A method for determining a sample size associated with inventory management processes comprises selecting a product population associated with a product inventory and grouping the product population into a plurality of strata. Each strata has a plurality of products, wherein each product includes at least one aspect common to each of the other products of the plurality of products. A sample size for each of the plurality of strata associated with a statistical test count process is determined based on a predetermined criteria. The method also includes performing a statistical test count of each strata, based on the determined sample size, and determining an inventory error based on the statistical test count. The inventory error is compared with a predetermined error threshold. If the inventory error exceeds the predetermined error threshold, the predetermined criteria associated with the sample size is adjusted based on historical inventory error data. If the inventory error does not exceed the predetermined error threshold, an inventory record associated with the product inventory is updated.
