The Five Dimensions of Impact — What, Who, How Much, Contribution, Risk — with scoring rubrics, auto-built data dictionaries, and LP-ready impact reporting
The Five Dimensions of Impact are the framework — What, Who, How Much, Contribution, and Risk — that the Impact Management Project defined to describe any impact completely. What outcome occurs and how important it is; Who experiences it and how underserved they are; How Much happens in scale, depth, and duration; the enterprise's Contribution beyond what would have happened anyway; and the Risk that impact differs from expectation. The five together turn a vague claim into a structured one.
The framework itself is well documented; where organizations get stuck is operating it. Naming the five dimensions in a report is easy. Scoring a real program against them — deciding what evidence each dimension requires, at a level you can actually normalize across a portfolio — is where the framework either becomes measurement or stays a set of section headers.
Key takeaways
The difference between a report that references the Five Dimensions and one that measures against them is whether each dimension is a heading or a defined field. A heading says “Who: underserved youth.” A scored field says “Who: 82 percent of participants below the area median income, verified against a cited source, on a 1–5 underserved-ness rubric applied identically across the portfolio.” Only the second rolls up.
Sopact calls the operational version the Scoring Architecture: each of the five dimensions becomes a data-dictionary field with a rubric and an evidence requirement, auto-drafted from your own theory of change and documents, so a program is scored — not described — against the framework. The practice this sits inside is on the impact measurement page, and the portfolio version on impact measurement and management.
The framework is not Sopact's; it belongs to the Impact Frontiers community that stewards the Impact Management Project, and the metric definitions can be pulled from the IRIS+ catalog. What Sopact adds is the layer that turns either into a scoreable dictionary on one record.
Every dimension has a resolution problem. How Much can be reported as “many people” or as a scale-depth-duration triple with defined units; Contribution can be asserted or estimated against a stated counterfactual; Risk can be a sentence or a typed register. The framework is only as strong as the weakest dimension you can measure consistently, because a portfolio roll-up inherits the loosest definition in it.
This is why adopting the Five Dimensions as a survey or a scorecard, rather than a narrative section, is the operational move. When each dimension is a defined field collected the same way from every program, the score means the same thing across the portfolio; when it is prose, the roll-up is a summary of summaries. Deciding what to measure per dimension is covered on theory of change, and using the score in diligence on impact investing due diligence.
You score against the Five Dimensions by turning each into a defined field with an evidence requirement and a rubric, collecting that evidence on one participant record, and normalizing the rubric across every program so the scores roll up. The framework tells you the five questions; the Scoring Architecture makes each answerable and comparable.
The table pairs each dimension with the question it answers and the evidence a scoreable version requires. Read the last column: it is the difference between a dimension you can put in a report and one you can defend in a diligence meeting.
Each of the Five Dimensions — What, Who, How Much, Contribution, Risk — answers a distinct question and requires distinct evidence to be scored rather than asserted. The last column is what turns the framework into a Scoring Architecture.
| Dimension | Question it answers | Evidence a score requires |
|---|---|---|
| What | What outcome, and how important is it | Defined outcome + stakeholder-rated importance |
| Who | Who experiences it, how underserved | Demographics + a cited underserved-ness benchmark |
| How Much | Scale, depth, duration | Counts, a measured change, and a follow-up window |
| Contribution | Beyond what would have happened anyway | A stated counterfactual or comparison group |
| Risk | That impact differs from expectation | A typed risk register with likelihood and severity |
Read down the last column and the framework stops being five headings: each dimension is a field with an evidence rule and a rubric, collected the same way across every program. That is the Scoring Architecture — the Five Dimensions as a normalized data dictionary rather than a report outline.
A Five Dimensions assessment written once at diligence ages the moment the investment is made. Scoring against the framework continuously — as new stakeholder data arrives — means the How Much and the Risk scores reflect what is actually happening, not what was projected. That is the premise of the Loop, Sopact's method for continuous impact intelligence: collect clean at the source, analyze the moment data arrives, improve while you can still act.
The Loop is also what makes a dimension score defensible. Every rubric score traces back to the stakeholder response and the benchmark behind it, so when an LP questions a Contribution claim, it resolves to its source. That standard has its own chapter in traceability and transparency.

The fastest way to operationalize the framework is to turn one dimension into a scoreable field. Each prompt below pastes into Sopact Sense's Assistant, or reasons through with your team; the arrow above each links the Academy walkthrough that shows the expected output and the tips.
