Impact measurement and management (IMM) is the systematic practice of collecting evidence of social, environmental, or programmatic change, analyzing what it means, and using those findings to drive investment, allocation, or program decisions.
Two halves, both essential. Measurement asks the "what changed" question: indicators, baselines, stakeholder voice, year-over-year trends. Management asks the "what do we do about it" question: portfolio rebalancing, intervention design, capital allocation, learning loops. Measurement without management is documentation. Management without measurement is guesswork.
The field has settled on a small set of frameworks for organizing the work: IRIS+ for indicators, Five Dimensions for any single impact claim, Theory of Change for the logic that connects activities to outcomes. The frameworks are not the hard part. Connecting them across the investment lifecycle, on the same record, is.
Two halves of one practice
Half 01
Measurement
What changed?
- Indicators and baselines
- Stakeholder voice
- Five Dimensions scoring
- Year-over-year trends
Half 02
Management
What do we do about it?
- Portfolio rebalancing
- Intervention design
- Capital allocation
- Learning loops
Both halves, one connected investee record
