Warehouse Performance Management in Tesco BACKGROUND: Tesco being the 4th largest online retailer as per revenue and 2nd largest online grocery retailer as per profit is constantly increasing its online grocery business which is being done from its Superstore chain. Tesco introduced a DOTCOM dedicated store more commonly known as DCOS (Dotcom only store) in Aylesford in 2009, which was a huge success and a boost to its online grocery business. As it was highly disturbing for the local superstores carrying out Dotcom business within them in line with the other regular store operations, it was becoming a quite a need to open a dedicated store Dotcom store in London, which TESCO did made possible by opening another DCOS in Greenford London. Tesco needed to reduce the impact of the Dotcom operation in certain stores at the same time addressing space constraints for the Van numbers in particular geographic areas, with a store-based order fulfillment model. This led Tesco to re-evaluate the potential for a dedicated facility.
