🏭 JIT Implementation Simulator

Congratulations on your appointment as Operations Manager of ManuTech Industries.

The board has authorised a full transition from traditional Just in Case (JIC) inventory management to Just in Time (JIT). Your mission: plan and execute the transformation over three rounds spanning 12 months.

Every decision you make will update the company's live metrics in real time — watch the numbers change as you commit to each choice.

✅ Why switch to JIT?

Frees up tied-up working capital
Reduces warehouse overhead costs
Cuts stock obsolescence losses
Improves cash flow position
Encourages lean, efficient culture

⚠️ Risks of JIT

Vulnerable to supply chain disruptions
Requires reliable, trusted suppliers
Zero tolerance for quality failures
High dependency on IT systems
Staff resistance to change

Planning the Transition

You've announced the shift to JIT. Now make three foundational decisions. Each choice updates your performance metrics immediately — watch what happens to efficiency, relationships, cost and risk as you decide.

⏱️

Decision time remaining

Decision 1: How will you manage workforce resistance?

📚 Change management · AQA 3.6

📚 Comprehensive Training Programme

Invest £150K in training, workshops and change management. Involve employees throughout the transition.

High buy-inSmoother transition£150K cost

⚡ Top-Down Mandate

Announce changes and expect compliance. Provide basic briefings only. Focus budget on systems rather than people.

Faster rolloutLower costResistance risk

🎯 Pilot Programme

Trial JIT in one volunteer department. Use early success to build momentum and win over sceptics gradually.

Lower riskModerate costSlower rollout

Decision 2: How will you prepare your suppliers?

📚 Supply chain · AQA 3.5

🤝 Strategic Partnership

Reduce supplier base from 45 to 12 key partners. Offer long-term contracts with guaranteed volumes. Share forecasts, collaborate on quality.

Strong relationshipsBetter qualityHigh dependency

💰 Maintain Competition

Keep all 45 suppliers but demand JIT delivery terms. Use competitive pressure to negotiate lower prices.

⚖️ Tiered Supplier Strategy

Create a preferred tier of 20 suppliers with better terms, maintain 25 backup suppliers for security.

Round 2 · Months 4–9

Facing the Challenges

Three months in — and the teething problems have arrived. Navigate these crises while maintaining operations and stakeholder confidence.

⚠️ Supply Disruption: Severe weather in Europe has delayed key component shipments by 5 days. The production line may halt.
💷 Cost Pressures: Suppliers are requesting 8–12% price increases, citing small batch sizes and frequent deliveries.
📉 Quality Issues: Increased delivery frequency has led to three batches of substandard components slipping through.
😟 Workforce Anxiety: Staff are reverting to old practices. Some departments are rebuilding informal buffer stocks.

Decision 4: How do you handle the supply disruption?

📚 Supply chain risk · AQA 3.5

🚨 Emergency Stock Purchase

Source components from alternative suppliers at a 35% premium. Rebuild a small buffer stock for critical items.

Maintains productionHigh costUndermines JIT

🔄 Production Flexibility

Shift production to products using available components. Work with customers to adjust delivery schedules temporarily.

Stays true to JITCustomer goodwill neededDisrupted schedules

🛡️ Dual Sourcing Strategy

Expedite from secondary supplier (20% premium). Implement geographic diversification for critical components going forward.

Future resilienceBalancedModerate cost

Decision 5: How do you respond to supplier price increases?

📚 Supplier relations · Lean production · AQA 3.5

✅ Accept and Adjust

Accept the increases but negotiate 6-month fixed pricing. Work to improve efficiency elsewhere to offset costs.

Maintains relationshipsHigher input costsMargin pressure

💬 Aggressive Negotiation

Counter with 4% maximum. Threaten to switch suppliers. Increase batch sizes slightly to reduce their costs.

Controls costsRelationship strainCompromises JIT

🎯 Value Engineering

Accept 5% short-term but collaborate with suppliers on component redesign to reduce their costs long-term. Share the savings.

True partnershipLong-term savingsShort-term cost

Decision 6: How do you address quality concerns?

📚 TQM · Quality at source · AQA 3.5

🔍 Enhanced Inspection

Rigorous receiving inspection for all deliveries. Hire 3 additional quality inspectors at £120K/year.

Catches defectsSlower receiving£120K cost

🏭 Supplier Quality Programmes

Work with suppliers to improve their own quality control. Conduct audits, share standards, provide support.

⚖️ Performance-Based Contracts

Implement penalty clauses for quality failures. Pay premiums for perfect quality records. Data-driven accountability.

Round 3 · Months 10–12

Harvesting the Benefits

Twelve months in — the initial challenges have been navigated. JIT benefits are becoming tangible. Now decide how to maximise and sustain the gains.

Decision 7: What do you do with freed warehouse space?

📚 Asset management · Capital allocation · AQA 3.5

💰 Sell the Asset

Sell 9,000 m² for £2.7M. Immediate capital gain. Lease back small buffer space if ever needed.

£2.7M cashReduced overheadLess flexibility

🏭 Convert to Production

Invest freed space into new production capacity. Expand output or enter new product lines.

Revenue growthBetter asset useRequires investment

📋 Lease to Third Party

Lease excess space for £180K/year. Steady income while retaining ownership and optionality.

Steady incomeRetain assetModerate return

Decision 8: How do you deploy the freed cash flow?

📚 Stakeholder objectives · Capital allocation · AQA 3.7

💵 Return to Shareholders

Pay a special dividend of £1.2M. Reward shareholders for supporting the transformation.

🤖 Automation Investment

Invest in robotics and AI quality control. Further reduce labour costs and improve consistency.

Decision 9: How do you sustain supplier relationships long-term?

📚 Supply chain excellence · Kaizen · AQA 3.5

🔗 Deep Integration

Implement vendor-managed inventory and data sharing with key suppliers. Create unprecedented supply chain efficiency.

Just in Time (JIT)

A lean production method where materials arrive exactly when needed, eliminating buffer stock and reducing working capital tied up in inventory.

Just in Case (JIC)

Traditional approach holding large safety stocks to protect against supply disruption — costs more but provides security.

Lean Production

A systematic approach to eliminating waste (muda) in all forms — excess stock, waiting time, overproduction, unnecessary motion.

Kaizen

Japanese philosophy of continuous incremental improvement involving all employees. Central to sustaining JIT after implementation.

Kanban

Visual signalling system used in JIT to trigger production or replenishment only when demand requires it — prevents overproduction.

TQM (Total Quality Management)

Quality management philosophy ensuring every employee is responsible for quality — critical in JIT where defects cannot be absorbed by buffer stock.

Working Capital

Current assets minus current liabilities. JIT frees working capital by reducing inventory, improving cash flow and financial flexibility.

Supply Chain

The network of organisations, activities and resources involved in creating and delivering a product from raw materials to the end customer.
