What is a Lead? What is the process for that lead to become an opportunity? If you were to poll 10, 100, or even 1,000 companies, you would hear a long list of varying definitions, and that’s okay.
If you were to ask the Sales and Marketing teams within those same companies “how does a lead become an opportunity” would they have the same definitions? This is one cause of the misalignment between sales and marketing that can have a real impact on the number of opportunities created AND closed.
