Problem, objective, or decision is described enough that the method can be applied to a clear scope.
Intervention Mapping
Prerequisite
What needs to be finished first
Preparation
What needs to be ready before start
Working board or document for intervention plan; existing notes, data, decisions, and assumptions; markers for uncertainty, owner, and next steps.
Facilitator; functional experts from the affected area; one owner for result and follow-up; a named decider for decisions.
Scope, trigger, known facts, relevant constraints, prior options or events, and desired outcome of the session.
2-4 h
Prepare an empty intervention-plan template. Keep scope and work question visible at the top. Mark each assumption as assumption, not as fact.
Core question
The one question this method answers
Which intervention fits problem, target group, behavior, context, and evaluation?
Flow
Marker: Phase
| Step | Duration | Action | Hint |
|---|---|---|---|
1Fix scope | 10-20 min | Define trigger, objective, and boundaries of the analysis. Collect off-topic topics in a parking lot. | A narrow scope produces better outcomes than a complete but diffuse sweep. |
2Collect raw material | 20-40 min | Gather facts, events, options, constraints, or assumptions and make them visible. | Keep facts and interpretations separate. Mark uncertain points instead of smoothing them over. |
3Build structure | 30-60 min | Fill the intervention plan step by step, clarify relationships between elements, and surface contradictions. | Do not evaluate too early. First stabilize structure, then draw conclusions. |
4Review and distill | 20-40 min | Mark gaps, weak assumptions, counterexamples, and critical paths. Check whether the outcome is understandable. | If the logic cannot be explained in two minutes, the artifact is not complete. |
5Define next steps | 15-20 min | Document decision, experiment, test, measure, or follow-up with owner and date. | A solid artifact without a next action is knowledge work without effect. |
Artifact
What comes out at the end
Intervention plan with trigger, scope, key elements, assumptions, marked gaps, interpretation of outcome, and next step with owner and date.
Save artifact with date, scope, and participants. If new evidence arrives, create a new version or change log so decision logic remains traceable.

Concrete filled scenario, fictional example
Intervention Mapping - Onboarding activation of new tenants
Scope: A concrete project area is assessed, not the entire company. Work question: Which intervention fits problem, target group, behavior, context, and evaluation?
Artifact excerpt:
- Fact 1: Current observation is documented and linked to a source.
- Assumption 1: The most important causal relationship is plausible but not yet proven.
- Critical point: An open condition determines whether the preferred direction is sustainable.
Result: The team selects a focused next step with owner and date. Signal: From change intent to program design.
Pitfalls
Recognize symptoms and steer against them
Scope drifts
New topics are constantly added and the artifact loses focus.
Keep scope visible and park new topics on the parking lot.
Assumptions become facts
Discussion sounds certain even though evidence is missing.
Mark every uncertain statement and define a validation point.
Premature solution
Team moves to actions after only minutes.
First complete the structure, then derive options or measures.
No counter-check
Artifact confirms only the preferred hypothesis.
Ask explicitly for counterexamples, negative branches, or excluded options.
No owner
Outcome is understandable, but no one continues it.
Document the next step always with owner, date, and success signal.
Stop criteria
Done signals checkable in under a minute
