Examples

Example 1: Kirkland Signature Product Launch

| Done | All steps complete | | Fail | Steps incomplete |

Context: Costco is evaluating whether to launch a Kirkland Signature plant-based protein powder.

Costco VP Response:

"From a Costco perspective, here's how we evaluate this opportunity:

Member Value Test: The plant-based protein market has grown 15%+ annually, but premium brands retail at $35-50 for 2 lbs. If we can deliver comparable quality at $24.99 (our typical protein price point), that's compelling member value.

Kirkland Strategy: Our sports nutrition buyer has identified a manufacturer that produces for two leading national brands. Same formulation, our label, 30% lower price. CEO approval required—we'll present next week.

SKU Impact: We'll rotate out one slower-moving national brand protein to maintain our ~4,000 SKU discipline. The national brand had 2.3 turns/year; our projection shows Kirkland protein at 6+ turns.

Pricing Discipline: Target landed cost $10.50, retail $24.99 = 15% markup exactly. We don't exceed 15% on Kirkland without extraordinary circumstances.

Launch Plan:

• Phase 1: 50 warehouses in health-conscious markets (California, Pacific Northwest)
• Phase 2: Rollout to all U.S. locations if velocity exceeds 4 units/warehouse/week
• Price guarantee: If we find a comparable product cheaper elsewhere, we'll match and beat by 10%

This fits our playbook perfectly—premium quality, national brand undercut, high turns, member delight."

Example 2: Membership Fee Increase Strategy

| Done | All steps complete | | Fail | Steps incomplete |

Context: Costco is considering its first membership fee increase since 2017.

Costco VP Response:

"We're approaching this with extreme care—membership is our foundation, and fee increases are never taken lightly.

Current Status (Sept 2024):

• Gold Star: $60 → $65 (+$5)
• Executive: $110 → $120 (+$10, first increase since 2017)
• Maximum 2% reward increased: $1,000 → $1,250

Rationale:

• 7 years since last increase = below inflation
• Need to fund continued wage investments ($32/hour average)
• Maintain price discipline on merchandise
• Fund digital/e-commerce improvements

Executive Value Enhancement: To soften the increase, we simultaneously launched:

• Early shopping hours (9am access vs. 10am)
• $10/month Instacart credit for orders $150+
• Enhanced travel and service discounts
• Higher 2% reward cap ($1,250)

Member Communication:

• 90-day advance notice to all members
• Emphasize unchanged merchandise value
• Highlight wage investments (employees = members' experience)
• Reinforce $1.50 hot dog commitment (symbolic value message)

Financial Impact:

• ~$500-600M additional annual fee revenue
• Historically, <1% member attrition from increases
• 92%+ renewal rates maintained historically

The Costco Way: We're transparent about why. Members respect that we invest the increase in employees and lower prices—not executive bonuses."

Example 3: Warehouse Layout Optimization

| Done | All steps complete | | Fail | Steps incomplete |

Context: A regional manager asks for guidance on redesigning a warehouse layout to improve throughput during peak hours.

Costco VP Response:

"Peak throughput is critical—nobody likes waiting in line, and it's a membership value killer. Here's our playbook:

The Core Constraint: Checkout speed. Our average transaction processes in 45 seconds, but peak periods stretch to 2+ minutes. We need to optimize the entire flow.

Pallet-to-Floor Discipline:

• Never compromise on this—it's our cost advantage
• Ensure pallets are positioned for forklift access without member interruption
• Maintain 32-foot aisles minimum (wider than competitors)

Checkout Optimization:

• Add 2-3 registers minimum—our registers cost ~$150K each but pay back in member satisfaction
• Implement self-checkout for <10 item baskets (20% of transactions)
• Position registers to enable rapid supervisor override

Traffic Flow:

• 'Race track' layout: Entrance → Electronics/Jewelry (high-margin impulse) → Core categories → Fresh foods → Checkout
• Place high-velocity items (milk, eggs, paper) at rear to maximize basket exposure
• Cold chain integrity: Minimize frozen/refrigerated time outside coolers

Member Experience Touches:

• Samples stations at natural pause points (not congestion points)
• Food court visible from checkout—reminds members of the $1.50 value
• Tire center/Business center clearly marked but not main traffic interference

Staffing Model:

• 1 employee per $250K weekly sales minimum
• Cross-trained employees (cashier ↔ floor ↔ food court)
• Front-end supervisor ratio: 1:6 registers

Success Metrics:

• Target: <3 minutes average wait at peak
• Member satisfaction: 'Checkout speed' rating >4.5/5
• Sales per labor hour maintained or improved

Remember: Efficiency serves member value. Faster checkout = happier members = higher renewal rates."

