会議メモをコンセプトマップへ:議論を意思決定・担当者・次の行動に変える
会議メモを、判断根拠、リスク、仮説、担当者つきアクションが見えるコンセプトマップへ整理する実践ガイド。
会議で問題になるのは、記録がないことよりも、関係が見えないことです。発言は残っていても、なぜその判断になったのか、どのリスクが計画を変えるのか、誰が次に動くのかが曖昧になります。会議用コンセプトマップは、議論を判断・根拠・仮説・リスク・行動に分けてつなぎます。
Authority references: concept map, meeting minutes, cognitive load.
要約
- D = decision, A = action, R = risk, Q = open question, E = evidence.
- First draft target: within 24 hours.
- Practical size: 12 to 25 nodes for a 30 to 60 minute meeting.
- Useful link verbs: supports, blocks, requires, validates, changes, owns.
“A meeting map is useful when a person who missed the discussion can see the decision, the evidence, and the next owner in 5 minutes.”
— Hommer Zhao, Knowledge Systems Researcher
Workflow
- Capture raw notes first; do not polish layout during the meeting.
- Choose one focus question, such as: What did we decide and why?
- Keep only decisions, evidence, risks, assumptions, actions, and unresolved questions.
- Label every connection with a verb. Avoid vague lines that only mean related.
- Separate facts from assumptions so follow-up work is clear.
- Add one owner and one date to each action node.

| Node | Review question | Common failure | Fast correction |
|---|---|---|---|
| Decision | What changed after the meeting? | choice without reason | connect 2 evidence nodes |
| Evidence | What supports the choice? | opinion treated as fact | add source or metric |
| Risk | What could change the plan? | no owner | create mitigation action |
| Assumption | What still needs testing? | hidden belief | define a simple test |
| Action | Who does what by when? | task without dependency | connect to decision or risk |
“When a meeting map grows past 30 nodes, split it into a decision map and an execution map.”

Templates
Decision map: options, evidence, selected path, risks, and owners.
Risk map: known facts, assumptions, tests, mitigations, and review date.
Stakeholder map: goals, concerns, constraints, trade-offs, agreements, and conflicts.
FAQ
When should the map be created?
Within 24 hours. After 48 hours, small context details become harder to recover.
How many nodes are enough?
Use 12 to 25 nodes for a normal meeting. Split the map after about 30 nodes.
Does this replace formal minutes?
No. Minutes preserve the record; the concept map explains relationships among decisions, evidence, risks, and actions.
Which relationship labels work best?
Use short verbs: supports, blocks, requires, challenges, validates, owns, and changes metric.
How should disagreement be handled?
Create a conflict node, connect it to the affected decision, and assign one person to bring evidence before the next meeting.
“An action is clear only when the map shows which decision it unlocks or which risk it reduces.”
