For the logistics service providers, we employed a simple criterion to identify respondents: we considered only those actively engaged in a close relationship with a retailer, which narrowed the field to a few select firms. Three large and significant LSPs eventually agreed to take part. LSP A is an international logistics provider with turnover of nearly £2 billion. The European market is its core geographical focus and the logistics provider is heavily involved in grocery retail logistics. LSP B is a well-known firm not directly involved in grocery physical distribution management. LSP C is a large global firm responsible for a wide range of supply chain services across diverse industry sectors including grocery. As with the supplier sample the logistics firms agreed to participate only with the agreement that no identifying information would be revealed about them or their business context.
