2. Background of the research • Globalisation • Complex phenomenon • Expansion of multinational corporations • Advanced technology. • Investment banks • Establishment of cross-border information networks • Multinational style around the 1980’s • Globally networked computer systems • Key factors for global IS • Sharing business vision within a top management team • IS function to integrate of business and IS strategy • Cultural mechanisms for global IS • Western rooted investment banks • Eastern rooted investment banks Hideyuki Matsumoto and David Wilson, The School of Computer Science and Information Systems, Birkbeck College, University of London, 12th December 2004, Page 1

3. Research Questions • Main question • What cultural mechanisms impact on strategic global IS management in a Swiss/American investment bank and a Japanese investment bank? • Sub questions • What are differences and similarities of the following four factors between a Swiss/American investment bank and a Japanese investment bank? • Strategic IS Planning • IS Functions and IT Management Style • IS Human Resource Management • IT Project Sponsor and Champion Hideyuki Matsumoto and David Wilson, The School of Computer Science and Information Systems, Birkbeck College, University of London, 12th December 2004, Page 2

4. Selected Research Method • Cross-Cultural IS Research • Choice of research method and data • How to achieve equivalence • How to prevent and detect bias • Lack of cross-cultural IS research • theory testing and building • culture as antecedents • improvement of research method • Grounded Theory • Scientific process with systematic sequence • Open, axial and selective coding • Theoretical sampling • Theory building and theory testing Hideyuki Matsumoto and David Wilson, The School of Computer Science and Information Systems, Birkbeck College, University of London, 12th December 2004, Page 3

5. Limitation of Research Method Representatives of findings Problem: GT cannot be totally objective. Solution: Presentation the research findings to critical groups Reproducibility of findings Problem: Do same data with same procedure derive same result? Solution: Establishment of clear repeatable procedures Rigor of method Problem: Can not be measured and mathematically proved Solution: Comparison with conflicting frameworks Generalisability of findings Problem: How widely an emerged theory can be applied? Solution: Comparison with similar frameworks Hideyuki Matsumoto and David Wilson, The School of Computer Science and Information Systems, Birkbeck College, University of London, 12th December 2004, Page 4

6. Justification of Research Method • Generation of a grounded theory • The research generates a "Grounded Theory" for • cultural mechanism of strategic global IS management. • Application of a grounded theory • The emerged "Grounded Theory" detects • similarities and differences of cultural mechanisms. • Integration of a grounded theory • The research integrates the emerged "Grounded Theory“ • to identify invisible customs in different cultural regions.
