If you have any interest in modelling domains, then you've probably already read, or are planning to read, Martin Fowler's Analysis Patterns. The models here share some overlap with that book, but this is a gentler introduction, so I would recommend this book for a beginner, before they read the Fowler book. A more experienced modeller should probably consider this as a catalogue of off-the-shelf models.

This book covers modelling enterprises - e.g. businesses and government agencies, and the relationships between their employees, organisational structures and the products and services they provide.

The fundamental models applicable to enterprises are covered here: the business itself, its employees and their positions; the products they produce and the equipment used to produce them; the activities carried out to produce the products; and the contracts between a buyer and seller that deliver the products and services. Later chapters cover some more specific examples, including accounting, laboratories, and manufacturing.

It is true that the models aren't very detailed, but that's the point of the book - for pretty much any enterprise, these models can be used as starting points, while covering most of the relationships that are likely to be encountered. It's true that you won't get any advice on actually converting the models to a database or an object oriented design, but that's beyond the scope of the book.

While an expert modeller won't find the in-depth treatment they might be looking for, I would definitely recommend this to a beginner. Unfortunately, there's no insight into the process of decomposing a domain, although the last chapter demonstrates wide applicability of the models by applying them to a theatre. What you do get are lots of simple examples of the finished output, which will provide inspiration, even if you have no particular interest in the enterprise domain itself.
