To what extent are our decisions at work based on data and testing, versus hunches and gut feelings? In Experimentation Works, Stefan Thomke argues that the scientific method should drive business decisions and has the potential to improve performance. On this week's episode of The Good Practice Podcast, Ross D is joined by Owen, Ross G and Nicola for the second in our series of bimonthly 'bookclub' episodes. We discuss:  our general impressions of the book the opportunities created by experimentation at work the challenges associated with workplace experiments.

(2013, August). Online controlled experiments at large scale. In Proceedings of the 19th ACM SIGKDD international conference on Knowledge discovery and data mining (pp. 1168-1176).
