               communication to written forms because oral media provide greater flexibil-
               ity, require less effort, and bring a faster response. Fifth, managers give high
               priority to maintaining a diverse and complex web of contacts that act as an
               informal information system and helps them execute their personal agendas
               and short- and long-term goals.
                  Analyzing managers’ day-to-day behavior, Henry Mintzberg found that it
               could be classified into 10 managerial roles. Managerial roles are expectations
               of the activities that managers should perform in an organization. Mintzberg
               found that these managerial roles fell into three categories: interpersonal,
                 informational, and decisional.

               Interpersonal Roles.  Managers act as figureheads for the organization when
               they represent their companies to the outside world and perform symbolic duties,
               such as giving out employee awards, in their interpersonal role. Managers act
               as leaders, attempting to motivate, counsel, and support subordinates. Managers
               also act as liaisons between various organizational levels; within each of these
               levels, they serve as liaisons among the members of the management team.
               Managers provide time and favors, which they expect to be returned.

               Informational Roles.  In their informational role, managers act as the nerve
               centers of their organizations, receiving the most concrete, up-to-date informa-
               tion and redistributing it to those who need to be aware of it. Managers are there-
               fore information disseminators and spokespersons for their organizations.

               Decisional Roles.  Managers make decisions. In their decisional role, they
               act as entrepreneurs by initiating new kinds of activities; they handle
                 disturbances arising in the organization; they allocate resources to staff
                 members who need them; and they negotiate conflicts and mediate between
               conflicting groups.
                  Table 12.2, based on Mintzberg’s role classifications, is one look at where
                 systems can and cannot help managers. The table shows that information sys-
               tems are now capable of supporting most, but not all, areas of managerial life.
