Operational & Supply Chain Case Studies: Benihana, Toyota, EV

Benihana of Tokyo Case Analysis

Key Concept:
Benihana’s success stems from a unique operational model combining entertainment, efficient use of space, a simplified menu, and controlled labor costs.

Core Strategies:

  • Hibachi Cooking Style: Chefs cook in front of customers, offering entertainment and reducing back-of-house kitchen space (only 22% of space is non-dining).
  • Limited Menu: Focusing on steak, chicken, and shrimp minimizes food waste and simplifies operations.
  • Labor Efficiency: Requires only highly trained Japanese chefs and limited back-of-house staff, keeping labor costs to approximately 10% of sales.
  • Site Selection: Focuses on high-traffic areas in urban centers to drive consistent lunch and dinner traffic.
  • Beverage Sales: Increased bar/lounge space drives higher margins (up to 33% beverage sales at some locations).
  • Authenticity: All décor and materials are imported from Japan, enhancing the customer experience.

Challenges:

  • Franchising Issues: Loss of control, inexperienced operators, and cultural clashes led to discontinuing the franchise model.
  • Expansion Limits: Growth is constrained by the need for specialized Japanese carpenters and chefs.

Future Plans:

Exploring suburban locations, new quick-service Japanese concepts, and diversification into retail food products.

Toyota Global Chip Shortage Analysis

Key Concept:
Toyota’s renowned Toyota Production System (TPS), built on Just-in-Time (JIT) and Jidoka, faced severe stress during the COVID-19 pandemic and the global semiconductor shortage.

Pre-COVID Preparation:

After the 2011 Fukushima earthquake, Toyota improved supply chain resilience by:

  • Increasing buffer inventory for critical parts (including chips).
  • Mapping all tiers of suppliers for better visibility.
  • Diversifying suppliers geographically.

COVID-19 and Chip Shortage Impact:

  • Initial plant shutdowns occurred due to demand drops.
  • Recovery was disrupted by chip shortages driven by:
    • Increased demand for electronics during remote work.
    • Natural disasters (Texas storm, Japan plant fire) disrupting chip production.
  • Toyota’s buffer inventory provided an initial advantage but was eventually depleted.

Competitor Responses:

  • Tesla: Re-engineered products to reduce chip dependence and rewrote firmware for alternative chips.
  • GM: Partnered with suppliers to develop new microcontroller families.
  • Build-Shy Strategy: Some automakers partially built cars and parked them until chips became available.

Key Lessons:

  • Lean systems work well for predictable disruptions but struggle with prolonged, global crises.
  • Future supply chain strategy may need to balance JIT with “Just-in-Case” buffer inventory.
  • Visibility into lower-tier suppliers is critical.

EV Battery Supply Chain Analysis

Key Concept:
EV demand is surging, but battery supply chain constraints threaten automaker production targets. Fairlane Motor Corporation needs to secure its battery supply for future EV production.

Core Supply Chain Issues:

  • Raw Materials: Lithium, cobalt, and other minerals face extraction challenges, including environmental impact and geopolitical risk.
  • Refining Bottlenecks: Most refining occurs in China, creating geopolitical and supply risks.
  • Manufacturing Delays: Battery factories can be built in 2-3 years, but mines take 7-10 years to develop, creating a potential long-term supply gap.
  • US Policy Impact: The Inflation Reduction Act provides subsidies for US-based battery production, pushing Fairlane to reconsider its Canadian plant location.

Environmental and Ethical Concerns:

  • Lithium extraction consumes vast quantities of water and causes pollution.
  • DR Congo Risks: Child labor and artisanal mining raise significant ESG (Environmental, Social, and Governance) concerns.
  • Mexico: The nationalized lithium industry adds political risk.

Potential Strategies for Fairlane:

  • Secure supply through joint ventures with refiners or miners.
  • Consider direct investments in mining or refining operations.
  • Explore battery recycling as a secondary supply source.
  • Balance ethical sourcing requirements with cost and supply security needs.
