If you’re interested in improving sales performance the right way rather than throwing the usual quick fixes at it (training, incentives, threats), then Sales and Marketing the Six Sigma Way, by Michael Webb with Tom Gorman, would be worth your investment.
Don’t be put off by the title. Six sigma is not an esoteric, cult-like system for turning your sales force into unthinking automatons. In practical terms, it’s simply the application of scientific method to understanding your sales processes and finding ways to improve it.
In fact, applied to sales, you might be able to think of it as two sigma. In production systems, six sigma is a quality measure that represents only 3.4 defects per million. Most sales organizations would be happy with a defect rate of one sigma, which is almost 700,000 defects per million. That sounds high, but it’s a close rate of 30%. Two sigma would be an improvement of more than 100%, or a close rate of 70%. These numbers show that there is tremendous room for improvement via the application of some of the tools and techniques outlined in this book—without going crazy. As Webb tells us, “When you’ve got a process operating at one sigma, you don’t have to worry about the design of experiments.”
What you do have to worry about is taking a methodological approach to defining, measuring, analyzing, improving and controlling (DMAIC) your sales process.
Yelling at the thermometer
It sounds like common sense, but it’s definitely not common practice in sales leadership, which often approaches sales problems intuitively, or merely throws training or incentives at the problem without taking the time to understand the underlying process. The way that many sales managers operate is like yelling at the thermometer because you don’t like the temperature.
It’s all about the process
Understanding the underlying sales process begins with mapping your customer’s buying process. How do customers become aware of problems and find solutions to them? In every prospect organization, there is an ongoing discussion about their business goals, the need to improve performance, problems that stand in their way, etc. The sales professional’s job is to contribute meaningfully to that conversation, by providing useful information (often in the form of questions, not simply telling) that helps the customer improve their business and personal outcomes.
Too often, sales processes are undefined, or are defined by what salespeople have traditionally done, or are the default process codified in the CRM system you bought. They are not based on how the customer decides and how you can smooth that path for them.
That in turn drives the definition of value in the sales process. Value is defined by the customer, and Webb defines it simply as “anything the customer will take action to obtain.” When you see value this way, you can design your sales process so that it provides that value at the various stages along the customer’s decision process. This provides measurable and meaningful progress, because it’s now measured not by how busy your salespeople are, but by what actions the customers take along the way.
It also lessens resistance. One of the major sources of “defects” in the sales process is customer resistance, and resistance occurs when customers feel like you are doing something to them, which either does not add value to them or forces them to act before they are ready.
The principles of six sigma are:
There is a lot to cover in these six principles, but the book does a good job through detailed case studies that illuminate through example and furnish credibility. In fact, the appendix is worth studying carefully because it has real-life examples of some of the more important tools used. If you specialize in complex B2B sales, the example used can be a little simplistic, but you can extrapolate from there.
A common lament among sales professionals is that sales does not get enough respect as a profession and the major contributor to business success. Perhaps if we can learn to reliably and consistently improve revenue and profits by applying greater rigor to understanding and improving the sales process, that day will come.
 The reason I don’t include the hyperlink to the book on Amazon is that a new copy is priced at over $400! Astute shoppers will be able to pay much less.
