This looks to me like the beginnings of something that could be quite
useful to a LO, or even someone in any organization trying to tackle a
particular problem: a taxonomy of organizational problem-solving tools.
Gavin addresses two dimensions here: time frame and the particular context
of the situation. I'll try to lay out the above to show it more clearly:
Time Frame Situation Model
---------- --------- -----
3 month Shop floor 5 Y's
1 year ??? Kepner-Tregoe
2 year Shop floor TOC
2-5 year ??? SSM, ST
??? accountability, SST
??? recursiveness, VSM
??? SY-SU matching, EKS
Gavin, I apologize if I've distorted your intent.
Would anyone with experience in these or other tools like to add to this,
or perhaps disagree and offer a different taxonomy? (It would also be
useful to add references to the model names.) I can imagine this turning
into something that would be worth maintaining on the LO web site.
