Notes From "Practical Object-Oriented Design In Ruby" by Sandi Metz
View poodir-notes.md

Chapter 1 - Object Oriented Design

The purpose of design is to allow you to do design later, and it's primary goal is to reduce the cost of change.

SOLID Design:

  • Single Responsibility Principle: a class should have only a single responsibility
  • Open-Closed Principle: Software entities should be open for extension, but closed for modification (inherit instead of modifying existing classes).
  • Liskov Substitution: Objects in a program should be replaceable with instances of their subtypes without altering the correctness of that program.
  • Interface Segregation: Many client-specific interfaces are better than one general-purpose interface.

AGILE ESTIMATING AND PLANNING

Mike Cohn

CHAPTER 1. The Purpose of Planning

Plans help to guide investment decisions (this project is worth to begin?), know who needs to be available to work on a project during a given period and know if a project is on track.
