Whether or not you believe in the Net Promoter Score methodology of measuring customer satisfaction, or some other metric that gives you a sense of your customer's propensity to be an evangelist for your brand, if you are the steward of your company's customer relationship, you need to ask yourself, "Have you created a golden rule culture?"
What is a golden rule culture? It is where your employees treat your prospects and customers as they would like to be treated themselves. (I mean, really, do the people who work at call centers ever want to hear someone tell them when they have a problem, "I am sorry, but that is not a choice in my drop down menu" or "my screen won't let me do that"?)
In a recent post on HBR.org, entitled "The Value in Wowing Your Customers," the author, Fred Reichheld, discusses the value of "intelligent" acts of surprise and delight, those moments of "wow" that individual employees feel empowered to administer and which enable brands to connect with customers on a personal level. The notion is simple to understand, but not always elegantly executed - recognize that your employees are the embodiment of how important your customers are to your business.
Then ask yourself if your employees are in the best position - empowered mentally, technically, and physically - to reflect the level of kindness and empathy your customers should expect?
