Traditional monitoring and evaluation tends to look at outcomes at the end of a project, but digital work needs live insight as it goes. In this guide, Charlotte Newman sets out a practical way to narrow the huge number of available data points down to 8–10 metrics worth tracking, grouped across quality, reach, engagement and cost, and filtered on a value/effort matrix. There's also advice on bringing the data into a single source of truth and keeping tracking manageable over time. Useful for digital leads, senior managers reporting to funders, and anyone responsible for evaluation in a small charity.
