While I dont have a model reference to share, I think youd be on firm ground if you: - Defined the CRM problem you want to address or the purpose of the model (e.g., "Show how poor CRM leads to reduced customer satisfaction and eventually reduced profits") - Further specify the problem or ...

Ric, Does Law and Keltons _Simulation Modeling and Analysis_ help? It was on a frequently posted list of important (classic) books for simulation and modeling on the old comp.simulation group, as I recall. You might find it in your library (or at least through ILL), as you wanted a free resource. Bi...

J.J., It sounds like you may live in the Alsace (Strasbourg?); I used to live and work in the Black Forest. I like the region: Ive been hiking in the Vogesen and visited the chapel designed by Le Corbusier at Ronchamps. There are many German-language resources on SD. Check out http://www.uni-klu.ac....

Interesting discussion. Ive found 2 particularly easy situations in which communications on SD works, and lots more where it doesnt. First, easiest, and least likely to repeat, I once prepared a pitch to a 3rd level manager using an SD model to justify a business change to an organization. This mana...

Would a case of shifting loop dominance meet your criterion for learning? As one or more levels change in value, they may change the dominant loop in the system, and that would change the systems behavior over the longer term. See http://www.albany.edu/~gpr/LoopDom.pdf for a good discussion of that ...

For your second question, check out Alan Grahams PhD dissertation, "Principles on the relationship between structure and behavior of dynamic systems," 1977. You might also find http://www.albany.edu/~gpr/LoopDom.pdf of interest. Bill From: Bill Harris <bill_harris@facilitatedsystems.com> -...

Robert, A couple of thoughts. First, does it help to show the concept of money flowing into city coffers as a stock and flow (emphasis on the concepts, not the terms, of course)? In essence, the city wants (needs?) a certain flow of cash. Where is the flow coming from? If its coming from the same pe...

I think the "Big Three" all share that. What would be really nice, though, is an environment where all ones normal code development tools (e.g., emacs, cvs cs) were available. Then, as Tom suggested, one can do global search and replaces, one can use macros to create or modify multiple str...

George, Youve written about Unwarranted Criticism and now Leveraging the List-Serve. I like some of your points, but I have another perspective on what makes SD credible in the marketplace. Its only my perspective, not <<truth>>. I came into this field from an electrical engineering background, wher...
