Measuring Change

What a technology, service or programme actually changes, for whom, and through what pathway. Measured with the people it is meant to serve, and reported honestly.

Two linked disciplines: field research (primary contact) and impact measurement (the frame that turns the contact into a defensible reading of what changed).


Three dimensions we measure

Every study sits inside the same frame, so a result in one context can be read against another.

01 · Reach. Who is actually being reached, and who is being missed. The most flattering programme can be reaching the wrong people, or the same people repeatedly, or leaving the hardest-to-reach unmoved.

02 · Depth. How much things actually change for those reached. Income, time, health, opportunity - measured in the units respondents actually use, not the funder's logframe.

03 · Experience. What it is like to be on the receiving end. Friction, unintended effects, and the qualitative texture that numbers cannot carry. Usually where the useful insight lives.

Reach, depth and experience read together give a picture that a self-report or an output count cannot.


What we track

  • Outcomes, not outputs. "Ten workshops delivered" is an output; "the participants can now negotiate a fair price" is an outcome. Only the second earns the word impact.
  • Quality-of-life change. Concrete shifts in income, time, health, safety, learning, autonomy.
  • Distributional effects. Who was reached and who was excluded. Aggregate figures hide this.
  • Unintended effects. In either direction. Often the most important findings.
  • Customer experience. How the intervention feels to use, and what respondents ask to change first.
  • Attribution and additionality. Whether the change happened because of the intervention or alongside it.
  • Sustainability. Whether the benefit persists once the project ends. Only measurable by revisiting.

How we work

  • In-depth interviews. Structured conversations that reach past what happened to why. See the interview guide.
  • Surveys at scale. Short enough to re-run, rich enough to move a decision.
  • Baseline, midline, endline. The before-and-after spine of any impact claim. Uses the impact-tracking template.
  • Observation and on-site work. Some things are only visible in the doing.

Structured enough to compare, rich enough to matter. For why the Lab leads qualitative and quantifies around it, see Qualitative vs Quantitative.


Ethics

Informed, recorded, revocable consent. Anonymisation by default. Sampling, translation and quality control managed end to end. We interview to understand, not to confirm. Full standards on the Field Research page.

Commissioned work belongs to the client and stays private unless they choose to publish. The case studies here are the exceptions.


Who this is for

The Lab is an independent research team, not an advocacy organisation. We do not campaign, endorse products, or accept commissions where a finding is expected in advance. Where a partner's own theory of change is what needs testing, that is a legitimate engagement, and the Lab tests it honestly.
