A periodic review system is an inventory management approach where stock levels are reviewed at regular, predetermined intervals to decide on replenishment quantities. This system helps businesses maintain optimal inventory levels by allowing them to assess stock status and demand trends at fixed times, rather than continuously monitoring inventory levels.

Review Questions
How does a periodic review system facilitate effective inventory management compared to a continuous review system?
A periodic review system simplifies inventory management by allowing businesses to check stock levels and place orders at set intervals rather than constantly monitoring inventory. This can help reduce the labor costs associated with tracking inventory while still ensuring that sufficient stock is available when needed. Additionally, periodic reviews can align with sales cycles, making it easier to manage fluctuations in demand.
Discuss the potential challenges a business might face when using a periodic review system for inventory control.
One challenge of using a periodic review system is the risk of stockouts or overstocking due to infrequent reviews. If demand spikes unexpectedly between review periods, a business may not have enough inventory to meet customer needs. Conversely, if demand drops, excess stock can accumulate, tying up cash flow. Additionally, determining the appropriate review interval requires careful analysis of sales patterns and lead times to strike the right balance.
Evaluate the effectiveness of a periodic review system in a rapidly changing market environment where demand is unpredictable.
In a rapidly changing market with unpredictable demand, a periodic review system may struggle to maintain optimal inventory levels. While it provides simplicity and ease of use, its fixed intervals can lead to significant delays in response to market changes. Businesses may find themselves either understocked during spikes in demand or overstocked during downturns. To improve effectiveness, companies could consider integrating more flexible strategies or combining periodic reviews with elements of continuous monitoring to adapt more quickly to changing conditions.
