A Framework For Evaluating Supply Chain Performance, Terrance L. Pohlen Sep 2003

A Framework For Evaluating Supply Chain Performance, Terrance L. Pohlen

Journal of Transportation Management

Managers require measures spanning multiple enterprises to increase supply chain competitiveness and to increase the value delivered to the end-customer. Despite the need for supply chain metrics, there is little evidence that any firms are successfully measuring and evaluating interfirm performance. Existing measures continue to capture intrafirm performance and focus on traditional measures. The lack of a framework to simultaneously measure and translate interfirm performance into value creation has largely contributed to this situation. This article presents a framework that overcomes these shortcomings by measuring performance across multiple firms and translating supply chain performance into shareholder value.

Balancing The Logistics Cost-Of-Service Equation In An Increasingly Uncertain Business Environment, Kay Dobie, Jerry Wilson

Journal of Transportation Management

The emphasis in the press, trade publications, and even academic publications is increasingly on supply chain operations, collaboration, and software. There is no argument that these are important considerations as companies struggle to compete in highly competitive markets and an economically difficult environment. This emphasis on “lean” or “JIT” operations presupposes the ability of the firm to operate on a minimum level of inventory and deliver a high level of service. Too often, the basic and vital interdependency between transportation and inventory, necessary to support this objective, is forgotten in the emphasis on the total picture as embodied by the …

Exploring The Diversification Discount: A Focus On High-Technology Target Firms, Donald F. Adkins Jr.

Theses and Dissertations

When firms choose to acquire others, those acquisitions can either be considered diversifying or non-diversifying. Whether the firm diversifies or not has been shown to affect the post-acquisition performance of that firm. Past merger and acquisition (M&A) research has identified a "diversification discount" when firms diversify through M&A activity. However managers continue to diversify, posing the question, "Why do firms continue to diversify in the face of research indicating negative post-acquisition performance"? The answer may be found in that much of the past research has treated all acquisitions the same by analyzing a wide cross-section of acquisitions from industries of …
