Sharing case studies and customer testimonials is how a sales rep should reinforce elements of the value proposition for the customer. A value proposition is a statement that summarizes how the product can solve the customer's problems, fulfill their needs, and provide them with benefits that outweigh the costs. Case studies and customer testimonials are stories or feedback from existing customers who have used the product and can vouch for its value proposition. Sharing case studies and customer testimonials helps to provide proof points, build trust and credibility, and influence purchase decisions

Revisiting dead opportunities can help to identify if their situation has changed, if their pain points have increased, or if they are more open to considering the product again.
