The business fable of The Chicken and the Pig is about commitment to a project or cause. When producing a dish made of ham and eggs, the pig provides the ham which requires his sacrifice and the chicken provides the eggs which are not difficult to produce. Thus the pig is really committed in that dish while the chicken is only involved, yet both are needed to produce the dish.
