Tom Peters argues that the analyst from hell is the smart complexifier:
Years ago, in my McKinsey days, one of my bosses was bemoaning the help we were getting from an “economic genius.” He said, “Tom, consider a matrix. One axis boils down to ‘simplifier’ vs ‘complexifier.’ The other is ‘smart’ and ‘dumb.’ Thus we are dealing with a 2X2 matrix. The analyst-from-heaven is the ‘smart simplifier.’ The analyst-from hell is ‘smart complexifier.’ He is, in fact, worse that the ‘dumb complexifier,’ who you can simply ignore, and the ‘dumb simplifier’ who might actually be of help.”
