Suppose we are designing a system to automate some business process. We analyze the process, identify the concepts, model the process, design a solution, implement the design and install the software. Now the business process is no longer what the model represented. The process has been altered by people using the software.
Suppose we are modeling some business process. In the model, a message goes from an A object to a B object. We implement the model. The software is now a concept in the domain. Call this concept S. The same message goes from an A object to an S object to a B object. Is S part of the solution?
A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi
Whenever you add software to a problem domain, the behavior in that problem domain changes. So the model no longer reflects the problem domain.

Well maybe I am way off track. It seems not to be a familiar idea. There must be a bug in my perspective.
The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you do is who you become. Your integrity is your destiny - it is the light that guides your way. - Heraclitus
Is it as simple as thinking of "before and after" models? I wouldn't try to get both states into one model.
