Core Workflows

Workflow 1: Context Analysis & Scoping

Purpose: Understand the organization's context, department, scenario, and specific needs.

Step 1: Gather Context Information

Ask targeted questions to understand:

Organizational Context:

• 業種・業界（Industry/sector）
• 組織規模（従業員数、IT部門規模）
• ビジネス目標・戦略
• 現在のIT成熟度（感覚的でも可）

Department/Team Context:

• 対象部門（IT運用、開発、サービスデスク、PMO、セキュリティ等）
• チーム構成とロール
• 現在の課題・ペインポイント
• 期待する成果

Scenario/Situation:

• 具体的なシナリオ（例: インシデント多発、変更失敗率高い、クラウド移行、DevOps導入等）
• タイムライン・緊急度
• ステークホルダー

Step 2: Identify Relevant ITIL 4 Practices

Based on context, identify which of the 34 practices are most relevant:

Examples:

• インシデント多発 → Incident Management, Problem Management, Monitoring & Event Management
• 変更失敗率高い → Change Enablement, Release Management, Deployment Management
• クラウド移行 → Infrastructure & Platform Management, Service Design, Change Enablement
• DevOps導入 → Software Development & Management, Deployment Management, Continual Improvement

Step 3: Define Consulting Objectives

Clearly state:

• What we will assess (current state)
• What we will deliver (recommendations, roadmap, processes)
• Success criteria

---

Workflow 2: Current State Assessment

Purpose: Evaluate current maturity level and identify gaps.

Step 1: Maturity Assessment Framework

Use ITIL 4 maturity model (5 levels) for relevant practices:

Level	Description	Characteristics
Level 1: Initial	Ad-hoc, reactive	No documented processes, firefighting mode
Level 2: Repeatable	Some process definition	Basic documentation, inconsistent execution
Level 3: Defined	Standardized processes	Documented, trained, mostly followed
Level 4: Managed	Quantitatively managed	Metrics-driven, continuous monitoring
Level 5: Optimizing	Continuous improvement	Data-driven optimization, innovation

Step 2: Assess Each Relevant Practice

For each identified practice, evaluate:

Purpose Achievement:

• 目的（Purpose）が達成されているか
• ビジネス価値への貢献度

Key Activities:

• 主要活動が実施されているか
• プロセスの文書化・標準化レベル

Roles & Responsibilities:

• 役割が明確に定義されているか
• RACI マトリクスの有無

Tools & Automation:

• ツールの活用状況
• 自動化レベル

Metrics & KPIs:

• 成果指標の測定有無
• データに基づく改善サイクル

Step 3: Identify Gaps & Pain Points

Gap Analysis Template:

Practice: [プラクティス名]
Current Maturity: Level X
Target Maturity: Level Y

Gaps:
1. [Gap 1: 例: インシデント記録が不完全]
   - Impact: [影響度]
   - Root Cause: [根本原因]

2. [Gap 2]
   ...

Pain Points:
- [ペインポイント1: 例: MTTR が長い]
- [ペインポイント2]

Step 4: Prioritize Issues

Use Impact vs. Effort matrix:

       High Impact
       │
   Q2  │  Q1     ← Focus here first
       │
  ─────┼─────
       │
   Q3  │  Q4
       │
     Low Effort

---

Workflow 3: Recommendation Development

Purpose: Create tailored, actionable recommendations based on ITIL 4 best practices.

Ensure all recommendations align with 7 Guiding Principles:

1. 価値に着目する (Focus on Value)

   • この提案はビジネス価値を生むか？
   • ステークホルダーにとっての価値は何か？

2. 現状から始める (Start Where You Are)

   • 既存の強みを活かせるか？
   • ゼロから作り直す必要があるか？

3. フィードバックをもとに反復して進化する (Progress Iteratively with Feedback)

   • 小さく始めて検証できるか？
   • フィードバックループはあるか？

4. 協働し、可視性を高める (Collaborate and Promote Visibility)

   • 関係者を巻き込んでいるか？
   • 進捗が可視化されているか？

5. 包括的に考え、取り組む (Think and Work Holistically)

   • 4つの次元（組織・人材、情報・技術、パートナー、プロセス）を考慮しているか？
   • 他のプラクティスへの影響は？

6. シンプルにし、実践的にする (Keep It Simple and Practical)

   • 不要な複雑さを排除しているか？
   • 現場で実行可能か？

7. 最適化し、自動化する (Optimize and Automate)

   • プロセス最適化後に自動化しているか？
   • ROI は見込めるか？

Step 2: Design Practice Improvements

For each practice, provide:

1. Quick Wins（即効性のある改善）

• 実施期間: 1-3ヶ月
• 低コスト、高インパクト
• 例: テンプレート導入、簡易ダッシュボード作成

2. Medium-term Improvements（中期改善）

• 実施期間: 3-6ヶ月
• プロセス標準化、ツール導入
• 例: ITSM ツール導入、トレーニング実施

3. Strategic Initiatives（戦略的施策）

• 実施期間: 6-12ヶ月
• 組織文化変革、大規模自動化
• 例: DevOps 文化醸成、AIOps プラットフォーム構築

Step 3: Provide Specific Guidance

Use knowledge base to provide detailed guidance:

Template:

## [Practice Name] 改善提案

### 現状

Common Pitfalls

1. ❌ プロセスのための

プロセス

• ITIL をゴールではなく手段として認識
• ビジネス価値に繋がらないプロセスは排除

2. ❌ 一度に全て実装しようとする

• 「フィードバックをもとに反復して進化する」原則に従う
• Quick Wins から始め、成功体験を積む

3. ❌ ツール先行

• プロセス最適化なしにツールを導入しない
• People > Process > Technology の順序

4. ❌ 現場を無視したトップダウン

• 「協働し、可視性を高める」原則を実践
• 現場の声を聞き、共創する

5. ❌ 成果測定の欠如

• 「現状から始める」には現状把握が必須
• ベースライン測定なしに改善は評価できない

6. ❌ ITIL v3 のマインドセット

• ITIL 4 は v3 の「プロセス」ではなく「プラクティス」
• 価値共創、柔軟性、統合が重視される
