Write an impact report

Turn activity data and beneficiary feedback into a report that separates outputs from outcomes and is honest about the gaps.

Yours to copy, change, and make your own.

— THE PROMPT —

Replace every [BRACKETED PLACEHOLDER] with your own material before you send it.

Help me write the impact section of a report for a UK charity.

Audience: [AUDIENCE]
Period covered: [PERIOD]
What we did, with numbers: [OUTPUTS]
What changed as a result, with any evidence: [OUTCOMES AND EVIDENCE]
Beneficiary feedback we have consent to use: [FEEDBACK]
What did not go well: [WHAT DID NOT WORK]
Length: [WORD COUNT]

Structure:
1. Headline: the single most important change this period, in one sentence.
2. What we did: outputs, as figures, briefly. This is not the impact.
3. What changed: outcomes, each tied to the evidence supporting it.
4. What we learned, including what did not work and what we changed because of it.
5. What is next.

Rules:
- Never present an output as an outcome. "We ran 40 sessions" is an output; "31 of 40 participants reported sleeping better" is an outcome. Flag anywhere I have given you an output where an outcome is needed.
- Use only my figures. Do not round, extrapolate, or annualise.
- Where a claimed outcome has no evidence behind it, say so plainly in the text rather than dropping it.
- Use British English.

Finish with the claims a sceptical funder would most want evidence for.
What to fill in
[AUDIENCE]
Who reads this: trustees, a funder, supporters, the public.
[PERIOD]
The period the report covers.
[OUTPUTS]
What you delivered, with the figures exactly as you hold them.
[OUTCOMES AND EVIDENCE]
What changed for people, and what you have that shows it.
[FEEDBACK]
Quotes or survey responses, anonymised, that you may publish.
[WHAT DID NOT WORK]
What underperformed or was dropped, and why.
[WORD COUNT]
Roughly how long the section should be.
— THE HONEST BIT —

Where it shines, and where it falls over.

Works best for
  • Annual reports and trustees' annual reports
  • End-of-grant reports back to a funder
  • Turning a year of monitoring data into something a supporter will read
Get more out of it
  • Give it the bad news too. Reports that admit what did not work read as more credible, and funders notice.
  • Ask it to rewrite your outcomes as a short theory of change. The gaps in your evidence become obvious.
When it fails

The characteristic failure is quiet inflation. Asked for impact, a model will phrase an output as though it were an outcome, attach a cause to a correlation, and smooth over the point where your evidence runs out. Read section 3 line by line and ask of every sentence: what would I show a funder who asked me to prove this?

Numbers are the second risk. Models merge figures, attach them to the wrong period, and helpfully annualise a quarter. Check each one against your source. Nothing identifiable about a beneficiary should go into a public AI tool either, quotes included, unless it is anonymised and you hold consent to publish it.

AI output is a first draft, not a finished product. You are responsible for whatever you send, publish, or decide with it.
