TOC Strategy and Tactic Trees
First, understand the precise difference between strategy and tactics (link will open in new window).
Now, watch this short but knowledge-packed video with Alan Barnard on the use of TOC Strategy and Tactic Trees:
The tree is only as valid as our assumptions.
- First we make assumptions about why the change is necessary to achieve the top objective
- Second, we ask why the specific objective or strategy is possible, or why the tactic or the how-to is the best way of doing it.
- And lastly we make an assumption about why we claim that these changes in combination are sufficient to achieve the top objective.
S&T allows you to identify all the changes that are needed, and fill in the details of the assumptions.
The following questions are used to develop a S&T Tree:
- Why is the Change needed? (Necessary Assumption)
- What is the specific measurable objective of the change (Strategy)
- Why do you claim the Strategy is possible and what must be considered when selecting from the alternative ways of achieving the Strategy (Parallel Assumptions linking Strategy with Tactic)
