Why a framework at all?
A social enterprise says it changes lives. Fine. But how does it show that?
Without a plan, impact measurement turns into a pile of photographs and feel-good stories. The workbook says a guiding framework keeps the work purposeful, strategic and aligned with the organisation's mission. It is a roadmap for measuring and communicating the good an organisation does.
This chapter covers two kinds of tools:
- Thinking frameworks — the Theory of Change and the Logic Model.
- Guidelines and measurement systems — national (NGRBC), from the global investing community (IRIS+, GIIRS, GRI) and from a multilateral agency (UN Global Compact).
Theory of Change versus the Logic Model
Both are used in programme planning, evaluation and implementation. They are related. But the exam tests the differences, and the workbook lays them out in five rows.
| Point of difference | Theory of Change (ToC) | Logic Model |
|---|---|---|
| Philosophical approach | Narrative-driven. Stresses underlying theories, assumptions and causal pathways. Seeks the deeper understanding of the change process and its context | Visually oriented. Focuses on the linear links between inputs, activities, outputs and outcomes. A simplified, linear picture |
| Causality and assumptions | Explicitly highlights causal links. Involves identifying and testing assumptions | Shows cause and effect too, but may not go as deep into theories and assumptions. A more straightforward sequence |
| Flexibility | Seen as more flexible and adaptable. Encourages ongoing reflection, learning and adjustment | Seen as less flexible, often a static picture — though in practice it can be adapted |
| Visual representation | Can be shown visually, but typically uses a narrative or a map | A visual, linear diagram of inputs, activities, outputs and outcomes in sequence |
| Scope of context | Considers the broader context and how external factors influence change | Focuses on the internal components of the programme |
Which one should an organisation use? The workbook's answer is practical. It depends on preferences, the complexity of the programme, and the audience. Some organisations use both to get the strengths of each.
Theory of Change, properly
The workbook gives several definitions. Learn the key phrases:
- A structured thinking process that turns a team's theories about what needs to change, and why, into a "causal pathway".
- It is not a general theory of how change happens. It is specific to the project.
- It is a step-by-step, backwards mapping process. You start from the ultimate vision and work out all the preconditions needed to reach it.
- A structured and systematic approach to link activities to their impact.
- An outcome-based method with a participatory approach. It applies critical thinking to the design, implementation and evaluation of an intervention (citing Serrat, 2017).
Why does it need to be this careful? Because the workbook says social change is not a simple process. It is a composite of cultural, demographic, economic, environmental, political, religious, scientific and technological forces.
The ToC process (Figure 6.1, from UNICEF)
The ToC describes how interventions contribute to a series of results that lead to the final intended impacts. The steps:
- Situation analysis — identify the problem the intervention seeks to address.
- Gather information on input, output, outcome and impact from:
- primary sources — feedback from different stakeholders
- secondary sources — research and documents published by the organisation and others
- Add the contextual factors that help or hinder change, and the assumptions the theory is built on.
The workbook's worked ToC: rural youth jobs
A non-profit tackles youth unemployment in rural areas where 60% of people under 25 are jobless despite a high school education.
- Problem: youth lack technical skills and access to jobs.
- Long-term goal: enable 80% of rural youth (18–25 years) to secure stable, well-paying jobs in five years.
| ToC element | What the workbook lists |
|---|---|
| Inputs | Financial support from donors; partnerships with local businesses and vocational trainers |
| Activities | Design job-oriented vocational training; soft-skills workshops (e.g. interview preparation); facilitate internships |
| Outputs | 1,000 youth trained annually; 50 partnerships with local employers |
| Short-term outcomes | 80% report improved skills; 50% of trainees secure internships |
| Intermediate outcomes | 70% move from internships to permanent roles; employers satisfied with new hires |
| Impact | Higher incomes for rural youth; unemployment reduced by 50% in target areas over five years |
Around the chain sit two columns.
Assumptions — youth are motivated to complete training; the skills match local jobs; businesses will offer internships and hire; donors keep funding; facilities are sufficient; families encourage youth instead of pushing them into low-skilled work.
Risks — low engagement; training content falling behind job-market needs; employer bias or hesitation; funding drying up; gender norms restricting women; political instability, natural disasters or downturns.
