Some compare the evolving web to the revolution of the Gutenberg press. How does the web shape the role and understanding of leadership? What are key challenges and opportunities? What mind-sets, skills, and knowledge are necessary? This book analyzes over 300 pioneering web-use examples from the private, public, and nonprofit sector in Germany, Europe, and the United States. A new leadership paradigm seems to be emerging with an inexorable shift away from one-way, hierarchical, organization-centric communication toward two-way, networkcentric, participatory, and collaborative leadership styles. What requirements, trends, opportunities, and key challenges are emerging for leadership? The study aims to enable managers from all sectors to anticipate changes and proactively take advantage of opportunities that are emerging. Target groups for this publication are people in leadership positions in organizations across all sectors - from managers in executive and supervisory boards, operations, and human resources to academics and practitioners, advisers, and policymakers.