Academy walkthrough → Turn the five dimensions into a dictionary
Turn the Five Dimensions of Impact into a scoreable data dictionary for this program: [PASTE PROGRAM / THEORY OF CHANGE]. For each dimension — What, Who, How Much, Contribution, Risk — give the field name, a one-sentence definition, the evidence it requires, the rubric levels 1-5, and the allowed values. Flag any dimension I cannot yet collect evidence for. Return a table.
Academy walkthrough → Choose the metric per dimension
For each of the Five Dimensions, propose the single best indicator to measure it for this program: [PASTE PROGRAM]. Write each as who is measured / what changes / by when, note whether an IRIS+ metric exists for it, and mark OUTPUT or OUTCOME. Return a table: Dimension / Indicator / IRIS+ ref / Output-Outcome.
Academy walkthrough → Make each dimension defensible
For each dimension score in this assessment, build a source row: the score, the stakeholder responses and benchmark behind it, the counterfactual used for Contribution, and the one-line calculation. If a source is missing, write MISSING SOURCE. Return a table: Dimension / Score / Source / Calculation. Assessment: [PASTE]
Academy walkthrough → Value the How Much
For the How Much dimension of this outcome, propose a defensible value: [PASTE OUTCOME + CONTEXT]. Give the proxy value with its source, a conservative and optimistic range, the deadweight and attribution adjustments that connect to the Contribution dimension, and the case where I should NOT monetize. Cite sources; do not invent them.
Each walkthrough is short and practical: what to do, the prompt to run, the output to expect, and the tips that keep it reliable.
Watch: operationalizing the Five Dimensions of Impact — from framework to a scoreable data dictionary.
The Five Dimensions of Impact — What, Who, How Much, Contribution, and Risk — are the Impact Management Project's framework for describing any impact completely: what outcome occurs and its importance, who experiences it and how underserved they are, how much happens, the contribution beyond business-as-usual, and the risk impact differs from expectation. Sopact operationalizes them as a Scoring Architecture, a scoreable data dictionary rather than five headings.
The Impact Management Project was a consensus-building initiative that defined the Five Dimensions of Impact and is now stewarded by the Impact Frontiers community. It provides the shared language investors and enterprises use to describe and compare impact. Sopact does not replace it; it turns the framework into a Scoring Architecture on one record so the shared language becomes measurable.
Turn each dimension into a defined field with an evidence requirement and a 1-5 rubric, collect that evidence on one participant record, and normalize the rubric across every program so scores roll up. Naming the dimensions is not scoring against them. Sopact auto-drafts the Scoring Architecture from your theory of change, so each dimension becomes a defended score rather than a described one.
The Five Dimensions are the structure — the five questions any impact must answer; IRIS+ is the catalog of standardized metrics you can use to measure them. They are complementary: the dimensions decide what to ask, IRIS+ supplies defined indicators to answer with. Sopact binds IRIS+ metrics into the Scoring Architecture so each dimension is measured with a standard definition.
What needs a defined outcome and its stakeholder-rated importance; Who needs demographics and a cited underserved-ness benchmark; How Much needs scale, a measured change, and a follow-up window; Contribution needs a stated counterfactual or comparison group; Risk needs a typed register with likelihood and severity. Sopact captures each on one record so the dimension is scored, not asserted.
Map each dimension to the fields that evidence it, define each field once with allowed values and a rubric, and build the intake instrument from that dictionary so the evidence arrives scoreable. Sopact auto-drafts this Scoring Architecture from your own documents, so the framework you adopted becomes the survey you collect and the scorecard you report.
Yes, and increasingly they must: as foundations move toward investment-style accountability, a grant portfolio has to report the way an impact fund does. The Five Dimensions give grants and investments a common structure. Sopact scores both on one record, so a foundation's reporting stack can finally match its ambition.
Because the dimensions were used as narrative headings rather than normalized fields, so two programs score How Much or Contribution differently and the portfolio total is a summary of summaries. The framework is only as strong as the loosest definition in it. Sopact's Scoring Architecture normalizes the rubric across programs so the roll-up is a real number.
The Five Dimensions are the framework; impact measurement and management is the full portfolio practice of setting goals, measuring, and acting on them, covered on the impact measurement and management page. Sopact keeps the dimension scores on the same record that drives the wider IMM cycle, so the framework feeds the practice rather than sitting beside it.
Next: run the portfolio practice on the impact measurement and management page, or score in diligence on the impact investing due diligence page.
