According to Martyn Christian, prior to 2002, FileNet had a fragmented approach to the customer, with no measurement of customer advocacy. Between 2002 and 2006, FileNet improved their NPS score from -6.3 to +20; an increase of over 26 points! How did they accomplish such a feat? By creating a customer-centric culture...
They created a Customer Loyalty Council led by Martyn, the company's chief marketing officer, and including the lead executives from all departments. While other companies focused on financial results primarily, FileNet kicked off each week with a Monday morning meeting focused on customers! They wrote up all the improvement efforts they completed in response to customer feedback (32 in all) and shared the document with customers and prospects as sales collateral! They even did the previously-unthinkable: they had software developers call actual customers on the phone to hear the feedback directly!
The result is such fierce customer advocacy that FileNet has won business away from competitors despite earning a substantial price premium. That premium is called the value of customer loyalty.
An even bigger payoff came last October 12 when IBM paid $1.6 billion to acquire FileNet!
