This work examines the causes and consequences of the "refocusing" phenomenon, where companies have stopped diversifying and begun focusing once more on their core product lines. Coverage includes a discussion of the effects of refocusing on market value, profitability and organizational structure.

Exploring hypotheses about purposive diversification and ensuing economic performance, this study offers insights into the debate about cooperation versus competition among firms.

Between 2002 and 2008, Japan's economy saw constant expansion, a record among the world's advanced economies and Japan's longest period of economic growth since World War II. This remarkable achievement came about because of a transformation of Japanese business practices. This transformation was guided by strategies that enabled Japan's leading corporations, previously diversified to an exceptionally high degree, to become leaner, more nimble, and more competitive at home and in the global economy. In Choose and Focus, the first in-depth account of this strategic inflection point in Japanese business, Ulrike Schaede argues that the emerging practices and attitudes have created a New Japan. Drawing on profiles of several corporations, including Panasonic, Takeda and Astellas, Softbank, kakaku.com, and SBI E*Trade, Schaede explains how the fundamental principles of Japan's economy have been overturned. "Choose and focus" strategies, whereby corporations concentrate on core areas and spin off unrelated businesses, have completely altered the strategic logic of Japan's previous industrial architecture. These surprisingly aggressive moves, Schaede finds, have created new market opportunities for start-up enterprises and foreign investors, as well as a wave of mergers, acquisitions, and hostile takeovers that have shaken Japanese companies out of complacency. Unlike the advances made by Japanese firms in the 1970s and 1980s, the current transformation is taking root in component and materials industries rather than in consumer products. Because of the relative obscurity of the changes and the overshadowing story of China's ascent, the Japanese corporate revolution has gone largely unnoticed among Western observers. Choose and Focus is required reading for anyone doing business in Japan or trying to understand how contemporary Japanese business works and how Japanese corporations have reinvented themselves to face the challenges—and realize the opportunities—of the 21st century.

​The decision to diversify lies at the core of corporate strategy and is one of the most important decisions for top management. Matthias Knecht introduces a new perspective on corporate diversification that extends the academic discussion and reveals substantial new insights with regards to one of the most pressing questions in strategic management: what makes a diversification strategy successful? The author introduces the dynamism of industries as the dominant force in the firm’s environment that influences the organization on all levels. Due to strategic, organizational, and managerial similarities of businesses competing in similar dynamic environments, synergistic benefits and superior economic performance can be realized through the combination of dynamic-related businesses in the corporate portfolio. This study provides a quantitative, multidimensional operationalization of industry dynamism and an in-depth assessment of the dynamism of a wide range of industries. At the core of the study lies the investigation of the performance impact of dynamic-related diversification strategies. The results provide new insights into successful portfolio construction strategies in the face of today’s dynamic environments.

Large, diversified firms face unique challenges as they compete worldwide, and corporate restructuring is one way multinationals strive for competitive advantage. Weighing the pros and cons of a variety of approaches to restructuring, Downscoping offers executives a clear, strategic path through the maze. The authors show that when a multinational conglomerate fails to compete effectively, too much diversification may be the culprit. Whether the result of weak corporate governance or poor corporate strategy, over-diversification can make managers, unfamiliar with some of the markets in which they compete, opt for safety over innovation. This risk-aversion and lack of long-range commitment to innovation lead inevitably to stagnation over the longer term. The answer is not downsizing--closing offices and laying off personnel--but downscoping: a strategic approach to restructuring. The options include incentive and compensation adjustments for executives, leveraged buy-outs and capital structure changes, focusing on core skills, diversifying internationally while focusing on businesses in which a firm has strong competencies, and buying and selling mature businesses where product development is not a great concern. Regardless of the approach, executives must exercise strategic leadership during and after restructuring, including providing strategic direction, exploiting core competencies, developing human capital, and sustaining the corporate culture. Based on systematic research rather than casual observation, Downscoping provides a strong description of restructuring alternatives and their resulting tradeoffs. Its specific guidelines for maintaining competitiveness will be essential reading for managers involved in corporate restructuring.
