Curiosity is a corner-stone of my job, although you may not necessarily expect it. I’ve worked in analytics for over a decade, and increasingly talk to a range of groups about the importance of effective measurement as a key tool in improvement. When I do, the principle that gives rise to the most discussion is to ‘be a data detective’. Apart from using this as an excuse to get a picture of Benedict Cumberbatch on the screen, this means look deeper. Don’t limit yourself to what you see at first. Question everything.
