This excellent guide explains a methodology that can help anyone in sales. This sales approach depends essentially on seeing the sale through the customer’s eyes, and involving the customer in designing a solution to his or her own problems. This approach goes against some standard practices in sales, but those standard practices antagonize customers and build distrust. Author Jeff Thull offers helpful reminders on the value of researching individual customers, picking the right entry point to an organization and other best practices. However, he sometimes seems over-enthusiastic and over-optimistic about his system’s infallibility. After all, in some organizations, sales people who tried to follow this methodology would be criticized for failing to meet more conventional targets, such as number of calls per week. This detailed method for conquering many-level, multi-step sales is time and research-intensive, but highly effective. applauds his emphasis on the value of asking and listening instead of speaking. Highly recommended.

But it was only a beginning. Because many sales people now practice it, it isn’t a differentiating approach in itself. Moreover, its emphasis on asking questions and listening for answers implicitly assumes that customers really know what they need. That isn’t always true. Many problems are so complex that customers don’t understand them.
  • The consultant era - In this era, our contemporary era, the salesperson brings the...
