A method, system, and computer-readable medium for staged validation of work packets within a software factory are presented. In one embodiment, the method includes creating a preliminary work packet. A validation constraint is appended to the preliminary work packet to create a constrained work packet. The constrained work packet is submitted to the software factory, within which the validation constraint is validated at different stages to confirm that the validation constraint is proper for the constrained work packet. If a validation result fails to meet all requirements of the validation constraint at each stage, the validation constraint is resolved, and the constrained work packet is re-submitted at that stage.
