Hi Harry,
I have read an article of David Garvin in HBR. The article was including Xerox Problem Solving approach. It was described by a matrix in the article. Actually as you said it is not much different from the others, but the idea of analysing using a matrix and guiding the team with that kind of a sheet was a different idea. I just wanted to see an example of how that matrix was filled by the team.
Thanks for the reply,
