Jay Forrest ask about our experience making SD efforts last.

You can make SD work over time, if you want to do so. Management 
Information Systems have implicit rules which may determine behavior, 
because their implied policies drive the system elsewhere. John 
Morecroft developed principles relating SD models with Information 
Systems, which are useful to incorporate the model findings into the 
company operation. Levels mirror into files, rates mirror into computer 
programs, and policies command decisions. You have to align company 
resources with the implementation of the new policies. In the language 
of nonlinear dynamics, "we have to create a stable node around 
management objectives", without this effort, SD intervention may not 
last, because Information Systems, budgets and other endogenous 
influences also determine behavior.
