Informational roles. Managers are required to gather, collate, analyze, store, and disseminate many kinds of information. In doing so, they become information resource centers, often storing huge amounts of information in their own heads, moving quickly from the role of gatherer to the role of disseminator in minutes. Although many business organizations install large, expensive management information systems to perform many of those functions, nothing can match the speed and intuitive power of a well-trained manager’s brain for information processing. Not surprisingly, most managers prefer it that way.
