The general methodology to use Smalltalk
Last updated at 4:43 pm UTC on 16 January 2006
The methodology to use Smalltalk consists of four steps:

1. Identify objects that appear in the problem and in its solution.

2. Classify these objects based on their differences and similarities.

3. Design the messages that will constitute the language of interaction between the objects.

4. Implement the methods by means of algorithms that carry out the interaction among objects.

(From the preface of the Blue Book)
