The fable of the Chicken and the Pig is used to illustrate the differing levels of project stakeholders involved in a project. The basic fable runs：
A Pig and a Chicken are walking down the road.
The Chicken says: “Hey Pig, I was thinking we should open a restaurant!”
Pig replies: “Hm, maybe, what would we call it?”
The Chicken responds: “How about ‘ham-n-eggs’?”
The Pig thinks for a moment and says: “No thanks. I’d be committed, but you’d only be involved.”
Sometimes, the story is presented as a riddle:
Question: In a bacon-and-egg breakfast, what’s the difference between the Chicken and the Pig?
Answer: The Chicken is involved, but the Pig is committed!
