How Social Innovators Measure and Optimise Impact
For social innovators, impact is not just an outcome – it is the reason their projects exist. Unlike commercial businesses, which can often measure success through revenue or profit, social innovations are judged by the difference they make in people’s lives, communities, and society.
That raises an important question: how do you measure change? The projects in the Social Innovation Match database show that impact is not something that can be taken for granted. It needs to be defined, measured, and continuously reviewed. Only then can social innovators understand what is working, what is not, and how their projects can create even greater value.
Defining your purpose
Impact cannot be measured without first defining what success looks like. Social innovators therefore need a clear understanding of the change they want to create and the indicators that will show whether they are making progress.
All the projects featured in SIM began with an identified societal need and a clearly defined purpose.
For Re(ad)dress – enter the change, the purpose is to introduce “the thought of reorientation or to achieve a sustainable transition within the labour market for the target group”, namely sex workers.
For Demografieberatung Digi+, the goal is to achieve “sustainable improvements in companies’ ability to manage demographic and digital change while maintaining the workability and employability of employees, especially those aged 45+”.
Social, environmental and economic impact
Once a purpose has been defined, projects can identify the specific forms of impact that contribute to achieving it.
For the Reminiscence with Museum project, impact is defined as “a measurable improvement in the quality of life and emotional well-being”. However, the project’s ambitions go beyond individual outcomes. It also seeks to change how dementia is perceived, moving from a stigmatised medical diagnosis to a condition that can be managed with dignity through cultural and sensory engagement. Its long-term goal is to integrate cultural heritage into Hungary’s formal healthcare infrastructure.
In the case of the Croatian circular economy social enterprise proBUDI VJEŠTinu, the overall purpose is to create tangible and lasting benefits for the local community. This translates into impact across three dimensions.
Socially, the project improves participants’ skills, employability, and engagement while strengthening the culture of social entrepreneurship.
Environmentally, it reduces bulky waste through the repair, reuse, and upcycling of wooden and textile products while promoting sustainable consumption habits.
Economically, it creates new local services, generates revenue that is reinvested into community development, and supports local livelihoods.
The project measures not only immediate outputs but also longer-term changes in attitudes towards reuse, circular economy practices, and community collaboration.
Individual, relational and community levels of impact
Some projects define impact across different levels of society.
Ubuntu Schools aims “to bring about sustained change in how young people understand themselves, relate to others, and act within their communities”.
At the individual level, this includes the development of socio-emotional competencies such as self-awareness, emotional regulation, empathy, resilience, and self-confidence.
At the relational level, impact is visible through improved interactions, including greater respect, active listening, reduced conflict, and stronger collaboration.
At the civic and community level, impact can be seen when students demonstrate a sense of purpose, take initiative, and contribute positively to their school or wider community.
At the systemic level, impact is achieved when the methodology influences school culture through educator involvement, integration into school practices, and the creation of a more relational, participatory, and values-driven learning environment.
Learning from your mistakes
Measuring impact is not only about demonstrating success. It is also about identifying what needs to change.
Ubuntu Schools learned that “participation does not naturally lead to engagement. In practice, we learned that students can be present and even active without being genuinely involved. This led us to focus more on the quality of participation and on creating conditions for deeper reflection and ownership.”
The project also discovered that strong or vocal students are not always positive leaders. In some cases, informal leaders contributed to distraction or exclusion. Rather than suppressing these dynamics, the team learned to recognise and redirect influence towards more constructive roles.
Another lesson was that group work is not automatically collaborative. Without structure and support, it can generate conflict, disengagement, or unequal participation. In response, the project became more intentional about defining roles, supporting relational skills, and creating conditions for effective collaboration.
The Reminiscence with Museum project learned that caregivers could not be treated as secondary observers. This led the team to integrate caregivers directly into sessions and provide dedicated training and counselling, recognising that building trust with patients is impossible without supporting those who care for them every day.
proBUDI VJEŠTinu also challenged its initial assumptions. The project found that participants would not automatically engage with circular economy activities simply because they were available. Practical relevance and hands-on learning proved essential for meaningful participation. As a result, the project shifted its focus towards skill-building through direct repair, upcycling, and production activities.
Measuring impact in a meaningful way
The projects in SIM identify four common challenges when measuring impact.
1. Data is often qualitative rather than quantitative
For proBUDI VJEŠTinu, important outcomes include participants’ skill development, motivation, and sense of community. These are much harder to measure than outputs such as the number of repaired items.
To address this challenge, the project combines quantitative data, including participant numbers, training hours, and repaired or upcycled products, with qualitative methods such as interviews, observations, participant feedback, and testimonials.
Similarly, Necto measures outcomes such as stress reduction, resilience, and psychological safety, which are not directly observable.
2. The source of the data is often inconsistent or unreliable
For the Reminiscence with Museum project, one challenge is gathering feedback from people with advanced memory loss who may not be able to complete traditional surveys. This requires the use of proxy reporting and professional observation, supported by specialist training and ongoing consultation with healthcare professionals.
Re(ad)dress – enter the change faced language and cultural barriers that required interpreters.
Ubuntu Schools needed to standardise reporting across different school settings while also addressing participant bias in self-reporting, particularly among younger students. To do this, the project combined self-reported data with observations from educators.
3. It is difficult to demonstrate attribution
Showing that a project directly caused positive change can be challenging.
Necto acknowledges that many external factors influence mental health, including leadership changes, workload, personal circumstances, and wider economic conditions.
As a result, proving that a particular intervention caused a specific outcome is often difficult.
4. Outcomes are often long term
Many social innovation projects focus on changes that take years to emerge. Whether the goal is improved mental health, environmental sustainability, or greater social inclusion, meaningful impact often requires long-term observation.
This creates challenges for projects operating within limited funding periods.
The ALMA project, for example, needed to demonstrate that improvements in confidence, motivation, and employability skills continued after participation. It addressed this through follow-up activities and a focus on intermediate indicators that could signal future progress.
As Necto has observed: “Change takes time!”
