The Peak-Season Review: The December Template That Makes Next Year Cheaper

The Season Pays in Data

The peak season - the Christmas and holiday window that closes the year - pays twice: once in revenue and once in data. The buyers who collect the data during the season can review it in December and make next year cheaper; the buyers who do not collect it review a fog and repeat the same mistakes (see our first-order guide for the same principle on a single order). This guide covers the data to collect during the season, the December review structure and the decisions the review feeds.

The Data to Collect During the Season

The review is only as good as the data collected while the season runs. The sell-through data: which items sold through at the planned rate, which under-sold and which sold out early - tracked by SKU with the inventory records (see our inventory guide for the metrics). The reorder data: which items got reordered, at what response speed, and which reorders were too late to matter (see our Q4 guide for the window). The logistics data: the actual freight rates against the budget, the actual lead times against the plan, the breakage during the peak handling (see our packaging and claims guides). And the market data: what the customers asked for that was not in the program. The rule: the data is collected during the season, not after - the December review reads records, not memories.

The December Review Structure

The review runs in four sections. The sell-through section: the win/loss by SKU - the heroes that carried the season, the slow-movers that consumed the budget, the sell-outs that were reorder misses - with the numbers against the plan. The sourcing section: the supplier performance during the peak - the on-time rates, the quality results, the response times under pressure (see our scorecard guide for the measures) - because the peak is where supplier scores are earned. The logistics section: the freight overrun against the budget, the lead-time surprises, the breakage claims (see our peak-logistics guide for the baseline). And the next-year section: the three or four decisions the review feeds - what to reorder deeper, what to drop, what to add, and what to change in the buying calendar (see our annual-plan guide for where the decisions land).

The Decisions the Review Feeds

The review is not a report - it is the input to next year's plan. The sell-through data sets next season's quantity math (see our inventory guide), the reorder misses set the buffer policy, the logistics overruns set the freight budget and the seasonality assumptions (see our budget-case guide), and the market requests feed the next collection (see our spring-plan guide). The template closes with the action list: each finding converts into a decision with an owner and a date. The buyers who run the December review as a data exercise - collect during, review in December, decide for next year - are the buyers whose next peak season is cheaper, faster and shorter on surprises.
