In "SPIN Selling," Neil Rackham argues that the key to sales success in complex sales is to build the customer's perception of value through effective questioning early in the sales process.
He disagrees with conventional wisdom that argues that selling is about handling objections and deploying closing techniques. Rackham recommends that reps ask several layers of questions about the customer's problems and get the customer to articulate the importance of solving those problems.
This book is valuable because it highlights the importance of reaching a shared understanding of what the customer needs before launching into a pitch. Great pitches are about connecting the product to needs, not about the product itself.
The Importance of Investigation
Rackham's research shows that, for complex sales, the investigation phase of a deal is the critical determinant of success because the right kind of investigation can build the customer's perception of value.
He recommends that sales reps follow the SPIN questioning framework by asking these four types of questions in the order listed below:
Situation Questions: Background questions about the customer's current state. For example: “How long have you done X?” These are necessary but don't drive sales success on their own.
Problem Questions: Inquiries about difficulties or dissatisfactions. For example: “Is X difficult for you?” These are helpful but aren't the the most important on their own.
Implication Questions: Questions that explore the consequences of problems. For example: “How does X affect your future profitability?” These are powerful because they help customers understand the seriousness and broader impact of their issues.
Need-Payoff Questions: Questions about the value or usefulness of solving a problem. For example: “If we could improve X, how would it help you?” These are the most powerful questions in major sales because they prompt customers to articulate in how your solution would benefit them. They get customers to sell themselves on your solution.
The goal of this questioning sequence is to move from implied needs (general statements of dissatisfaction) to explicit needs (specific statements that show urgency and desire for action).
Tying Benefits to Explicit Needs
Rackham looks at three kinds of points that sales reps often make:
Features: What your product does
Advantages: How your product is better than alternatives
Benefits: Ways you help the customer
He finds that presenting features and advantages, though necessary, isn't enough to drive sales success. Interestingly, he finds that simply presenting benefits also isn't strongly related to sales success.
Instead, the key is to present benefits that are tied directly to explicit needs that the customer has already stated. When customers express these needs themselves during the SPIN questioning process, they take ownership of the solution and become ready to act.
Obtaining Commitment
Traditional closing techniques aren't as important in complex sales as they are in more transactional deals. In fact, Rackham's research found that salespeople who rated closing as highly important actually performed below goal for complex sales.
That said, obtaining commitment matters for driving sales processes forward.
Good salespeople set appropriate objectives for each call and specify them beforehand. They focus on advancing the sale to to a specific next step the next step rather than merely having the vague goal of continuing the conversation.
Four specific actions help salespeople obtain commitment:
Giving proper attention to investigating and demonstrating capability
Checking that key concerns are addressed
Summarizing the benefits before asking for commitment
Proposing a clear and specific commitment to a next step
Conclusion
To implement SPIN Selling, plan ahead. Write down problems that your product solves and draft potential questions that explore those problems. Look for safe ways to practice the investigation techniques and aim to get as much practice as possible.
