The business development process is customized to each specific opportunity.
In developing a game plan for a specific opportunity, the most important thing to calibrate is to align what you are communicating to what the buyer needs to hear at that specific stage. Misalignment of your selling content with buyer needs at that stage not only fails to effectively capitalize on each stage, but also shows the client a lack of understanding about what they want and need (something that hurts your perception as customer service focused.)
