01

Prerequisite

What needs to be finished first

Problem, objective, or decision is described enough that the method can be applied to a clear scope.

Without: Without a clear scope, the team gathers material but cannot derive a robust structure or decision.
02

Preparation

What needs to be ready before start

Materials

Working board or document for intervention plan; existing notes, data, decisions, and assumptions; markers for uncertainty, owner, and next steps.

People / roles

Facilitator; functional experts from the affected area; one owner for result and follow-up; a named decider for decisions.

Pre-read

Scope, trigger, known facts, relevant constraints, prior options or events, and desired outcome of the session.

Time needed

2-4 h

Setup

Prepare an empty intervention-plan template. Keep scope and work question visible at the top. Mark each assumption as assumption, not as fact.

03

Core question

The one question this method answers

Which intervention fits problem, target group, behavior, context, and evaluation?

Flow

Marker: Phase

StepDurationActionHint
1Fix scope
10-20 minDefine 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 minGather 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 minFill 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 minMark 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 minDocument decision, experiment, test, measure, or follow-up with owner and date.A solid artifact without a next action is knowledge work without effect.
05

Artifact

What comes out at the end

Form

Intervention plan with trigger, scope, key elements, assumptions, marked gaps, interpretation of outcome, and next step with owner and date.

Versioning / ownership

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.

07

Pitfalls

Recognize symptoms and steer against them

Trap

Scope drifts

Symptom

New topics are constantly added and the artifact loses focus.

What to do

Keep scope visible and park new topics on the parking lot.

Trap

Assumptions become facts

Symptom

Discussion sounds certain even though evidence is missing.

What to do

Mark every uncertain statement and define a validation point.

Trap

Premature solution

Symptom

Team moves to actions after only minutes.

What to do

First complete the structure, then derive options or measures.

Trap

No counter-check

Symptom

Artifact confirms only the preferred hypothesis.

What to do

Ask explicitly for counterexamples, negative branches, or excluded options.

Trap

No owner

Symptom

Outcome is understandable, but no one continues it.

What to do

Document the next step always with owner, date, and success signal.

08

Stop criteria

Done signals checkable in under a minute

Trigger or scope is unclear.
No raw material or no participants with context knowledge is available.
The method is used to legitimize a decision already made.
Key assumptions cannot be discussed openly.
No owner is available for result or follow-up.
