Once you have designed and implemented an evaluation based on the needs of your social enterprise, you will need to analyse the data you have gathered, and communicate your findings.
If you have collected qualitative data through open-ended survey questions or interviews, you might choose to communicate the findings in written form, by summarising the main themes and providing an illustrative quote or two for each theme. A participant case study might take more of a narrative shape, telling the story of how a participant became involved in your social enterprise, and what has changed for them through their involvement. You might choose to share your qualitative findings in non-written formats, perhaps telling a story through photos, video or animation.
When it comes to communicating numerical data, the right approach will depend on the type of numerical data you have collected, and what the data shows. There are some free online resources available that are created by people with expertise in statistics, data analysis and graphic design that can provide a useful overview of data visualisation. From Data to Viz has an interactive tool that provides general guidance on selecting the right data visualisation approach for your data. Nathan Yau from Flowing Data writes succinctly about how to avoid common pitfalls when charting your data.
Whatever kinds of data you have gathered, being clear about your evaluation purpose and intended audience will help you find fitting ways to communicate your findings.
