Do these 3 things before closing this tab:

That gives both the author and reviewer less to reason about at once, and can make the change easier to review, merge, or roll back. I can’t claim personal experience, but this is a recommendation supported by Google Engineering Practices.
What does a small, self-contained change look like?
It addresses one thing rather than bundling several unrelated fixes or features into the same review. Google Engineering Practices describes the aim as: “The CL makes a minimal change that addresses just one thing.” A change can still include the code and related tests needed to deliver that behavior.

Think in terms of conceptual scope, not a fixed number of lines. A short change can still be hard to understand if its implications are unclear; a larger change may be coherent when its pieces are necessary to implement one focused outcome. Google’s Small CLs guidance recommends using judgment rather than treating line count as the definition of “small.”
Why can this help?
Google’s guidance says focused changes are easier to reason about and can be reviewed more quickly and thoroughly. They are also easier to merge and simpler to roll back; if a change is rejected, less work is at risk. These are engineering recommendations, not a controlled measurement showing that the habit boosts every developer’s productivity.

How to try the habit in your next review
- Choose one outcome. State what the change should do or fix. If the work contains independent concerns, consider separating them into distinct changes.
- Keep related tests with the code. When a logic change introduces or alters behavior, include the relevant new or updated tests in the same focused change.
- Check whether the whole change tells one story. Ask whether a reviewer can understand the purpose and implications without tracking unrelated work. If splitting it would make the pieces harder to understand, keep the necessary context together.
Why this is a habit to adapt, not a universal rule
Developers’ workdays depend on context, and a single workflow prescription will not fit everyone. Microsoft Research’s 2019 study, “Today was a Good Day: The Daily Life of Software Developers,” analyzed 5,971 responses from professional developers at Microsoft about good or typical workdays. It identified agency—how much control developers have over their work and whether the day goes as planned—as an important factor, and recommends that managers empower developers to choose tools and tasks where possible. The study did not test whether small code changes cause better workdays or higher productivity.
Use the small-change approach where it fits your team’s review process. The goal is not to minimize every diff; it is to make the purpose and consequences of each change easier to understand.
