Case studies

The case compares two U.S. Department of Defense (DoD) programs from the 1970s and 1980s: (1) “stealth” combat aircraft, capable of evading detection or engagement by anti-aircraft systems, and (2) precision attack of hardened ground vehicles from “standoff” distances, i.e., far behind the battle lines. Conceived at roughly the same time, motivated by the same strategic challenge, and initially driven by the same DoD organization, stealth combat aircraft progressed from idea to deployment in less than eight years---an astounding pace for a complex military system---while a demonstrated system for standoff precision strike against mobile ground targets was not fully implemented. The case highlights the critical role of the Defense Advanced Research Projects Agency (DARPA), part of the DoD, regarded as one of the most innovative entities in the U.S. federal government.

The case highlights factors that facilitate rapid, successful implementation of radically innovative or disruptive concepts. Students are introduced to the organizational realities facing such projects, including issues of strategic clarity, interdepartmental competition and cooperation, executive leadership, and timing. Comparing the differences in implementation of the two programs in the case reveals issues relevant to any large organization seeking to bring innovative concepts to fruition.

The diamond industry has been subject to significant change. There is increased competition from low-wage countries such as India and China, the concern about blood diamonds, and policy issues affecting the viability of trading diamonds. In this case, we study how Antwerp's dominant position in the diamond trade is being challenged and eroded. The case offers a good opportunity to introduce and discuss comparative advantage and relate it to Heckscher-Ohlin type of trade.

Supply chain network design choices and the challenges in implementing and understanding how alternatives influence firm performance are key management skills that can be applied to the case of a global company, Kulicke and Soffa Industries, Inc. (K&S), and its expansion strategy. Suitable for the MBA, EMBA, GMBA, and executive education programs, the case explores the decision to expand the company's tool bonding capacity in order to manage its growth. The question becomes whether to grow current operations in Yokneam Israel or seek alternative sites. And if it was decided to seek a location outside of Israel, where exactly should the company go?

Global Connect, a major telecommunications service provider, partners with national cable providers to bundle media and telecom services offered through voice over Internet protocol (VoIP). Global Connect provides the VoIP physical infrastructure that enables cable providers to offer VoIP phone service to their end customers. VoIP cable services are growing at a faster rate than anticipated, leaving Global Connect incapable of meeting contractual agreements with the cable partners and preventing them from capturing substantial VoIP market opportunities. Students are asked to improve the configuration of work at this service organization by identifying the types of waste in the current process. Process improvements use lean tools and their impact is quantified using time and capacity analysis.

To view a service business as a process and to understand where to find the constraints regarding customer responsiveness (flow time) and sales (throughput). This requires a rather subtle capacity analysis.

California telecommunications company Wireworld is considering an acquisition of Nusantara Communications, a subsidiary of Indonesian conglomerate Bakrie & Brothers. Nusantara had invested $50 million in developing the advanced rural telephone system, which had the potential to provide much-needed telecommunications services to the mostly rural Indonesian population. If if were exported, the worldwide market for this product in the next five years was projected to be in the billions. Should Wireworld acquire this small company halfway around the world? Was it prepared to enter the Indonesian marketplace and beyond?

Students will examine a variety of data, including financial projections, in order to decide whether acquiring Nusantara will add value to Wireworld.

Marissa Mayer has been asked to think about factors that were impacting Google's ability to innovate and adjust its strategy so that the organization could remain one of the world's foremost leaders in technology. In an industry (and at a company) that was changing and growing exponentially, it would be difficult to pinpoint specific variables and trends. But Mayer knew that one element crucial to Google's ongoing success would be its ability to recruit the best talent available and foster an environment that would encourage that talent to generate the best ideas. As Mayer contemplated how to ensure this, she considered that women currently represented only a small fraction of Google's engineers, suggesting a missed opportunity.

Mary Kay is one of the best-known direct sellers of women's cosmetics in the world. Its channel strategy is to use independent beauty consultants, who are independent distributors, to sell directly to consumers. Its compensation plan is multilevel, providing commissions to distributors on their own sales as well as the sales of the distributors they recruit. At the time of the case, the company is grappling with a well-established change in consumer behavior—the decline of the stay-at-home mom as she returns to the workforce—combined with the opportunities offered by Internet selling. Focuses on the company's efforts to move with consumer demand and behavior, while remaining true to its core goal of “Improving Women's Lives.” Discusses ways Internet technology can be used throughout the company's channel and supply chain structure, not just as a route to market.

After a highly successful third round of funding in 2012, Gaurav Jain, founder of quick service restaurant chain Mast Kalandar, was looking to expand. In addition to opening new stores in other cities, Jain was also hoping to increase the profitability of his existing stores in Bangalore, Hyderabad, Chennai, and Pune. He needed to fully understand the financials of his current operations and identify the key drivers of success at the stores, at both the city and corporate levels. With this understanding, he would be able to evaluate how best to improve the performance of existing outlets and to choose an entry strategy for new cities. Students are asked to develop a financial model for outlets and use it to compare different growth strategies.

After analyzing this case, students will be able to:

• Assess the strategic and operational tradeoffs being made by the CEO of a company in a growing foodservice sector of an emerging market as he establishes and grows his enterprise

• Build a financial model for outlet operations that identifies key drivers of performance and allows for a comparison between different growth strategies

• Strategically prioritize growth opportunities for a company in response to an influx of new capita

Are hedge funds heroes or villains? Management of Blockbuster, Time Warner, Six Flags, Knight-Ridder, and Bally Total Fitness might prefer the “villain” appellation, but Enron, WorldCom, Tyco, and HealthSouth shareholders might view management as the real villains and hedge funds as vehicles to oust incompetent corporate managers before they run companies into the ground or steal them through fraudulent transactions. Could the pressure exerted by activist hedge funds on targeted companies result in increased share prices, management accountability, and better communication with shareholders? Or does it distract management from its primary goal of enhancing long-term shareholder value?

To determine the benefits and disadvantages of activist hedge fund activity from the perspective of corporate management and shareholders; to examine if a hedge fund's suggested corporate restructuring could create greater shareholder value; and to explain the changing roles and perspectives of hedge funds.

This case requires a decision on the possible consolidation of three Midwest business-travel centers. Significant cost savings in service representatives can be achieved by combining the front-end (booking) operations. The sensitivity of cost to service-productivity levels and customer waiting time is also explored. This case and related materials can be used as part of the Workforce Planning Module.
