The short answer

Start with a decision your team or board needs to make. Define the measures that inform it, document their sources and limits, and show missing data alongside the results. Grant counts and dollars describe activity; they do not by themselves establish community outcomes.

  • Define the question before selecting metrics.
  • Keep activity, outputs, and outcomes distinct.
  • Show reporting periods, coverage, missing data, and limitations.

Worked example · illustrative

Example: uneven reporting coverage

Illustrative scenario: 12 of 20 grantees submitted reports. The board report shows a 60% response rate and summarizes only those 12 submissions. It does not treat the other eight as having zero outcomes or extrapolate results to the entire portfolio.

1. Choose the question the report should answer

A board may need to understand whether a program is reaching its intended partners. A program manager may need to identify overdue reports. These are different questions and should not be buried in one undifferentiated dashboard.

2. Define measures before collecting more data

For each measure, record the unit, population, source, period, and owner. Ask whether the collection burden is proportionate to the decision. A consistent definition is more useful than a large set of ambiguous indicators.

3. Make coverage and limitations visible

State how many records contributed to a result, what is missing, and whether observations can reasonably be compared. Do not add incompatible measures merely because they can fit in the same chart.

  • Distinguish a missing report from a reported zero.

  • Avoid counting the same participant twice when aggregating programs.

  • Explain definition changes before comparing years.

4. End with a decision and an owner

Pair the findings with a short interpretation, the limits of the evidence, and the next action. If the data cannot answer the question, say what information is needed rather than implying certainty.
