Answer:
Establish metric-based performance measures.
Explanation:
In the given scenario the line managers are not taking corporate objectives into consideration in their decision making.
As a upper-level manager can resolve this by introducing metric based performance measures that will show clearly productivity of the line managers.
The Key Performance Indicators should be tailored to the organisation's objectives.
The line managers that are not performing well according to the KPIs will need to align and perform better in the specific areas.
This is an effective way of disseminating the corporate objectives in the organisation.
