In the words of Bill Gates, "Your most unhappy customers are your greatest source of learning." This sage business advice underpins the principle of the Net Promoter Score (NPS)—a customer loyalty metric thought to be a key indicator of a company's relational health and future growth. Increasingly, Fortune 500 executives view NPS as an essential part of their company's Performance Management strategy. This article delves into the composition of NPS and shares best practices for its effective usage as part of a broader Strategic Management repertoire.

The Net Promoter Score is a straightforward method of gauging customer sentiment. Ask customers one simple question: "On a scale of 0 to 10, how likely are you to recommend our company/product/service to a friend or colleague?" Those who respond with a 9 or 10 are "Promoters", 7 or 8 are "Passives", and 0 to 6 are "Detractors". The actual NPS is calculated by subtracting the percentage of Detractors from the percentage of Promoters.

The simplicity and directness of the NPS system make it uniquely actionable: it gives companies the insight they need to improve, and the feedback necessary for actionable Change Management. According to a McKinsey study, a navigation of the customer journey that leads to unsatisfactory experiences can decrease customer-satisfaction scores by almost 20%—a clear risk to future revenue.

Effective use of NPS requires more than just collecting data—it necessitates a proactive approach to Strategy Development. Solicit feedback through various touchpoints, analyze the results and correlate them with other data, such as customer purchase history or demographics. This allows for more precise targeting of improvements.

Ultimately, aiming for an ever-increasing NPS should be woven into a company's Culture of continuous improvement and Operational Excellence. Regularly updating staff training and enhancing service offerings based on customer feedback would contribute to this aim.

While there has been some debate about the correlation between NPS and financial performance, a study by Bain & Company found a strong correlation between high NPS scorers and companies with superior revenue growth. Companies that prioritize customer loyalty and use NPS as a tactic within a broader Digital Transformation effort can often outperform rivals.

• Don't treat NPS as a standalone metric. It's best used as part of a larger, comprehensive dashboard of customer-centric metrics.
• Close the loop. Always follow up with Detractors to understand their concerns and devise solutions. This promotes trust, reduces churn, and might convert them into Promoters.
• Train your team. Ensure your staff understand the NPS procedure and its importance to the company's growth. This boosts staff morale and productivity.

One critical insight provided by a MIT Sloan Management Review is the "diminishing returns" effect. The research found that while increasing customer satisfaction leads to decreased customer churn initially, there comes a point where further increases in satisfaction do not result in lower churn. This is an essential paradigm to understand and employ strategically in relation to NPS to ensure that efforts and resources are deployed in the most effective manner.

Gaining a deep, data-informed understanding of customers via metrics like NPS can be a gateway to greater Business Transformation, Operational Excellence, and ultimately, superior financial performance. Keeping the customer central is critical now, more than ever, in a landscape that is increasingly competitive and rapidly evolving.
