  Supply chain management encompasses various processes including various
conventional logistics activities, and various other processes These processes
are supported -- to a certain limit -- by coordination and integration
mechanisms which are long-term strategies that give competitive advantage
through overall supply chain efficiency. Information Technology, by the way of
collecting, sharing and gathering data, exchanging information, optimising
process through package software, is becoming one of the key developments and
success of these collaboration strategies. This paper proposes a study to
identify the methods used for collaborative works in the supply chain and
focuses on some of its areas, as between a company and its suppliers (i.e.,
inventory sharing) and its customers (i.e., customer demand, forecasting), and
also the integration of product information in the value chain.
