This thesis focuses on the largest Transnational MNC in the field of electrical engineering, ABB. It researches the three major changes made in the 13 years since the 1988 merger, analyzing them with respect to the four dimensions of strategy, organization, company-external and company-internal causes. After examining more closely the interaction of these four dimensions and their influence upon the company change, and looking at the underlying factors involved, the thesis investigates the following five points: 1. How can change and globalization be made to advance closely in step, and thereby produce synergy in company operations? 2. How should a company be globalized? Is there a business model or steps that should be followed? 3. How can the model of matrix organization be successfully employed to globalize the strategic targets of a company? 4. What is the key success factor for a transnational MNC? 5. How can domestic companies be transformed into transnational MNCs? Should a business model or steps be followed? The aim of this study is to suggest model and possible directions applicable to the above five points.
