At Clozd, we’ve noticed that there is one particular thing that carries some extra weight in determining how fast a sales hire ramps: Understanding the reasons why buyers make their buying decision (the criteria they use) and how your company competes on each of those factors. In short, we call it understanding why you win and lose.
Don't rely on your sales team for unbiased feedback about your buyers - they will be wrong more than half the time. For critical feedback about how buyers perceive your business and your offering, go straight to the source. Conduct win loss interviews with the actual buyers at your won and lost accounts.
