… why you need models?
Models are necessary to communicate,
to stabilize abstractions
as a reference for the implementation
and maintenance
and you need an agreement on the notation and formalisms in which you
express your models

The Unified Modeling Language
(UML) resulted from a joint effort of
leading experts in object-oriented
analysis and design, Grady Booch,
Jim Rumbaugh and Ivar Jacobson,
also known as the three amigos, all
currently employees of Rational.

The UML toolbox is very rich. It
allows you to model every
conceivable aspect of the system.
Nevertheless, to my mind, graphical
models are not always appropriate.
But, on the other hand, most people
like them and they often make a
good impression, suggesting clarity
