In summary, CPFR focuses on the process of forecasting supply and demand by bringing various plans and projections from both the supplier and the customer into synchronisation. CPFR requires extensive support in the form of Internet- based products, which can result in major changes to the key business processes. An academic survey of the success of CPFR (Oliveira and Barratt, 2001) found a significant correlation between companies with high information systems capabilities and the success of CPFR projects. The firms with high levels of CPFR implementation use information systems capable of providing timely, accurate, user-friendly and inter-functional information in real time. Skjoett-Larsen et al. (2003) propose that CPFR should be seen as a general approach to integrating supply chain processes, and not as a rigid, step-by-step model as proposed by VICS.
