Net-promoter nonsense

Posted by:

Recently talked with 3 sector-leading firms obsessed with their NP score – the % of customers who are Promoters minus the % who are Detractors. Having more people like you than not is for sure “a good thing”, and NPS advocates like to point out that firms with a high score out-perform others (never mind how the causality actually works, or what to do with it!).

But others already saw that it’s badly flawed, with illogical reasoning and a disconnect from what really matters. First, ...

Posted by:

Is strategy, like economics “pre-science, like astronomy before Copernicus and Galileo.” (Steve Keen: Debunking Economics )?

Revolt of Economics students

Posted by:

See Teaching Economics after the Crisis.  J-C Trichet: ECB President “As a policy-maker, I felt abandoned by conventional tools.” (2010).

This may be mostly about macro-economics, but reflects fundamental inadequacies in the underlying science that afflict micro-economics and have poisoned fundamental ideas in strategy. Even the most basic tools, such as the PQ demand-curve, are hopelessly unrealistic depictions of real-world mechanisms, and attempts to adapt them end up like trying to squeeze Cinderella’s ugly sisters’ foot into a dainty shoe. Standard economic models do not deal ...
