This is a really interesting perspective on when it is – and isn’t – sensible to bring digital approaches and expertise into government policy making. Digital has much to offer policy making, but the value of that offer is massively increased if it is made with some humility, recognising the need to understand and add value to the policy making process. There is a refreshing recognition that not all service design (and so even more so, not all policy) is digital and that the contexts and constraints of policy making can be very different from those assumed in agile development and delivery. That isn’t – and shouldn’t be – a return to the view that policy making is so arcane an art that only true initiates should be allowed to do it, or have an opinion on it. It is though a very welcome recognition of the value of an almost anthropological approach – the idea of sending product managers to be participant observers of the policy making world is a particularly good one.
