Final answer:
Henry Mintzberg found that managers have a dynamic and unstructured work style, often dealing with work overload, role ambiguity, and complex work relationships. Managers must be effective in interpersonal, informational, and decisional roles, and their work style can greatly influence organizational outcomes.
Step-by-step explanation:
The observations that Henry Mintzberg made about managerial work reflect a hands-on, detail-oriented approach where managers are constantly juggling a variety of tasks and responsibilities. In contrast to the Theory X style of managing, which could be considered authoritarian or outdated in some modern work environments, Mintzberg found that managers often work in a dynamic and unstructured manner. They face work overload, deal with conflict, and sometimes have ambiguity in their roles. Managers must also navigate through complex work relationships and ensure they communicate effectively with their teams.
Mintzberg's managerial roles are categorized into three main groups: interpersonal roles which involve interactions with team members, informational roles which involve processing and disseminating information, and decisional roles which require making choices that affect the organization. Each manager's work style can vary greatly—some may be more collaborative, others independent; some may be deadline-driven, while others are big-picture oriented. The efficiency and efficacy of a manager's style can significantly impact the work environment and outputs.
