This new study is the first part of a major initiative focussed upon developing a detailed understanding of not only what approaches retailers are adopting to manage the various types of SCO system they are operating, but also offer insights into how they are being used and their effectiveness. It is a major undertaking based upon a global survey of retailers, detailed insights from SCO supervisors, and extensive case studies from a wide range of retailers. The overall goal is to provide the retail industry with new knowledge, insights and practices that will enable it to meet the twin goals of improving consumer convenience and business profitability.
