What is social impact measurement?
According to the International Association of Impact Assessment it is “the process of analysing, monitoring and managing the intended and unintended social consequences, both positive and negative, of planned interventions (policies, programs, plans, projects) and any social change processes invoked by those interventions. Its primary purpose is to bring about a more sustainable and equitable biophysical and human environment.
In other words, it is the change that your social enterprises generates in the ecosystem it operates in, being it social, environmental or cultural change. A social enterprise is the same as any other enterprise with regards to economic viability and financial sustainability, but the difference lies in the fact that a social enterprises in intrinsically have the generation of the aforementioned change or impact at the core of their “raison d´etre”. And this adds on another dimension, a social enterprise needs to have a positive impact on social, environmental or cultural level. In this unit we understand that the term “social impact” means any positive impact on society or the people in it and thus both the environmental and cultural aspects are considered to be covered by the term. Only in those cases where a distinction is needed this will be made.
Why is it important
The demand for (social) impact measurement and assessment has been increasing from the side of different types of stakeholders, not only social enterprises. Examples are:
Measuring impact in a proper way is important for all types of enterprises, as it allows to see whether results are obtained and objectives are achieved. And most importantly whether or not this can be directly correlated to the products or services offered by the enterprise.
There are 5 key terms which you should bear in mind:
In evaluating impact based on outcomes, three more adjustments are taken into account:
Most social enterprises consider themselves catalysts for creating social impact. However, many find it difficult to define what the specific impact is and cannot demonstrate evidence of their impact. Due to this some social enterprises find themselves with business and financial constraints, and cannot drill into additional funding as often funders and investors demand evidence. They end up not thinking about their “social impact” and focus merely on survival due to a lack of resources.
How to measure social impact
Before we dive into the different methods to measure (social) impact, you need to be aware that any kind of measure needs proof or evidence. In social impact measurement there are 2 types:
So what are the most commonly used social impact assessment or measurement methods? There are many, and we made a selection of a few. We know the list is not exhaustive and if the ones presented below do not convince you, you can search for other methods.
The advantage of using one of the existing frameworks and not develop your own is that you save time but also many of them provide guidance on how to actually do the measurement. Our 5 picks are:
Social Development Goals Standards
The Standards are organized around four interconnected themes:
In order to select the appropriate indicators for the impact assessment, your company should first choose a combination of indicators that offer a balanced and adequate reflection of the company’s performance and impacts in a given area. This includes considering different types of indicators, expressing inputs, activities, outputs, outcomes and impacts and ensuring a balance between lagging indicators (those that measure outcomes and impacts) and leading indicators (those that predict the outcomes and impacts).
The next action is to identify and collect data for each of the selected business indicators. It is not always possible to collect data directly, because of impacts occurring further up or down the value chain and also the complexity of the value chain. The cost and complexity of measuring must be proportional to the value that measuring helps to create.
Using existing business processes for data collection, for example extracting the required data from purchasing or sales systems, will be more efficient than developing new processes. If the required data is not available through existing systems, other general methods of collecting and aggregating data include field visits, questionnaires, focus groups, interviews and so on.
The full guide on the SDG impact standards can be downloaded here, and includes references to indicators on the 4 areas mentioned above. The guide can be downloaded here: https://sdgimpact.undp.org/assets/SDG-Impact-Standards-for-Enterprises-Version1-0-July-2021.pdf
If you need more support in defining the indicators, the SDG Compass (
www.sdgcompass.org) has developed an inventory of business indicators mapped against the 17 SDGs and their targets. The inventory contains existing business indicators from widely-recognized sources/standards, so you can select the most relevant ones for your enterprise.
Social Return on Investment
SROI is not only a tool to calculate social impact but is also provide a framework to make you think about the social value created by your enterprise. The process to calculate the SROI is just as important, or even more important, than its actual final value. The process (in terms of information, actors, discussions, data, etc.) limits subjectivity and arbitrariness and helps to upfront the complexity of the assessment. Don’t forget, you have to collect information, data and feedback from all the stakeholders you have considered.
SROI can have an evaluative nature, i.e. you measure ex-post the social value of the results you have obtained, or it can have a forecasting nature, i.e. you estimate ex-ante the social value of the expected results.
The steps for building your SROI are:
Here are some techniques that can help you monetize the indicators:
Cost-price based: There are comparable costs or market prices
Value-price based: There are no indications of cost or price
Contingent Evaluation: willingness to pay for goods and services that are priceless (leisure, landscape, need, well-being).
Here is an example of a guide that make SROI accessible to a range of audiences, including those with limited resources: https://commdev.org/pdf/publications/Measuring-Value-A-Guide-to-Social-Return-on-Investment.pdf
Standard GECES and the Theory of Change
The standard was officially adopted by EC in 2014 with the aim of developing a rigorous and systematic methodology to measure the socio-economic benefits created by social enterprises; evidencing how the money invested in social enterprises yields high savings and income; and agreeing upon a European methodology which could be applied across the European social economy. It is a pan-European standard on impact measurement, which aims to enable social ventures to maximise their full potential, being based on a widely recognised flow, known as the Impact Value Chain (also known as the ‘Theory of Change’ or ‘Logic Model’)
GECES divides the measurement into four key elements:
The standard defines 5 steps for social enterprises to implement impact measurement:

Each of the five stages of the process outlined above is relevant to and involves stakeholders at all levels ranging from investors to service-users. In the self-reflective questions we have included a table which guides you to the questions to be answered.
The GECES standard is based on the Theory of Change that refers to the means (or causal chain) by which activities achieve outcomes, and use resources (inputs) in doing that, taking into account variables in the service delivery and the freedom of service-users to choose. It forms both a plan as to how the outcome is to be achieved, and an explanation of how it has occurred (explained after the event).

Global Reporting Initiative
The GRI Standards enable any organization – large or small, private or public – to understand and report on their impacts on the economy, environment and people. They have been designed as modules, to provide an overview of how the organisation manages and achieves its (social) impacts.
The approach has 3 modules
Triple bottom line
The Triple Bottom Line is an accounting framework that incorporates three dimensions of performance: social, environmental and financial. This differs from traditional reporting frameworks as it includes ecological (or environmental) and social measures that can be difficult to assign appropriate means of measurement.
It integrates economic, environmental and social value creation as core to an organisation’s business model. Three categories make up the triple bottom line;
The downside of the framework is that there is no specific method for measuring its impact. However there are several tools you can use to measure each of the 3 Ps mentioned above.
For the “people” the Global Reporting Initiative, provides reference to the social impact of your business, which can be used to assess the impact on this P.
In the same manner the GRI indicators can be used also for the Planet, and in particular with regards to the environmental impact. The most used indicators here are: Renewable energy use and energy consumption (direct and indirect); Amount of material that is recycled; Amount of water withdrawn from local water sources; or Total NOx, SOx, and GHG emissions
Apart from the more traditional profit and business related indicators, there are additional questions relevant to measure the economic sustainability of the enterprise. Examples of such questions are:
The framework is the ideal tool for evaluating company decisions, as by contrasting the decisions not only form the economic (Profit) perspective. Asking yourself what are the consequences of the decision you are taking for your employees, community or suppliers or for the environment or social justice, and have these weigh into the final decision you take, will allow you to be (or become) a sustainable social enterprise.
