Pigs Talk and Chickens Listen

One important element of Scrum is the people involved gets to take the decision.

The story goes that the pig and the chicken got together to give a feast to the farmer. And it was suggested to give Ham and Egg. On deciding whether to go ahead to do this or not, its the pig that has the say since he's "committed" and the chicken has no or little say since he's "involved".

So comes, only pigs have the say.

It follows, that its the project team that actually does the work has a say during the project team discussions on committing work. Not the chicken, like the management, who are only involved.
