Customer satisfaction is generally thought to be one of the most important non-financial performance measures that managers in most industries should track.
In a recent CIMA-sponsored research project, my co-authors and I found negative returns to investments in customer satisfaction in the homebuilding industry in the U.S. (in good economic times). After homebuyers were reasonably well satisfied, it was not economically worthwhile to spend more money to make them even more satisfied. The costs exceeded the benefits.
