The book critically yet entertainingly illuminates the current developments and challenges regarding information management in companies. Many organizations are experiencing significant issues. The handling of information is becoming increasingly complicated, the search for the right information takes longer and longer, and new approaches to comprehensively solving these problems are being hindered by political interests and personal vanity. Buzzwords like "Big Data" and "Digital Transformation" seem to push topics such as information quality and data availability into the background. With the growing complexity of information supply in companies, an information overload is looming. "Act Big" is aimed at professionals responsible within the company and describes a new approach to coordinating company-relevant information: the DARE principle.
