Spell out these broad strategic intentions of the strategic plan in other types of plans, including business plans.
You might call business planning that converts the corporate strategy into clear actions with resources strategic business planning. While there may be some overlap between strategic planning and business planning, they are not the same thing.
I think it is helpful to separate the term ‘strategic’ from the term ‘business’.
Corporate strategic planning differs from business planning. They have different planning time horizons, different flavors of forecasts, different levels of detail, mostly different intended audiences, and a different balance of words and numbers.
The kind of thinking involved in business planning that is 'strategic', differs from long-range planning.
Long-range planning with the present and sets out steps to meet estimated future needs.
If such business planning is business planning aligned with, and designed to implement corporate strategy there would not be much of a problem.
However, sometimes it is just a matter of trying to make the ordinary business planning sound a bit more important than just a budget!
This usually involves extrapolating from past performance to forecast likely future performance.
This makes sense in a stable or very slowly changing environment.
