Study Notes
The Supply Chain Process
- Supply chain encompasses all activities from production to delivery to consumers.
- Involves a network of suppliers, producers, and distributors.
- Supply chain management (SCM) focuses on efficient management and control of these activities.
- Global supply chains extend across multiple countries for sourcing and supplying goods.
Just in Time (JIT) and Just in Case (JIC)
-
Just in Time (JIT) aims to minimize stock holding by delivering inventory as needed, eliminating the need for buffer stock.
- Advantages: Reduces storage costs, minimizes obsolete stock, and fosters closer supplier relationships.
- Disadvantages: Relies on technology, can incur high transaction costs, and struggles with demand surges.
-
Just in Case (JIC) retains large stock levels to buffer against supply or demand fluctuations.
- Advantages: Economies of scale from bulk buying, ability to meet unexpected demand spikes, and immediate availability of spare parts.
- Disadvantages: Higher storage costs, risk of theft/damage, and tied-up capital.
Stock Control
- Stocks consist of raw materials, work in progress, and finished goods.
- Stock Control is crucial for maintaining balance and minimizing costs.
- Key costs of stock-holding include opportunity cost, storage costs, and potential for wastage or obsolescence.
- Stock Control Charts track max/min stock levels, reorder levels, and lead times.
Capacity Utilization and Productivity Rates
-
Capacity Utilization Rate measures actual output vs. potential output, reflecting efficiency and idleness.
- High rates are crucial for firms with high fixed costs.
-
Defect Rate measures the percentage of substandard products, impacting quality assessment.
-
Productivity Rates evaluate efficiency in resource use, specifically labor and capital.
- Labour productivity examines output per worker.
- Capital productivity gauges output relative to the hours machines are in operation.
Make or Buy Decision
- Firms weigh the financial implications of producing in-house versus outsourcing.
- Cost formulas:
- Cost to Buy (CTB) = Price x Quantity.
- Cost to Make (CTM) = Fixed Costs + (Variable Cost per Unit x Quantity).
- Decision factors extend beyond costs to include quality, production timelines, supplier reliability, and core competencies.
