Explanation:

Strategic control is the process used by organizations to control the formation and execution of strategic plans; it is a specialised form of management control, and differs from other forms of management control (in particular from operational control) in respects of its need to handle uncertainty and ambiguity at various points in the control process.

Strategic control is also focused on the achievement of future goals, rather than the evaluation of past performance. 

The purpose of control at the strategic level is not to answer the question:' 'Have we made the right strategic choices at some time in the past?" but rather "How well are we doing now and how well will we be doing in the immediate future for which reliable information is available?" The point is not to bring to light past errors but to identify needed corrections to steer the corporation in the desired direction. And this determination must be made with respect to currently desirable long-range goals and not against the goals or plans that were established at some time in the past.
