C) Channel assemblyChannel assembly is an opportunity for effective management in the supply chain. There are multiple opportunities for effectively managing the supply chain including channel assembly. Channel assembly is the technique where a manufacturer sends individual components (rather than assembled units) to a distributor. The distributor is then responsible for final assembly.Multistage control of replenishment is not an effective management technique. Instead, an effective management technique would be single-stage control of replenishment where the responsibility for monitoring and managing inventory is assigned to one member of the supply chain. This removes the distortions and multiple forecasts that create the bullwhip effect.
