A chicken and a pig are walking down the road. Then conversation begins.
Chicken: "Do you want to open a restaurant with me?"
The pig considers the question and replies
Pig: "Yes, I'd like that. What do you want to call the restaurant?"
Chicken: "Ham and Eggs!"
The pig stops, pauses, and replies.
Pig: "On second thought, I don't think I want to open a restaurant with you. I'd be committed, but you'd only be involved."
In a project, there will be people who have committed to the project. Other might be interested in the project, but they aren't on the hook. Those who are responsible for the project have the authority to do what is necessary for its success. Those who aren't responsible can't interfere unnecesarily.from "Agile Project Management with Scrum by Ken Schwaber"
