Smalltalk Best Practice Patterns in Ruby

1 – INTRODUCTION

• We aren’t always good at guessing where responsibilities should go. Coding is where our design guesses are tested. Being prepared to be flexible about making design changes during coding results in programs that get better and better over time.
