2.  How to take the nature of change into consideration?

In accordance with the size of the gap between the current and desired situation (triangle = important change, circle = continuous improvement), we face either a more or less radical process of change. In the model, ‘change’ is symbolised by rotating the figures.

The degree of effort required to achieve this improvement depends on the shape of the figures (triangle, hexagon, circle), and the extent to which the internal and/or external environment (the slope in the model) is hostile towards the change.
