We make decisions, and these decisions make us and our organisations. And in theory, decision-making should be easy: a problem is identified, the decision-makers generate solutions, and choose the optimal one - and powerful mathematical tools are available to facilitate the task.Yet if it is all so simple why do organisations, both private and public sector, keep making mistakes - the results of which are borne by shareholders, employees, taxpayers and ultimately society at large?This guide to decision making. by leading decision science academic Helga Drummond, aims to improve decision-making in organisations.It explores how and why decisions go awry in the first place - and offers practical advice on what decision-makers can do to counter the psychological, social and other forces that can undermine individual judgment and pull organisations off course.Full of examples of good and bad decision-making from around the world, it will make readers think more clearly about decisions big and small.
