e is only ready for the oven (ei. bargaining table) by the group when they have all added their own ingredients, and come to a resolution on these ingredients and the level of each. Once this is done, then it is time for external negotiations. I will use the cooking of a pie as a simile for the bargaining process to outline my views. In this way I hope to outline the reasons as they are presented in the article in my own way as I understand and agree with them.

Just as one doesn't add more ingredients to a pie after it's put in the oven, internal bickering within a group of what should have or shouldn't have gone into the pie has no place in the negotiations with the other party. Sure it is possible to change the ovens cooking time and even add new ideas to the pie before entering the oven, if that is what is needed to form an agreement.
