I just came across this article discussing "methadolatry" and although the author is discussing modelling and simulations, I think a lot of his insights could be applied in business planning. http://www.palgrave-journals.com/jos/journal/v2/n3/full/jos20087a.html
I love the sections entitled Methodolatry, the Dead fish fallacy, and the Jehova problem (6-8), especially the stuff in each section written under "The motivation".
I will be expanding on these thoughts in the near future.... Something about their impacts on the culture of work and employee engagement. Stay tuned.
