The most productive QA/dev team experience I had back in the day was in a shop that was playing with eXtreme Programming and we did little 2-3 person strike mission per-issue groups with 2 to 3 devs and 1 QA person. Work on strictly defined small feature and continuously QA through the process, and then iteration end the QA person worked more intensely. The point being that the QA staff was treated like another development engineer even if they weren't writing code, so no "toss this over the fence to QA" and "oh god this is horrible, the devs are shit" mentality. Outcome of the feature was not just completed code, but (hopefully) test plans and sign-off from QA.

The QA people hated it though.
