Next, you need to tell the story of what actually happened ‘on the ground’. In order to do this, it is first necessary to collect enough information from a wide diversity of sources. Most of the information will come from the team directly involved in opening up the data but you should also look for other sources of information. This can come from your community of data users, field staff, partner organisations, reports or work plans. The best way to collect information is to use different tools, such as interviews, group discussions, and surveys. When you do this, you are better able to identify missing information, and prioritise, filter and organise what you know, according to its relevance.
