Collaboration among businesses is currently considered to be driver for growth, cost reduction and innovation in many industries. Collaboration together with technology and visibility is the way how to improve complex multinational supply chains. This publication describes new concepts of collaborative planning in supply chains. The theoretical part depicts developments of supply chain planning from 60s until recent time and shows possible solutions of common supply chain planning problems in form of modern collaborative practices (e.g. Quick Response, Continuous Replenishment, Vendor-managed Inventory, Efficient Consumer Response). In further parts, the work mainly focuses on CPFR (Collaborative Planning Forecasting and Replenisment) concept. There is a separate chapter devoted to benchmarks and pilots of CPFR. In addition to that, practical research of one particular example of CPFR implementation was conducted in cooperation with companies T-Mobile (Deutsche Telekom AG) and Nokia. Results of this research can be found in the last chapter.
