Social impact is the effect on people and communities that happens as a result of an action or inaction, an activity, project, programme or policy. 

It is important for every organisation to measure their social impact so they can tell the story of the change they make - their supporters, stakeholders and funders' will want to know this. Social investors want to use their money to create impact so they want to know how investing into your organisation will make a difference. 

These tools and resources are designed to help you to manage, measure and communicate the social impact you create (or will create).

The Outcomes Matrix is a quick and easy tool to help you do just that, and is a good place to start. 

If your organisation offers free tools and resources on impact management for charities and social enterprises, please email with a link to the webpage and, if relevant, we will add to this page.

Impact Management Norms

From 2016 to 2018, the Impact Management Project (IMP) convened a Practitioner Community of over 3,000 enterprises and investors to build global consensus on how we measure, improve and disclose our positive and negative impacts (otherwise known as “impact management”). The resulting consensus (or “norms”) provide a common logic to help enterprises and investors understand their impacts on people and the planet, so that they can reduce the negative and increase the positive. These resources migrated to Impact Frontiers following the IMP’s conclusion in 2021.
