Impact measurement, evaluation and data
Whether you’re a business, charity or funder, impact measurement and evaluation is all about helping you improve the good work you’re doing. 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.
