that the "adding value" part could relate to new product development which certainly falls under the marketing umbrella.  On the same note, the "managing customer relationships" part could relate to delivering product and brand messages.  However, as a marketer, I always left "managing customer relationships" to the customer service department, and as far as I'm concerned, let the finance team add value by coming up with innovative pricing structures (naturally, I'm exaggerating here).  I guess what I'm trying to say is I can see how the AMA's definition loosely relates to marketing, but I don't see how it directly describes what marketers do and what marketing is.  If someone asked me what I do as a marketer, I can guarantee I would not tell them I create, communicate and deliver value to customers and manage customer relationships.  What is your definition of marketing?
