While there are many nuanced ways of doing this, they may get very operationally difficult -
Eg, linking PB to say Code commit delivery, or code quality, bug resolution (for QA) etc -> these wil get very tough to execute and track.
Why not extend the same policy as with everyone else and tie it to the Performance ratings.
We followed business metrics achievement, as we see Tech to be a part of business and if business wins, eveyone who contributed to it, Tech included, get disproportionately rewarded.
Easy to execute, everyone happy.
