Cost of Quality Review
Is it worth paying for code review?
Paying a small amount for code review can be justified when the cost of shipping poor quality features is high.
- Investing in code review can save money in the long run.
- Shipping low-quality features can be costly.
- A small review cost can prevent larger issues.
Understanding Code Quality
What happens if you don't read the code?
Not reading the code leads to ignorance about its quality and potential issues.
- Lack of code review can result in hidden problems.
- Assuming models are sufficient without code review is risky.
- Awareness of code quality is crucial for reliable software.
Importance of Code Review
Why is reading code important?
Reading code is essential to assess its quality and ensure it meets standards.
- Code quality cannot be assumed without review.
- Understanding the codebase is key to delivering reliable software.
- Informed decisions about code quality require direct engagement with the code.
Efficient Code Review Practices
How much code should be read for reliability?
Read only the necessary amount of code to ensure software reliability within a large codebase.
- Focus on critical sections of code for efficient reviews.
- Not all code needs to be read to maintain quality.
- Strategic code review can enhance software reliability.
Engineer Performance and Code Quality
Do all engineers read code to ship quality software?
Not all engineers read all the code, yet companies can still function despite some shipping low-quality code.
- Quality varies among engineers; not all prioritize code review.
- Companies can operate with varying levels of code quality.
- Balancing efficiency and quality is a challenge in software development.

0:00 You're paying a thousand dollars per feature to ship slop. Is it worth it to pay like five dollars to review that slop? Probably. >> If you're not reading the code, you have no idea how much garbage is in your code. Like you can't say like, "Oh, we don't read the code. The models are good enough." No, you If you don't read the code, then you don't know. You like you cannot say that it's good or not.
0:18 >> Right there. >> Yeah, read the least amount of code you need to ship reliable software in a large enough code base. Your best engineers don't read all the code. Many more worse engineers ship slop all the time, yet companies work.
Summary
- Paying for code reviews is a worthwhile investment compared to the high cost of shipping poor-quality features.
- Not reading the code can lead to a lack of awareness about the quality and issues within the codebase.
- Reliable software requires at least some level of code review, even in large codebases.
- Top engineers may not read all the code, but they focus on critical areas to ensure quality.
- Many less experienced engineers contribute to poor code quality, yet companies continue to function.
- Understanding the code is essential for assessing its quality and reliability.
