As I was reading it, one thought stood out clearly. And that relates to an earlier post I made about flowcharts.
Chapter 4 puts my thoughts of a good model quite articulately (quoting Marshal Clemens from Ideagram). Namely they should be
- Salient - only include detail that is relevant to the task at hand.
- Accurate - it should reflect the correct state of affairs, not a biased or incorrect view.
- Complete yet Parsimonious - it should be simple as possible, but no simpler
- Understandable - it should not be too complicated for the reader to understand. Any assumed knowledge should be indicated.
