Collaborative derivation of an interface and partial implementation of programming code

A method, system and computer program product provide an implementation of software. A control flow of a software component is constructed based on a specification model. In various embodiments, the specification model comprises at least one input and at least one requirement referencing the at least one input. At least a partial implementation of the software component is generated based on the control flow and the at least one input and the at least one requirement of the specification model. In some embodiments, the specification model further comprises at least one output, and the at least a partial implementation of the software component is also based on the at least one output.
