Stock Outs and SCMluxe

Stock outs have always been used as a measure of the effectiveness and risk levels of a supply chain. This is mainly due to the retail sector wherein no stocks on the shelf mean a sale  (and revenue) lost forever to a competing product on the shelf. The manufacturing sector also uses stock out metrics to judge the risk levels of a particular inventory plan. For example, critical products like spare parts which B2B customers want on an immediate basis will have a zero stock out policy. This is since spare part non-availability or delay can mean the customer’s production line will have come to a halt. Hence these critical stocks always have very high safety stock levels vis a vis other less critical products. Generic products which can be substituted will follow a more aggressive stocking policy with lower safety stocks. What about the luxury industry? Do they segment products similarly?

As very nicely elaborated by Kapferer and Bastien in thier seminal  book "The Luxury Strategy" the luxury industry believes in limiting supplies to make the brand more desirable. Hence stock outs may not be viewed as entirely a lost sale (as in mass retail) but more as an addition to its brand value. Segmentation is the stock out strategy (or the tolerance towards it) is seen in the luxe industry as well. Limited edition products in absolute luxury categories are the norm. We see limited edition watches, chinaware (where the moulds are ceremoniously broken after production reaches a target volume) all the time to either commemorate a special event or simply to create a uber luxe and highly desirable product.  Similarly prestige brands are typically kept in short supply during introduction to keep interest from flagging and demand being satiated by flooding the market. Apple stores typically have long lines of eager customers camping outside stores on the eve of the launch of the new iPhone or iPad. Online sales are started much later in the sales cycle. Masstige brands on the other hand will start off with  both online and store sales with maximum volumes to ensure the market is fully exploited before competition is able to launch similar products and capture market share.

This segmentation of the stock out policy also has another important angle in SCMluxe – the ability to dispose off over stock. For uber luxe products (Refer post Disposing Overstocks) there is no channel for profitable disposal other than destruction of the product. Hence working on a tolerant zero stock policy by restricting supply also helps cut such losses from overstocking. Prestige and Masstige products on the other hand have channels for disposing excess stock in a more profitable manner and hence can afford to have less tolerant zero stock policies with more safety stocks built into the inventory plan
