Inventory Management: Managing Inventory (Copy)

4.2.1 Managing Inventory

The Purpose Of Inventory Within A Business (Raw Materials, Work In Progress, Finished Products)

• Raw Materials
  • Basic inputs required for production (e.g., steel, cotton, wood, fuel).
  • Purpose: Ensure production can continue without disruption.
  • Example: A bakery holding flour, sugar, and eggs.
• Work In Progress (WIP)
  • Partially completed products still in the production process.
  • Purpose: Smoothens workflow and avoids bottlenecks.
  • Example: Half-assembled cars on a production line.
• Finished Products
  • Goods completed and ready for sale.
  • Purpose: Meet customer demand immediately, avoid delays.
  • Example: Smartphones stored in warehouses before launch.

The Costs And Benefits Of Holding Inventory

• Costs
  • Storage Costs: Warehousing, rent, electricity, and handling.
  • Insurance Costs: Protecting goods against damage, theft, or accidents.
  • Obsolescence Risk: Products becoming outdated or unsellable (e.g., seasonal fashion).
  • Capital Costs: Money tied up in stock cannot be used elsewhere.
  • Spoilage And Wastage: Perishable goods (food, medicine) risk expiry.
• Benefits
  • Smooth Production: Prevents delays from shortages.
  • Meeting Customer Demand: Quick delivery enhances satisfaction.
  • Bulk Discounts: Buying in large quantities reduces cost per unit.
  • Buffer Against Uncertainty: Protects against supply chain delays or sudden demand spikes.
  • Improved Reputation: Reliable stock levels build trust with customers.

Buffer Inventory, Re-Order Level And Lead Time

• Buffer Inventory (Safety Stock)
  • Extra stock held to guard against uncertainties in demand or supply.
  • Example: A supermarket keeping additional milk supply before holidays.
• Re-Order Level
  • The stock level at which new inventory must be ordered.
  • Formula:
    Re-order Level = Lead Time Demand + Buffer Stock
  • Ensures new stock arrives before existing inventory runs out.
• Lead Time
  • The time between placing an order and receiving delivery.
  • Longer lead times require higher buffer stock.
  • Example: Importing electronics may take weeks, requiring careful planning.

Interpretation Of Simple Inventory Control Charts

• Inventory Control Chart: Visual tool showing stock levels over time.
• Key Elements:
  • Maximum Inventory Level: Highest stock a business should hold (avoids high costs).
  • Minimum Inventory Level: Lowest stock before production/sales are threatened.
  • Re-Order Level: Point at which new orders are placed.
  • Lead Time: Gap between placing and receiving orders.
• How It Works:
  • Stock decreases as goods are used/sold.
  • When stock reaches the re-order level, a new order is placed.
  • Buffer stock ensures production continues during lead time.
• Example:
  • A clothing retailer uses charts to ensure stock is replenished before seasonal demand peaks.

The Importance Of Supply Chain Management (SCM)

• Definition: Coordinating the flow of raw materials, components, and finished goods from suppliers to customers.
• Key Roles Of SCM:
  • Selecting reliable suppliers.
  • Ensuring timely delivery of inputs.
  • Managing logistics and transportation.
  • Minimising costs while maintaining quality.
  • Building strong relationships with stakeholders in the supply chain.

• Benefits Of Effective SCM:
  • Reduces delays and disruptions.
  • Enhances customer satisfaction by ensuring availability of products.
  • Improves efficiency, reducing waste and costs.
  • Strengthens competitiveness in global markets.
• Challenges Of SCM:
  • Globalisation increases complexity.
  • External risks (natural disasters, pandemics, political instability).
  • Managing ethical and environmental concerns in supplier networks.
• Examples:
  • Amazon’s advanced supply chain ensures same-day delivery in many cities.
  • Toyota’s Just-In-Time supply system minimises storage costs but requires reliable suppliers.

Strategic Importance Of Inventory And SCM

• Effective inventory management balances too much stock (high costs) with too little stock (lost sales).
• SCM integrates procurement, production, and distribution to achieve corporate objectives.
• Businesses that fail in inventory and supply chain planning face inefficiency, customer dissatisfaction, and reduced profits.
• Example: During COVID-19, poor supply chain management caused shortages of PPE and medical supplies, while firms with strong SCM adapted quickly.
