All business, from networking to negotiating, involves people interacting. Not just understanding but being able to lead and manage that interaction is crucial to business success.
	Ideas are at the root of everything, but there are many, many more good ideas than profitable ones.  Turning a good concept into a successful business requires connections.
	Products and services don't sell themselves however good they or the provider are.  Not just access to the right individuals but  good marketing communication is essential to give credibility.
	Companies are a collection of resources and people, inevitably limited.  Not having or being able to afford a specific capability can be addressed by access to external resources or training.
