Successful organizations identify and evaluate alternative ways to reach their ultimate market. Possible approaches vary from direct selling to using just one or many wholesalers and retailers. Strengths and weaknesses of each channel alternative should be determined according to economic, control, and adaptive criteria. Organizations should consider the costs and benefits of various wholesaling and retailing options. They must consider the need to motivate and control channel members and the need to adapt to changes in the future. Once a marketing channel is chosen, an organization usually must adhere to it for an extended period of time.
