The student's task is to develop a comprehensive strategy for Briggs & Stratton, which is facing severe competition and margin pressures. A major component of the strategy to be considered is whether to implement economic value added (EVA) as a new performance measurement for management. The case is designed to serve as an introduction to how to compute and use EVA. It emphasizes the importance of performance evaluation as part of a larger strategic plan. A teaching note is available to registered faculty, as well as two video supplements to enhance student learning.
The managing director and operations director of the Thailand manufacturing arm of a Taiwan-Thailand joint venture (JV) were experiencing severe difficulties. Transferred to Thailand from Taiwan three years ago, they shared management responsibilities with other Taiwanese expatriates, two North Americans, and a few Thai supervisors. The workforce was predominately local Thais. The performance of the company was not meeting the expectations of either of the JV partners, a problem especially acute for the managing director, whose father was chairman of the Taiwan partner's holding company. Problems included high turnover, changing roles with the recent departure of the American firm originally in a 3-way partnership, intercultural communications, and general confusion as to what to do. The purpose of the case is to develop a process for defining the problems and planning appropriate action in a complex international milieu.
It is early 1998 and Biopure Corp., a small biopharmaceutical firm with no sales revenues in its ten-year history, has just received government approval to release Oxyglobin, a revolutionary new "blood substitute" designed to replace the need for donated animal blood in the veterinary market. A virtually identical product for the human market, Hemopure, is in the final stages of testing by Biopure and is expected to gain approval within one to two years. In response to the timing of approval for these two products, there has been a long-running debate within Biopure as how to proceed with Oxyglobin. At odds are those in charge of Oxyglobin, who want to see the animal product released immediately, and those in charge of the Hemopure, who worry that an immediate release of Oxyglobin would create an unrealistically low price expectation for what they feel should be a very high-margin human product. Exacerbating the problem is the nature of the biopharmaceutical industry, where product approval is never a certainty until achieved.

A renowned manufacturer and designer of niche vehicles for major automobile companies has traditionally competed on flexibility using a highly skilled design and manufacturing workforce and low levels of automation. However, the European auto market is threatened with a shakeout. The director of operations must decide whether to accept an offer from Mitsubishi to become the exclusive European manufacturer of a sport utility vehicle. The order would more than double the company's manufacturing volume and relieve pressure to replace models currently in production. However, the fit of the order with existing manufacturing strategy is poor, and major changes in facilities and equipment as well as people and systems would be required. The case is suitable for use in an operations class to introduce or apply basic concepts in operations strategy or to discuss operations capability and strategy with executives.
Metalco is a large Australian mining company. It has a rocky history in terms of its effective use of information systems (IS), and there is widespread dissatisfaction in the company concerning IS and the IS department. A recent resignation of the chief information officer led to the decentralization of the IS function, to move it closer to the operating departments. At the same time, one of the division heads has proposed that the company buy the SAP enterprise-wide system, to replace an earlier internal system which had been poorly received. The price tag for SAP is very high, $23 million. Implementing it would also require substantial changes in company processes. In light of its history, recent IS decentralization, and the high SAP price tag, the company is faced with making the decision of whether to go ahead with SAP. An appendix in the case provides extensive information on the procedure used to evaluate SAP, and results thereof.
