To cope with the increase in the number of calls for tenders and suppliers, the increasing complexity of references and the imperative to always reduce the time to market in order to meet the expectations of consumers, the Les Mousquetaires Group has chosen to equip itself with an integrated system for managing its supply and distribution chain. Thanks to purchasing solutions SAP Ariba, different stakeholders can now collaborate through a single interface and according to common processes, thus improving the fluidity and efficiency of operations. Intermarché also has a global vision on all flows and a follow-up of all performance indicators, promoting decision-making and a quick and reliable response to its needs and those of its customers. In addition to the involvement of the teams as soon as possible and a simple and pragmatic approach, the driving change would have been crucial to the success of the project.
