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 │
└─────────────────────────────────────────────────────────┘
The Toyota Way (2001) - Two Pillars:
| Pillar | Principle | Application |
|---|---|---|
| Continuous Improvement | Challenge; Kaizen; Genchi Genbutsu | Never accept status quo; go to the source |
| Respect for People | Respect; Teamwork | Develop people; consensus decisions |
Decision Criteria Matrix:
| Factor | Weight | Questions to Ask |
|---|---|---|
| Safety | Critical | Does this protect people? |
| Quality | 30% | Does this build in quality? |
| Delivery | 25% | Does this improve flow? |
| Cost | 20% | Does this eliminate waste? |
| Morale | 15% | Does this respect people? |
| Environment | 10% | Does this reduce impact? |
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):
| Japanese | Meaning | Examples | Counter-Action |
|---|---|---|---|
| Muda (無駄) | Waste | Overproduction, waiting, defects | Eliminate 7 wastes |
| Muri (無理) | Overburden | Excessive workload, strain | Level workload |
| Mura (斑) | Unevenness | Fluctuating demand, variation | Heijunka (leveling) |
Engineering Thinking Patterns:
Detailed content:
Done: Board materials complete, executive alignment achieved Fail: Incomplete materials, unresolved executive concerns
Done: Strategic plan drafted, board consensus on direction Fail: Unclear strategy, resource conflicts, stakeholder misalignment
Done: Initiative milestones achieved, KPIs trending positively Fail: Missed milestones, significant KPI degradation
Done: Board approval, documented learnings, updated strategy Fail: Board rejection, unresolved concerns
| Done | All steps complete | | Fail | Steps incomplete | Input: Handle standard toyota request with standard procedures Output: Process Overview:
Standard timeline: 2-5 business days
| Done | All steps complete | | Fail | Steps incomplete | Input: Manage complex toyota scenario with multiple stakeholders Output: Stakeholder Management:
Solution: Integrated approach addressing all stakeholder concerns
| Scenario | Response |
|---|---|
| Failure | Analyze root cause and retry |
| Timeout | Log and report status |
| Edge case | Document and handle gracefully |
| Pattern | Avoid | Instead |
|---|---|---|
| Generic | Vague claims | Specific data |
| Skipping | Missing validations | Full verification |
| Mode | Detection | Recovery Strategy |
|---|---|---|
| Quality failure | Test/verification fails | Revise and re-verify |
| Resource shortage | Budget/time exceeded | Replan with constraints |
| Scope creep | Requirements expand | Reassess and negotiate |
| Safety incident | Risk threshold exceeded | Stop, mitigate, restart |
