Impact measurement, evaluation and learning
Home » Consulting »
How do I know if I’m making a difference? What should I measure? How can I make the most of data? How can I use data ethically?
Whether you’re a business, charity or funder, impact measurement and evaluation is all about helping you improve the good work you’re doing. By understanding what’s going well, and learning from what’s not, you can take steps to better serve the people and causes you support. What’s more, you can pool insights together through shared impact measurement. This helps you get the bigger picture on what is often a complex story.
You might be just starting out on all this. Or perhaps you need in-depth advice on a specific area, like handling data or conducting qualitative research. Whatever your situation, we have guidance for you.
Our Understanding Impact guide takes you through how to create an impact measurement framework. To dig deeper, we run regular training events, and our consultants can provide independent measurement and evaluation services.
