The effort of what the support staff need to do "support the Increment" is not comparable to the development and qa effort necessary for the increment. The support staff effort is subsumed by the points assigned by qa and dev.

I am questioning the value of their point estimates for work they WILL NOT do, not dismissing them as team members! Developers ensure code maintainability using defined standards. A technical handoff to the support staff is part of our definition of done. The idea that every member is a developer is false in reality. Not everyone can develop software, and no amount of paired programming or knowledge sharing will alter that fact. Support staff participate in other team ceremonies. Refraining from sharing their opinions on story pointing doesn't diminish their contribution to the teams goals.

Thanks for the brutal honesty! I am aware that it is anti pattern. I did tell my director that productivity should be measured against sprint goals! His response was that he is not convinced that it is improper, just because other organizations choose not to do it, it does not mean that it cannot be done by us!!. We actually have organization wide velocity goals - meaning senior management decided how many points on average each team should be delivering and one of my jobs is to keep the team on that trend! Horrifying I know, but how can I, a single individual fight an entire organization?

This was a working agreement formulated by the existing team members

I am a developer and member of the team. I am trying to improve the team and this is one area of struggle!
