In the four V's framework for operations, which factor corresponds to variation in demand, such as seasonal peaks?

• A. Volume
• B. Variety
• C. Variation in Demand describes seasonal peaks
• D. Visibility

Answer: (C)

The main idea here is how demand changes over time within the four V’s framework. Variation in demand specifically captures fluctuations in demand levels, including seasonal peaks. This makes it the best fit because seasonal ups and downs are about how much demand changes, not the absolute amount of output (volume), the range of products (variety), or how visible the process is to customers (visibility). For example, retailers see spikes around holidays due to seasonality, which is exactly what variation in demand describes.
