プロセスフローチャート設計

業務プロセスを明確な視覚図に変換し、非効率な点を特定して、最適化されたワークフローを設計するためのフレームワークです。

フローチャートの記法

標準記号

FLOWCHART SYMBOL REFERENCE:

  ┌─────────┐
  │ Rectangle│  = Process / Action step
  └─────────┘

  ◇ Diamond    = Decision point (Yes/No, True/False)

  ┌─────────┐
  │/ Parallel/│  = Parallelogram = Input/Output
  └─────────┘

  ( Oval )     = Start / End (Terminal)

  ┌─────────┐
  │ Cylinder │  = Database / Data store
  └─────────┘

ワークフローの最適化

ボトルネックの特定

BOTTLENECK ANALYSIS: [Process Name]

For each step, evaluate:

Step | Duration | Wait Time | Handoff? | Rework Rate | Bottleneck Score
-----|----------|-----------|----------|-------------|------------------
1    | [time]   | [time]    | Yes/No   | [%]         | [1-10]
2    | [time]   | [time]    | Yes/No   | [%]         | [1-10]
3    | [time]   | [time]    | Yes/No   | [%]         | [1-10]

BOTTLENECK SCORING:
  Duration weight:    x3 (longest steps)
  Wait time weight:   x4 (idle time is waste)
  Handoff weight:     x2 (each handoff adds delay and error risk)
  Rework weight:      x5 (rework multiplies all other costs)

  Score = (Duration x 3) + (Wait x 4) + (Handoff x 2) + (Rework x 5)

TOP BOTTLENECKS (highest scores):
  1. Step [N]: [Description] — Score: [X]
     Root cause: [Why this step is slow/problematic]
     Recommendation: [How to fix]

  2. Step [N]: [Description] — Score: [X]
     Root cause: [Why]
     Recommendation: [Fix]

ムダの特定（リーン）

ムダの種類	定義	兆候	解決策
待ち	ステップ間の待機時間	待ち行列、滞留	並列処理、SLA
過剰加工	必要以上の作業	過剰な承認、過剰品質	簡素化、承認者の削減
手戻り	エラーの修正	高い却下率、ループ	エラー防止、検証
動作	不必要な移動	複数のシステム、コンテキストの切り替え	ツールの統合
運搬	情報の不必要な移動	過剰な引き継ぎ	直接ルーティング
在庫	作業の滞留	ステップでの大きな待ち行列	フロー型処理
作りすぎ	必要以上の生産	誰も読まないレポート	需要主導型の出力
欠陥	後工程に流出するエラー	顧客からの苦情	発生源での品質確保

RACI マトリックス

RACI MATRIX: [Process Name]

Task / Step              | Role A | Role B | Role C | Role D
-------------------------|--------|--------|--------|-------
1. [Step name]           | R      | A      | C      | I
2. [Step name]           | I      | R      | A      |
3. [Decision point]      | C      | R      | A      | I
4. [Step name]           | A      | I      | R      |

R = Responsible (does the work)
A = Accountable (approves / owns the outcome)
C = Consulted (provides input before)
I = Informed (notified after)

RULES:
  - Every task has exactly ONE "A"
  - Every task has at least one "R"
  - Minimize C's and I's (reduce communication overhead)
  - "A" should not also be "R" if possible (separation of duties)

自動化の評価

自動化候補のスコアリング

AUTOMATION ASSESSMENT: [Process Name]

For each step, score automation potential:

Step | Repetitive? | Rule-Based? | Digital? | Volume | Error Rate | Score
     | (1-5)       | (1-5)       | (1-5)    | (1-5)  | (1-5)      | (sum)
-----|-------------|-------------|----------|--------|------------|------
1    | [score]     | [score]     | [score]  | [score]| [score]    | [/25]
2    | [score]     | [score]     | [score]  | [score]| [score]    | [/25]

SCORING GUIDE:
  5 = Highly automatable (always the same, clear rules, fully digital)
  3 = Partially automatable (some variation, some judgment needed)
  1 = Not automatable (creative, subjective, requires human judgment)

RECOMMENDATIONS:
  Score 20-25: Automate fully (RPA, workflow automation)
  Score 15-19: Automate with human review checkpoints
  Score 10-14: Augment with tools (templates, checklists)
  Score 5-9:   Keep manual (human judgment essential)

TOP AUTOMATION CANDIDATES:
  1. Step [N]: Score [X]/25 — Tool: [Recommended tool]
  2. Step [N]: Score [X]/25 — Tool: [Recommended tool]