Notice that each risk is roughly the mirror image of an assumption. That is the point of writing assumptions down. They are exactly where the plan can break.
Why ToC matters in social impact analysis
The workbook lists four uses:
- Strategic planning — needs, opportunities, the intended situation and how to get there.
- Implementation — to monitor indicators.
- Impact evaluation — to understand the change due to the intervention. The existing ToC can be reviewed and revised to guide data collection, analysis and reporting.
- Impact reporting — a graphical presentation of the process of change and the end result.
In an impact evaluation, a ToC helps identify (citing UNICEF):
- specific evaluation questions, especially where there is no substantive evidence yet
- relevant variables to include in data collection
- intermediate outcomes to use as markers of success when the impact will not occur within the evaluation's time frame
- aspects of implementation, and contextual factors, to examine in data collection and analysis
National Guidelines on Responsible Business Conduct (NGRBC)
The history, as the workbook tells it:
- 2011 — the Ministry of Corporate Affairs issued the National Voluntary Guidelines (NVGs) on the Social, Environmental and Economic Responsibilities of Business.
- Revised in 2015 (per the workbook) to align with international standards and the Sustainable Development Goals (SDGs).
They can be used by all types of business — any size, sector, ownership or structure. Each principle comes with core elements that make it operational.
The nine principles (Table 6.2). Businesses should:
| No. | Principle |
|---|---|
| 1 | Conduct and govern themselves with integrity, in a manner that is ethical, transparent and accountable |
| 2 | Provide goods and services in a manner that is sustainable and safe |
| 3 | Respect and promote the well-being of all employees, including those in their value chains |
| 4 | Respect the interests of, and be responsive to, all stakeholders |
| 5 | Respect and promote human rights |
| 6 | Respect, and make efforts to protect and restore, the environment |
| 7 | When influencing public and regulatory policy, do so responsibly and transparently |
| 8 | Promote inclusive growth and equitable development |
| 9 | Engage with and provide value to their consumers responsibly |
Why were they formed? The workbook says it was a step by the government to meet its international obligations under several treaty bodies. Companies are expected to integrate the core elements into strategy.
The criticism to remember: non-legal enforceability. They are guidelines, not law. So companies also use other ways to capture social impact.
Frameworks from the global investing community
A. IRIS+
- An impact accounting system for impact investors to measure, manage and optimise impact.
- Offered by the Global Impact Investing Network (GIIN).
- Gives generally accepted definitions of impact categories and themes, and core metrics sets by theme — a shared language for describing and comparing impact.
- Because most impact investors focus on the SDGs, its core metrics and catalogue are aligned to the SDGs.
- It measures impact through the Impact Management Project (IMP) and its five dimensions.
The five IMP dimensions (Table 6.3):
| Dimension | The question it asks | Data categories |
|---|---|---|
| WHO | Who experiences the effect, and how underserved are they in relation to the outcome? | Stakeholder type, geographical boundary, baseline level of outcome, stakeholder characteristics |
| HOW MUCH | How much of the effect occurs in the time period? | Scale (number of people experiencing the outcome — social outcomes only), Depth (degree of change), Duration (how long the outcome is experienced) |
| WHAT | What outcomes is the enterprise contributing to, and how important are they? | Outcome level in period, outcome threshold, SDG, importance of outcome to stakeholders |
| CONTRIBUTION | How does the effect compare to what would likely occur anyway? | Contribution to depth and to duration, after factoring in what would otherwise have happened |
| RISK | Which risk factors are significant, and how likely is it that the outcome turns out different? | Type of impact risk, typically one of 10 risk factors |
The 10 risk factors: evidence, external, execution, stakeholder participation, drop-off, unexpected impact, efficiency, contribution, alignment and endurance risk.
B. Global Impact Investing Rating System (GIIRS)
- A comprehensive, transparent system for assessing the social and environmental impact of companies and funds, in developed and emerging markets.
- Its ratings-and-analytics approach is analogous to Morningstar investment rankings and Capital IQ financial analytics.
- The workbook says its methodology has been used by 6,000 companies.
- An online assessment tool offering both company and fund impact ratings.
- Issues a composite score of social and environmental performance. Ratings are comparable across companies and fund sizes.
C. Global Reporting Initiative (GRI)
- An international non-profit, established in 1997 in partnership with the United Nations Environment Programme (UNEP).
