The adaptability in complex software systems

The first step in development of complex software system is to model the properties of target system. An evolution of software system starts already in human mind in the form of abstract ideas. The programmer tries to express these abstract ideas in the form of running software system using one of existing modeling tools and paradigms. But with a time, ideas about approach that was used during system development lose and we have only conception of target solution. If there are some changes to software system, the system is not able to generate the concept of its changes to a human. There is a question, how it is possible that system creates the concept of itself to a human? Our idea is that the system can create such concept through the model that the human will be able to adapt and make changes to a system.
