Abstract

See full text

Example methods and apparatus to modify a recipe process flow during recipe execution are disclosed. A disclosed example method involves executing a recipe, and before completion of execution of the recipe, receiving process flow change information indicative of a modification to a process flow of the recipe. Process flow rules are then retrieved from a process flow rules data structure. The recipe process flow is modified based on the process flow change information in response to determining that at least one requested change indicated by the process flow change information does not violate one of the process flow rules.
