Bullwhip effect: small variations in customer demand become amplified as they move upstream through the supply chain. The key observation is that the oscillating demand is seen more strongly at upstream stages (wholesalers, manufacturers, suppliers) than at the retail/customer end, and those amplified oscillations cause upstream shortages first and then oversupply as firms overreact.

Relevant knowledge points and concepts:
- Demand variability amplification: downstream (retail/customer) demand fluctuations get magnified by ordering, forecasting and batching behavior as they propagate upstream.
- Causes: order batching, lead time, price promotions, misinterpretation of demand, and forecast updates.
- Consequences: large swings in orders to suppliers, resulting in periods of stockouts (shortages) followed by periods of excess inventory (oversupply) at upstream nodes.

Step-by-step reasoning:
1. A small increase or decrease in customer demand at retail is observed by the retailer.
2. The retailer adjusts orders to its supplier; because of safety stock policies, minimum order quantities, or fear of stockouts, the retailer’s order changes are often larger than the original demand change.
3. The wholesaler sees these larger swings and, using forecasting and safety stock rules, places even larger or more erratic orders with the manufacturer. This amplification continues further upstream.
4. As orders grow unexpectedly large, upstream firms may temporarily run out of product (shortages). Once they replenish and see lower demand later, they have excess inventory (oversupply).
5. Thus the oscillation and the shortage→oversupply cycle are observed upstream.

Why the correct answer is “upstream, upstream”:
- The bullwhip effect describes amplified demand oscillations that occur as you move upstream, and the shortages and subsequent oversupply are experienced upstream relative to the customer-facing end.

Why “downstream” choices are incorrect:
- “Downstream” refers to retailers and customers; the original customer variability originates downstream, but the hallmark of the bullwhip effect is amplification and its consequences occurring upstream, not downstream.

Conclusion: The correct selections are upstream and upstream, matching the provided answer.
