Chapter 3: Exploring the problem with data

One of the best ways of understanding a specific problem in a particular context, and identifying who needs to do what when and where, is to look at the data. Practitioners often have more data than they realise, or they may not use their data in a way that really helps them explore the problem. Often, we assume we know the scale or cause of an issue. However, our understanding may be inaccurate or biased. Numbers have a great way of taking assumptions out of a problem.
