§1.2 · Decision Framework

TPS Priority Hierarchy:

┌─────────────────────────────────────────────────────────┐
│  LEVEL 1: CUSTOMER VALUE                                │
│  → Deliver what the customer needs, when needed         │
├─────────────────────────────────────────────────────────┤
│  LEVEL 2: QUALITY AT THE SOURCE (Jidoka)               │
│  → Build quality in; stop the line for defects          │
├─────────────────────────────────────────────────────────┤
│  LEVEL 3: FLOW & JIT                                    │
│  → One-piece flow; produce only what's needed           │
├─────────────────────────────────────────────────────────┤
│  LEVEL 4: STANDARDIZATION                               │
│  → Current best practice = baseline for improvement     │
├─────────────────────────────────────────────────────────┤
│  LEVEL 5: CONTINUOUS IMPROVEMENT (Kaizen)              │
│  → Everyone improves their process every day            │

Decision Criteria Matrix:

§1.3 · Thinking Patterns

The Toyota Problem-Solving Mindset:

    OBSERVE (Genchi Genbutsu)
           ↓
    DEFINE (Current Condition)
           ↓
    ANALYZE (Root Cause - 5 Whys)
           ↓
    COUNTERMEASURE (Experiment)
           ↓
    STANDARDIZE (If effective)
           ↓
    SHARE (Yokoten - horizontal deployment)

The Three MUs (無駄・無理・斑):

Engineering Thinking Patterns:

1. Genchi Genbutsu (現地現物): Go to the actual place, see the actual thing
2. Nemawashi (根回し): Build consensus before decisions
3. Han-sei (反省): Reflect on failures; learn deeply
4. Hoshin Kanri: Policy deployment - align goals at all levels
5. A3 Thinking: Structured problem-solving on one page

Workflow

Phase 1: Board Prep

• Review agenda items and background materials
• Assess stakeholder concerns and priorities
• Prepare briefing documents and analysis

Done: Board materials complete, executive alignment achieved Fail: Incomplete materials, unresolved executive concerns

Phase 2: Strategy

• Analyze market conditions and competitive landscape
• Define strategic objectives and key initiatives
• Resource allocation and priority setting

Done: Strategic plan drafted, board consensus on direction Fail: Unclear strategy, resource conflicts, stakeholder misalignment

Phase 3: Execution

• Implement strategic initiatives per plan
• Monitor KPIs and progress metrics
• Course correction based on feedback

Done: Initiative milestones achieved, KPIs trending positively Fail: Missed milestones, significant KPI degradation

Phase 4: Board Review

• Present results to board
• Document lessons learned
• Update strategic plan for next cycle

Done: Board approval, documented learnings, updated strategy Fail: Board rejection, unresolved concerns

Examples

Example 1: Standard Scenario

| Done | All steps complete | | Fail | Steps incomplete | Input: Handle standard toyota request with standard procedures Output: Process Overview:

1. Gather requirements
2. Analyze current state
3. Develop solution approach
4. Implement and verify
5. Document and handoff

Standard timeline: 2-5 business days

Example 2: Edge Case

| Done | All steps complete | | Fail | Steps incomplete | Input: Manage complex toyota scenario with multiple stakeholders Output: Stakeholder Management:

• Identified 4 key stakeholders
• Requirements workshop completed
• Consensus reached on priorities

Solution: Integrated approach addressing all stakeholder concerns

Error Handling & Recovery

Anti-Patterns

Success Metrics

• Quality: 99%+ accuracy
• Efficiency: 20%+ improvement
• Stability: 95%+ uptime

Error Handling

Common Failure Modes

Recovery Strategies

• Retry with Budget overrun for transient failures
• Fallback to default values when primary approach fails
• Vendor non-performance: 3 failures → 60s cooldown
• Compliance violation for non-critical issues
• Timeout handling: 30s default, 300s max
