In 2015, we explored whether customer experience really matters to business success or whether CX is just the latest hype. Our conclusion: superior CX drives superior revenue growth in industries where customers are free to switch business and competitors deliver a differentiated customer experience.
This year we repeated our study to see if the results held true across an additional year of data. To do that we compared five pairs of publicly traded companies where one company in each of the pairs had a significantly higher score than the other in Forrester’s Customer Experience Index during the period 2010 to 2015. Then we gathered financial data from company SEC filings like Forms 10-K and 10-Q.
The tough part was normalizing the results. We focused on isolating revenue that could be traced directly to consumer behavior; we also backed out revenue from mergers and acquisitions, revenue from sale of assets, and other windfalls.
Once we normalized the revenue data we used it to build models that calculated the compound annual growth rates (CAGR) for the ten companies from 2010 to 2015. We found that the CX leaders in all five pairs of companies outperformed their relative CX laggard counterparts.
In two industries, cable and retail, leaders outperformed laggards by 24 percentage and 26 percentage points, respectively. Even in the industry with the smallest spread, airlines, the CX leader enjoyed a healthy 5 percentage point advantage in global revenue. And when we compared the total growth rate of all CX leaders to that of all CX laggards we saw that the leaders collectively had a 14 percentage point advantage.
