Event Storming

使う場面

  • 要件や仕様にイベントの説明が不足している
  • イベント名の命名やイベント/リソースの区別に迷う
  • Event Storming成果物（イベント/コマンド/集約/リードモデル）を整理・追記したい

ルール（要点）

  • イベントはドメインの重要な出来事で、動詞の過去形で表現する
  • イベントはビジネスの重要な振る舞いを表すため、イベント中心に整理する
  • 原則として 1コマンドに対して1イベント とし、1コマンドで複数イベントを生成しない
  • コマンド名の動詞とイベント名の動詞は対応させる（例: AddCartItem → CartItemAdded）
  • 動詞が異なる場合は別イベントとみなし、混同しない（例: AppendCartItem に CartItemAdded を割り当てない）
  • 関係の表現は「R(, )」で整理する

詳細は references/event-storming-notes.md を参照する。

手順（簡潔）

  1. 重要な出来事を列挙し、イベント名を過去形で確定する
  2. 各イベントに対応するコマンドを逆算して決める
  3. イベントを受け取る集約を決め、境界を調整する
  4. クエリで必要なリードモデルを定義する
  5. R(Event, Resource) / R(Event, Event) / R(Resource, Resource) を整理する
  6. イベント/リソースの区別が曖昧なら判定ルールを適用する
