Here are a couple of articles I’ve found in the Times newspaper about how NLP is used in business.
Business NLP, Academics and Persuasion Techniques
The first is the usual journalistic pap but does talk about how some companies like Vodaphone and Honda are applying some NLP
The second has a lot more substance and is a mini case study on First Direct and how they have been modelling sales performance.
There are a whole host of ways of using NLP Persuasion Skills in Business from the Persuasion Skills Master Training Programme.
