Prospects must be "comfortable" or they never become paying customers.
Your prospects won't tell you if your value proposition is unclear, your message doesn't resonate, or they are unable to readily digest your “story”. But it's proven that they will tell us. And you need this data to “be the best you can be”.
Your sales people can report back to you how they "think" an initial sales call with a prospective client went, but ultimately this is only a best guess - and good businesses don't run on guesswork. Only the prospect can give an honest assessment of how he or she felt about that early contact. Management needs a window into the prospects view of the sales call.
Surveying your initial Face to Face calls gives you a view into:
Is your value proposition crisp, clear, concise
How well your message resonate
Did the prospect digest your offering in the context of their business
