Which statement best describes the process for a par stock review when sales are abnormal?

• A. Review sales data
• B. Identify items with high variance
• C. Adjust par levels to reflect usage
• D. All of the above

Answer: (D)

When sales are abnormal, you respond with a data-driven, end-to-end check of your inventory levels. Start by reviewing the sales data to see exactly how actual usage differs from what you expected. This gives you a clear picture of the magnitude and direction of the change. Next, identify items with high variance between forecasted and actual usage, because those are driving the misalignment and most likely to cause stockouts or waste. Finally, adjust the par levels to reflect the new usage patterns, so your stocking aligns with real demand and you maintain the right balance between availability and turnover. All three steps fit together: you can’t reliably set new par levels without understanding the data and pinpointing which items are most affected. This is why choosing all of the above is the best approach.
