Avoidnig the Flwas

Good advice on publishing in System Dynamics, and the invention of the Causal Slop Diagram

The SD Society is running a nice series on publishing. This is a topic I’ve written about several times:

Exactly what kind of SD diagram is that? Perhaps AI has invented Causal Slop Diagramming, or CSD for short? I particularly like how the magnifying glass creates discontinuities in spacetime.

The Rise and Fall of the Saturday Evening Post

Replicated by David Sirkin and Julio Gomez from Hall, R. I. 1976. A system pathology of an organization: The rise and fall of the old Saturday Evening Post. Administrative Science Quarterly 21(2): 185-211. (JSTOR link). Just updated for newer Vensim versions.

This is one of the classic models on the Desert Island Dynamics list.

There are some units issues, preserved from the original by David and Julio. As I update it, I also wonder if there are some inconsistencies in the accounting for the subscription pipeline. Please report back here if you find anything interesting.
