If you’re at the top, decisions, ultimately, are up to you. 

Even if you’re leading a committee, or asking for feedback, if you can reject or approve a decision, at the end it’s up to you. 

You can go about owning the fact that you’re the end of the line and be transparent about it. This involves letting people know when you’ve made up your mind about a decision and that things are unlikely to change.

Or, you can continue to solicit feedback when nothing is going to change your mind, and you can tank your team’s morale at the same time by putting on the song and dance that you’re interested in their opinion when you really are not. 

One builds trust, the other erodes it. Choose.
