How do you decide your strategy?

[Grim Tuesday]

How does your team decide on the strategy you will be using for the game? Is it something pre-determined, something that a small council or subteam makes? Something your mentors do? Or is it a whole team decision?

I ask, because, in the past for our team, we have made it a whole team decision. This is getting quite unweildly, for our 50 person team, and has provided very little advantage (besides everyone is dedicated to the robot...but even then, it can be only 51%). We are curious as to what other teams have been doing, in the hope that we can update our process.
