There is nothing to prevent anyone from creating their own model by using different metaphors.
However, different metaphors will support the creation of a different culture.
It would be possible to create a set of metaphors which underpinned the Hitler's behaviour in the Third Reich. I won't have go here but such a set of metaphors would explain and underpin not only Hitler's behaviour but that of others within his regime.
So what metaphors might other leader's or organizational cultures use?
Microsoft? Churchill? Apple? George Bush? News Corp? Al Queda? British Army? Enron? Hell's Angels? Walt Disney?
None of the above would operate to a common set of of metaphors, although there may be overlap between some.
The point to be reinforced here is that the metaphors used in the Seven Sides of Educational Leadership are linked to the creation of a particular culture - not an accidental or arbitrary selection.
