A very useful contribution to the debate surrounding the usefulness/harmfulness of net promoter score. Jeff Sauro transcends the often polemical nature of the debate, by analysing actual research on the effectiveness of net promoter score.
The news still isn’t all that great for proponents of net promoter score. But at the same time, it’s not quite as bad as its detractors make out.
Kudos to Jeff Sauro for doing some actual research on this.