- Develops sustainability reporting standards to improve transparency and accountability on economic, environmental and social performance.
- Available to all types of organisations from different sectors.
Three categories of GRI standards:
| Category | What it covers |
|---|---|
| Universal Standards | Apply to all organisations. Critical concepts, how to use the standards, the organisation's policies and activities |
| Sector Standards | Developed for 40 sectors (e.g. agriculture, oil and gas). Sector characteristics, sector-specific impacts and disclosures |
| Topic Standards | Disclosures on specific topics — e.g. health and safety, tax, waste management |
A framework from a multilateral agency: UN Global Compact (UNGC)
UNGC helps companies align strategy and operations with ten principles in four areas, and guides them towards the SDGs.
The workbook's scale figures: over 9,500 companies and 3,000 non-business signatories from over 160 countries.
Its principles come from four sources: the Universal Declaration of Human Rights, the ILO Declaration on Fundamental Principles and Rights at Work, the Rio Declaration on Environment and Development, and the UN Convention against Corruption.
| Area | Principles |
|---|---|
| Human Rights | 1 Support and respect internationally proclaimed human rights. 2 Make sure they are not complicit in human rights abuses |
| Labour | 3 Freedom of association and the right to collective bargaining. 4 Eliminate forced and compulsory labour. 5 Abolish child labour. 6 Eliminate discrimination in employment and occupation |
| Environment | 7 A precautionary approach to environmental challenges. 8 Promote greater environmental responsibility. 9 Develop and spread environmentally friendly technologies |
| Anti-Corruption | 10 Work against corruption in all its forms, including extortion and bribery |
In India: the Global Compact Network India (GCNI) was formed in 2003, registered as a non-profit society. It is the Indian Local Network of the Global Compact, New York, with over 500 business and non-business participants.
Think of it like this
Theory of Change is planning a wedding backwards
A family fixes the wedding date first. Then they work backwards. The hall must be booked three months before. Invitations must go out a month before. The caterer needs a headcount two weeks before.
Every task is a precondition for the final day. Nobody starts by printing cards and hoping a wedding appears.
That is why the workbook calls ToC a backwards mapping process. You start from the ultimate vision and list every precondition needed to reach it. And like a wedding, it is specific to this family — not a general theory of how weddings work.
Logic Model is the recipe card; ToC is grandmother explaining the dal
A recipe card says: soak dal, pressure cook three whistles, add tadka. Clear, linear, easy to follow. That is the Logic Model — inputs, activities, outputs, outcomes in a straight line.
Now ask your grandmother. She says: soak it because the water here is hard; cook it longer in the monsoon; skip the tadka if Nana-ji has acidity. She is telling you the assumptions and the context that make the recipe work or fail.
That is the Theory of Change. Same dish, but it explains why each step leads to the result, and what outside factors can spoil it. Many good cooks keep both — which is exactly what the workbook says some organisations do.
Contribution is the coaching class that claims the topper
A coaching centre puts up a banner with a student who scored 99%. But that student was already scoring 97% before joining.
How much did the coaching actually add? Only the difference between what happened and what would have happened anyway.
That is the CONTRIBUTION dimension of the Impact Management Project. It does not ask how big the result is — that is HOW MUCH. It asks how the effect compares to what would likely occur anyway. A social enterprise, like a coaching class, should only claim the part it caused.
GRI standards are like a school board syllabus
Every Class 11 student studies English — that is common to all. Then a science student takes Physics and Chemistry, and a commerce student takes Accountancy. Inside each subject, there are specific chapters.
GRI works the same way. Universal Standards apply to every organisation. Sector Standards apply by industry — the workbook says 40 sectors like agriculture or oil and gas. Topic Standards cover specific subjects like health and safety, tax or waste management.
When a question says "applicable to all organisations", think of compulsory English: Universal.
GIIRS is the star rating on a food-delivery app
You do not visit every restaurant's kitchen. You look at a star rating that bundles many things into one comparable score.
GIIRS does that for impact. It gives companies and funds a composite score of social and environmental performance, and the scores are comparable across companies and fund sizes. The workbook compares its approach to Morningstar rankings and Capital IQ analytics.
IRIS+ is different. It is not the star rating — it is the shared dictionary of metrics that lets everyone describe impact in the same words.
