Study Notes

Predictable Variability in Supply Chains

Predictable variability in demand can be forecasted, but it can negatively affect supply chain costs and responsiveness.
Two main approaches to managing predictable variability:
- Manage supply: Adjust capacity, inventory, subcontracting, and backlogs.
- Manage demand: Employ short-term price discounts and promotions.

Managing Supply

Capacity:
- Flexible workforce scheduling (time flexibility, seasonal hiring).
- Dual facilities (specialized and general-purpose).
- Subcontracting.
- Design flexibility into product production processes.
Inventory:
- Use common components across multiple products.
- Build inventory for items with high demand or predictable demand.

Inventory/Capacity Trade-Off

Maintaining consistent capacity levels leads to higher inventory levels to meet seasonal demand variations.
Low inventory levels require high capacity adjustments to handle peak demand periods.

Managing Demand

Promotions can drive demand growth via:
- Market expansion.
- Competitive advantage.
- Forward buying (customers stock up).
Timing promotion factors:
- Promotion's impact on demand.
- Inventory holding costs.
- Capacity adjustment costs.
- Product margins.
Promotion timing table (Table 9-1):
- High forward buying: promote during low demand.
- Strong market share gain: promote during peak demand.
- Large overall market increase: promote during peak demand.
- High margin: promote during peak demand.
- Low margin: promote during low demand.
- High manufacturer/retailer holding costs: promote during low demand.
- High capacity change costs: promote during low demand.
Promotion effectiveness: Analyze promotion impact on demand, and develop optimal aggregate plan.
When to promote: better to promote during peak or off-peak?

Supply Chain Performance (Table 9-3)

Promotion during peak demand can lead to increased inventory if the demand boost is affected mostly by inventory stocking rather than genuine customer demand.
Profitability can decrease if a promotion only marginally increases customer consumption but causes a significant forward buy.
Profitability increases as promotion increases consumer usage, with the proportion of forward buy decreasing.
Lower product margins make promoting during peak demand less desirable.

Conclusions about Promotion

Average inventory increases with promotions during peak periods and decreases during off-peak periods.
Promoting during peak demand can decrease profit if large forward buying occurs.
More profitable to promote during peak if the demand increase is primarily from customer usage (not forward buys).
Lower margins make peak demand promotions less profitable.
Optimizing profitability requires a coordinated approach involving pricing, production, and inventory management.
Achieving the best outcome requires the alignment and coordinated effort of the entire supply chain.
Strong organizational support and early warning alerts in the sales and operations planning (S&OP) process are crucial.
