We had a client pushing us on our velocity. Our team was doing a quality-first approach which took far more time than the other team's approach to pitch stuff over the wall to QA and wait for bugs to roll in. Our leadership took the deliberate approach of gaming the points system to improve our appearance while keeping the team 100% focussed on deliverying quality work at the same pace we had been all along. We didn't change a thing except inflate our estimates and the client was happy :)
