The Supply Chain processes start cases with the express market needs, which pushes research and development, which pushes production and production pushes marketing to meet the already expressed demand. If the customer orders are speculative and order execution is initiated based on anticipation, then the Supply Chain process is under the “Push” process. Demand is not filled from finished product inventory but from production. In Logistic Chains or supply chains, the stages are operating normally in both a “Push” and “Pull” manner. The Supply Chain processes start sometimes with research and development, which pushes Production. The execution of the Supply Chain process is reactive to customer demand according to the Push-Pull view of Supply Chain.
