The CPFR movement originated in 1995. It was the initiative of five companies: Wal-Mart, Warner-Lambert, Benchmarking Partners, and two software companies, SAP and Manugistics. The goal was to develop a business model to collaboratively forecast and replenish inventory. An initial pilot was tested between Wal-Mart and Warner-Lambert using the Listerine mouthwash product and focusing on stocks kept in the retail outlets. The concept and process was tested initially by exchanging pieces of paper. This generated clear visibility of the process required and the requirements for the IT specification. The two companies later demonstrated in a computer laboratory that the Internet could be used as a channel for this information exchange.
