About WoMI

It’s time for customer metrics to evolve.

The science of measurement may seem static, but in reality it is always evolving. For many organizations, the Net Promoter Score® (NPS®) is a modern-day standard for measuring word-of-mouth behavior.

NPS has enjoyed widespread adoption because it is a simple tool that is readily understandable to internal and external stakeholders. But there’s a problem: NPS is not an accurate measure of word-of-mouth or customer satisfaction because NPS fails to measure how likely or unlikely someone is to recommend or detract.

In today’s social media world, word-of-mouth velocity has increased exponentially, and organizations need more depth and precision than NPS can provide to make valid business decisions.

Our research shows that people NPS labels “detractors” do not always detract, and “promoters” do not always promote. More specifically, new research shows NPS overstates detractors by an average of 260-270%. And because NPS overstates detractors by a very wide margin, many organizations are making customer experience-related business decisions based on an inaccurate metric. In order to make valid business decisions, organizations need more depth and precision than NPS can provide.

It’s time for WoMI℠ – The Word of Mouth Index from ForeSee.

WoMI is a new word-of-mouth metric that helps organizations build on the strengths of NPS while achieving more accuracy and precision. ForeSee tested and refined WoMI over a two-year period with more than 300 companies and through nearly 1.5 million customer surveys. The result was a much deeper and more precise categorization of active promoters and detractors than is possible with NPS, while still preserving NPS-caliber ease-of-use and understanding. WoMI does this by augmenting the NPS “How likely are you to recommend?” approach with a second question: “How likely are you to discourage others from doing business with this company?” WoMI then subtracts the percentage of 9 and 10 ratings from “likelihood to discourage” from the percentage of 9 and 10 ratings from “likelihood to recommend” to arrive at the balanced and accurate WoMI score:

WoMI vs NPS True Promoters and True Detractors

By incorporating both positive and negative word-of-mouth by asking questions focused on each, WoMI more accurately represents the difference between the proportions of consumers who report being highly likely to promote or detract via word-of-mouth.

WoMI offers more sophisticated analytics to understand what consumers want and where to allocate resources. Like NPS, it is a single number that is easily shared with business leaders, enabling executives to manage the customer experience across the organization as part of a comprehensive measurement system. And like NPS, organizations need to understand that WoMI is just one metric within the customer satisfaction ecosystem.

Evolve your analytics. Improve the customer experience.

Word-of-mouth recommendations are an outcome of customer satisfaction, not a driver of satisfaction. To stand out in today’s high-volume word-of-mouth climate, organizations seeking to differentiate through a superior customer experience need to focus on improving positive word-of-mouth and decreasing negative word-of-mouth. To do that successfully, they must measure the drivers of the satisfaction of the customer experience using a methodology that can prioritize improvements and investments. No single question, or even three or four questions, will be able to capture all of the robust, actionable customer experience data organizations need to make improvements on a strategic, tactical, and operational level.

Still, organizations will continue to use word-of-mouth measurement as a defining satisfaction metric, because it is easy to implement, share and understand. Given this reality, it is important for organizations to adopt measurement systems that provide an accurate picture of the world. WoMI is the first measurement that combines the simplicity of NPS with the accuracy executives need to make sound business decisions – making it the first word-of-mouth measurement worthy of being a standard KPI on executive dashboards.
