A production manager studies performance reports,

Solution

According to Mintzberg’s Managerial Roles, the Disturbance Handler is the role specifically responsible for taking corrective action when an organization faces unexpected setbacks or "disturbances". 

• Performance Monitoring & Detection: While "monitoring" is the act of collecting data, the question emphasizes the manager’s reaction to a decline in productivity, which constitutes a disturbance to the planned workflow.
• Corrective Action: Reallocating resources and revising schedules in response to a crisis (the productivity dip) are core activities of a manager acting as a Disturbance Handler to stabilize the situation

  Entrepreneur: In Mintzberg's framework, the Entrepreneur role focuses on voluntary improvement and innovation (e.g., launching a new project or product) rather than responding to a negative performance gap. This role is more proactive in nature than reactive. Monitor: The Monitor role is limited to seeking and receiving information to understand the organization's current state. As the question above involves taking action to fix a problem, it is beyond the scope of monitoring. Resource allocator: While the manager does reallocate resources, this is a sub-action taken within the broader context of handling the disturbance. The "Resource Allocator" role typically refers to the routine distribution of funds, staff, and time across various projects. Disseminator: This role involves sharing information with subordinates or others within the organization, which is not the primary focus of the described corrective actions
