Essence of Decision--I : Models of Decision Making

[Updated to reflect that it's the first post of a series.]  Graham Allison and Philip Zelikow published a second edition of Essence of Decision: Explaining the Cuban Missile Crisi s in 1997. Some have called the first and second editions "classics", but it's not in print.  

Anyhow, just started reading the library's copy--they described three decision making models:

• Rational decision-maker: Model 1. What strikes me here is describing the nation as the decision-maker--i.e., why might the Soviet Union have decided to install missiles, etc.
• Organizational decision making. Model 2.  Where the focus is on the organizations involved in the decision makers, their processes, etc.--for example, DOD's perspective versus the Combined Chiefs versus the National Security council.
• Political decision making.  Model 3. Where the focus is more on the political maneuvering among the parties.

It's early days--looks as if I can renew the book a time or two. A couple things strike me already.  

1. We actually need a Model 0.5--the Black Box decision maker, also known as essentialism.  The Soviet Union was aggressively taking over the world, etc.
2. Not sure how the models relate to historians' descriptions of events--the narrative model.

We'll see.
