Organizational Buying Center

Explanation:

The Buying Center is a part of the informal organization and involve a bunch of people who have varying influence on the B2B buy decision.

[...] Since the buying center is a concept from the informal organization, it appears as an elephant in the room among groups of B2B marketers, groups of Supply Chain managers and even mixed groups of Buying/Selling managers. Everybody knows about the Buying Center but  there is really no document that lists the members (being informal) . Thus the discussion rarely achieves focus and output about what the Buying/Selling managers can do to address the mostly legitimate concerns  of the members of the Buying Center."
