As a new Advancement Chair in our troop, I noticed our SM had WAAYYY too much control over who sat on Board of Reviews. Sometimes he would (bad, very bad). I started asking troop committee (TC) members to sit. Though they were untrained, I would start each BoR with the "reminder" that the BoR was to help evaluate the troop program, as well. It was the only time we could hear how a boy felt about his patrol, the troop, and the program adults (SM, SA).
We started asking the boys about the "best" parts and the "not-so-good" parts, and what he thought could improve the troop.
This started several interesting discussions with the SM. The committee realized some changes would be easy IF the committee stayed on task. The SM was more than willing to do some changes, and either gave lip-service or outright refusal about others. The TC could insist, but it would probably result in recruiting a new SM. The TC is not going to go there (today).
Upshot, the troop has improved, other improvments have at least been talked about, the TC members now want to be trained, and the boys are getting a little more excited.
So I advise small steps till you are ready to take a big leap.
Yours in Scouting,
Barry
P.S. I'm going to start a seperate thread about who, when, and where to select summer camp.
