Question 1

1.1 Describe each of the three levels of management that usually exist in an
organisation.

1. Operational (Lower-Level) Management
This level includes supervisors, team leaders, and frontline managers who
handle day-to-day operations. Their main role is to implement plans and monitor
routine tasks.
2. Middle Management
This level includes departmental heads and division managers. They translate
strategic goals from top management into specific plans and oversee their
implementation at the operational level.
3. Top (Strategic) Management
This level includes executives such as CEOs, CFOs, and board members. They
are responsible for setting the overall direction, strategic goals, and policies of
the organisation.




1.2 What kind of decision support does a database management system (DBMS)
give to the first level YOU mentioned?

 Real-time data access: Enables staff to view live inventory levels, customer
orders, or production status.

transactions (e.g., sales, payroll).
 Monitoring performance: Helps in tracking employee attendance, delivery
schedules, and quality checks.
