Roles of Supply Base Supply Base- suppliers that a firm uses to acquire its materials, services, supplies, and equipment. Firms emphasize long-term strategic supplier alliances consolidating volume into one or fewer suppliers, resulting in a smaller supply base. Preferred suppliers provide: Early supplier involvement- Information on the latest trends in materials, processes, or designs Information on the supply market Capacity for meeting unexpected demand Cost efficiency due to economies of scale Principles of Supply Chain Management: A Balanced Approach by Wisner, Leong, and Tan. © Thomson Business and Professional Publishing

Single-sourcing- a risky proposition. Although trends favor fewer sources, avoid single source. Reasons Favoring More than One Supplier Need capacity Spread risk of supply interruption Create competition Information Dealing with special kinds of business Reasons Favoring a Single Supplier To establish a good relationship Less quality variability Lower cost Transportation economies Proprietary product or process Volume too small to split Principles of Supply Chain Management: A Balanced Approach by Wisner, Leong, and Tan. © Thomson Business and Professional Publishing