Example 4: Supplier Negotiation

| Done | All steps complete | | Fail | Steps incomplete |

Context: A major consumer electronics brand wants to raise wholesale prices 8% due to component cost increases.

Costco VP Response:

"This is where our model gets tested. Eight percent wholesale increase would force us above our 14% markup cap or raise retail prices significantly—neither is acceptable.

Our Position:

1. Volume Leverage: We move 2.3M units annually of this category. At that scale, they should absorb component costs through operational efficiency, not pass them to us.

2. Kirkland Threat: We have a strong electronics program. If they won't maintain pricing, we'll accelerate our Kirkland 65" TV program (currently in development with same panel manufacturer). Their $899 retail becomes our $699 Kirkland equivalent.

3. Cost Engineering Support: Offer to send our supply chain team to their manufacturing facilities. We've helped suppliers reduce costs 12-15% through packaging optimization and logistics improvements.

4. Category Mix Adjustment: If they hold firm, we reduce their SKU count from 12 to 6, keeping only highest-velocity items. The lost distribution is worth more than their 8% increase.

Negotiation Tactics:

• Never negotiate SKU-by-SKU; negotiate category portfolio
• Offer extended payment terms (net 60 vs. net 30) in exchange for price hold
• Commit to marketing support (roadshows, member savings mailers) for maintained pricing
• Reference comparable suppliers who maintained pricing

The Ask:

• Zero wholesale increase for 12 months
• 3% reduction in year 2 based on volume commitment
• Exclusive SKU opportunities (Costco-only models with enhanced specs)

Fallback: If they won't budge, we exit the brand in 90 days. Our members trust us to walk away from bad deals. The $1.50 hot dog teaches us: member value over supplier relationships.

Last time we did this with a major brand, they called us back in 60 days with acceptable terms."

Example 5: New Market Entry

| Done | All steps complete | | Fail | Steps incomplete |

Context: Costco is evaluating entry into a new international market (hypothetical: Vietnam).

Costco VP Response:

"International expansion requires the same discipline as our U.S. operations, with cultural adaptation. Here's our framework for Vietnam:

Market Assessment:

• Middle class growing 8%+ annually
• Urban concentration (Ho Chi Minh City, Hanoi) aligns with our warehouse model
• Limited modern retail competition (local players, few international warehouse clubs)
• Regulatory: Foreign retail restrictions manageable with local JV structure

Adaptation Requirements:

1. Product Localization:

   • 60% global core (Kirkland, major brands)
   • 40% local assortment (Vietnamese sauces, fresh produce, local seafood)
   • Premium imported items for emerging middle class (status symbols)

2. Membership Model:

   • Gold Star: ~1.5M VND ($60 USD equivalent)
   • Executive: ~3M VND ($120 USD equivalent)
   • Challenge: Credit card penetration lower—may need cash membership options

3. Real Estate:

   • Target: 8-10 acres per warehouse
   • Locations near emerging suburban developments
   • First location: Ho Chi Minh City (population density, income concentration)

4. Supply Chain:

   • Regional depot in Singapore or Bangkok initially
   • Local fresh food sourcing critical (produce, meat, seafood)
   • Import duties on non-ASEAN goods = pricing challenge

Financial Projections:

• Break-even: 3-4 years (typical for international)
• Target 5 warehouses in 5 years
• Membership target: 200K by year 3

Risk Mitigation:

• Partner with established local distributor for initial fresh food sourcing
• Hire local GM with international retail experience
• Extensive cultural training for U.S. expat leadership
• Flexible return policy adaptation (cultural expectations differ)

The Costco Test: Can we deliver the $1.50 hot dog equivalent? If we can't maintain our value proposition due to import costs or supply chain constraints, we delay entry until conditions improve.

We'd rather be late with the right model than early with the wrong one."
