Pre-read
Set one focused discussion question, listening task, and rotation rule; arrange an inner circle with an open chair. Prepare real cases, sources, and boundaries.
Time needed
60–120 minutes.
Setup
Create a workspace with Discussion frame · Fishbowl setup · Inner dialogue · Perspective shifts · Review; keep example values separate from live data.
03
Core question
The one question this method answers
How can a focused inner discussion gain diversity through visible observation and governed rotation?
04
Flow
Phases with goal, actions, output and pitfall
Ein kleiner innerer Kreis spricht, während außen zugehört und bei Bedarf Plätze getauscht werden. Dadurch bleiben Argumente hörbar, ohne dass sich viele Stimmen gegenseitig überlagern oder das Gespräch in Nebenpfade zerfasert.
Fishbowl Discussion · working structure
Fictional example
Fictional values are assigned to explicit method fields.
Discussion frame
Clarify the discussion question, listening task, and rotation rule
Question: Should the rental service keep express pickup? Listening task: value, load, and open assumptions.
Fishbowl setup
Form an inner circle with one empty chair and an outer observation circle
Warehouse, Sales, and Support sit inside; a fourth chair remains open for rotation.
Inner dialogue
The inner group discusses while the outer circle listens to the agreed task
Sales names customer value; Warehouse shows 23 minutes of added search time per express case.
Perspective shifts
Outer participants use the empty chair or agreed rotation without taking over
A service agent takes the open chair, adds three lost regular customers, then leaves it again.
Review
Review content insights, tensions, and observations from both circles
Review separates value, process load, and data gap; a pilot with two express windows is considered.
All details are fictional.

Frame
Discussion frame
Goal
Discussion frame: Clarify the discussion question, listening task, and rotation rule.
Inputs for this step
- Set one focused discussion question, listening task, and rotation rule; arrange an inner circle with an open chair.
- Guiding question, visible agenda, work surfaces, timer, and result repository
Actions
- Clarify the discussion question, listening task, and rotation rule.
Output
Discussion frame
Clarify the discussion question, listening task, and rotation rule
Quality check
Are question, listening task, speaking rule, and rotation clear to both circles?
Pitfall
When the listening task and rotation rule stay unclear, the outer circle later does not know what to watch for or when to switch. Explain the discussion question, listening task, and rotation rule for both circles explicitly before starting.
Timing: Use the time needed within the overall frame; close the step only after its check passes.

Circles
Fishbowl setup
Goal
Fishbowl setup: Form an inner circle with one empty chair and an outer observation circle.
Inputs for this step
- Discussion frame
Actions
- Form an inner circle with one empty chair and an outer observation circle.
Output
Fishbowl setup
Form an inner circle with one empty chair and an outer observation circle
Quality check
Does at least one chair remain open for governed perspective shifts?
Pitfall
When no chair stays open, no one from the outer circle can join and the perspective shift stalls. Keep at least one chair in the inner circle consistently open and make the rule visible.
Timing: Use the time needed within the overall frame; close the step only after its check passes.
- 3
Dialogue
Inner dialogue
Goal
Inner dialogue: The inner group discusses while the outer circle listens to the agreed task.
Inputs for this step
- Fishbowl setup
Actions
- The inner group discusses while the outer circle listens to the agreed task.
Output
Inner dialogue
The inner group discusses while the outer circle listens to the agreed task
Quality check
Does the inner circle discuss while the outer circle listens to the agreed task?
Pitfall
When the outer circle joins the discussion or the inner circle keeps glancing at it, the role separation blurs. Actively enforce the role separation: the inner circle discusses, the outer circle listens according to its task.
Timing: Use the time needed within the overall frame; close the step only after its check passes.
- 4
Rotate
Perspective shifts
Goal
Perspective shifts: Outer participants use the empty chair or agreed rotation without taking over.
Inputs for this step
- Inner dialogue
Actions
- Outer participants use the empty chair or agreed rotation without taking over.
Output
Perspective shifts
Outer participants use the empty chair or agreed rotation without taking over
Quality check
Do guests leave the open chair again so more perspectives can enter?
Pitfall
When one person occupies the open chair permanently, they hijack the discussion and block further shifts. Actively prompt them to leave the chair after their contribution so more perspectives can enter.
Timing: Use the time needed within the overall frame; close the step only after its check passes.
- 5
Review
Review
Goal
Review: Review content insights, tensions, and observations from both circles.
Inputs for this step
- Perspective shifts
Actions
- Review content insights, tensions, and observations from both circles.
Output
Review
Review content insights, tensions, and observations from both circles
Quality check
Does the review separate content findings from observations about discussion dynamics?
Pitfall
When the review only assesses the content, observations about group dynamics get lost. Collect content findings separately from observations about discussion dynamics from both circles.
Timing: Use the time needed within the overall frame; close the step only after its check passes.
