Team role matrix

There has been a bunch of tweets in the #prodmgmt tag displaying a very enlightening matrix on team roles.
Unfortunately the creator did not include the product managers in this matrix. Here is my take on an addition, add your own if you please

Team role matrix

Naturally all of the combinations are stereotyped images. But still I think it is quite interesting to reflect upon how each group is depicted in their view the other roles/actors and how these in reverse view your role in a team.

Since I added the Product Manager row/column I of course had some (although probably too brief) considerations on how I assume other roles view my role, and in reverse. Maybe there is room for adjustment in the matrix…or even improvement on our behalf as Product Managers?
