This is the third lecture in the Introduction to Simple Design, covering one of Simple Design's two principles: reducing components. We'll examine what components are, why they should be reduced, and explore various methods for reducing components with example code. Additionally, we'll look at refactoring code smells, the concept of necessary waste from the Toyota Way, and discuss methods for evaluating your code quality skills.

This course is the second lecture in the Simple Design series. Simple Design proposes the following two methods for creating good code: 1. Remove duplicate code. 2. While doing so, find ways to reduce components. This lecture focuses on the first of these two methods.

Let's all consider whether good code's criteria are inherently subjective, and what considerations are needed for more objective evaluation.
