The OTB Merchandise Plan is generated for each month’s sales in each classification. The merchandise plan is based on a number of key variables such as store events, monthly stock to sales levels, freshness of inventory (freshness factor) and many other local influences. The OTB projections are made looking 12 months into the future, and adjusted monthly.
Planning is always done at the classification level for many reasons but one big one is that each classification requires a different amount of inventory to support the level of sales in that store (stock to sales ratio). And this level varies on monthly and seasonal basis.
