Graham Jeffery’s Blog

This blog reflects my wide range of interests. I am passionate about helping organisations, large and small, for-profit and not, to improve the quality of their decision making. One area where I can do that is to bring mathematics to modelling the dynamics and uncertainties of the organisation. So you will find here also some practical advice on risk modelling. I have also, in the process of building this website, learned a lot about designing websites and developed a few tools which I am happy to share. Enjoy! And do send me your feedback.

Monday, 10 May 2010

My friend Kimberley responded to my recent blog about voting with this great question. Is voting one of the small set of decisions that is really beyond (or should be) the scope of decision analysis?
