Compare a conventional distribution channel with a vertical marketing system (VMS)

What will be an ideal response?

A conventional distribution channel consists of one or more independent producers, wholesalers, and retailers. Each is a separate business seeking to maximize its own profits, even at the expense of the system as a whole. No channel member has much control over the other members, and no formal means exists for assigning roles and resolving channel conflict. On the other hand, a vertical marketing system is a unified system made up of producers, wholesalers, and retailers. While members of a conventional distribution channel seek to maximize their own profits, members of a vertical marketing system all cooperate because either one member owns the others, one has contracts with the others, or one wields more power than the others.
