Simple Design Introduction - On Code Quality

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.

You will learn how to write clean code, which is essential for collaboration.

You can learn design patterns to implement flexible and scalable object-oriented programming. Learn various patterns that can be used in the real world and apply them to your projects and code refactoring.

I will transform the Engineer Information Processing written exam (Subjects 1–5) from a "test you solve by memorizing" into a "test where you connect clarified points directly to your score." This is an ultra-compressed lecture designed to help you grasp the entire flow within 3 days. It extracts only the core concepts repeated in past exams, structured to be understood even if viewed right before the test. The course is designed for short-term success by clearly distinguishing between frequently confusing concepts, trap points in multiple-choice options, and what needs to be memorized versus what only needs to be understood. "I'm short on time, but the scope is too broad." "I feel like I know the material when reading the book, but I keep getting the questions wrong." This lecture is for students facing these exact challenges.
