Try making each code change self-contained and focused on one concern. A reviewer—and you—have less to understand at once, and the change is easier to assess and manage. That is a practical recommendation, not a claim that every developer will see the same results.
What the habit looks like
Before submitting a change, check whether it addresses one coherent concern. Keep the code and the relevant tests together when they implement or verify that behavior. If the work also includes an unrelated cleanup or feature, consider separating it into another change.
Google Engineering Practices describes the goal this way: “The CL makes a minimal change that addresses just one thing.” Here, “CL” means a change submitted for review. The guidance recommends including related tests when appropriate and says logic changes should have new or updated tests for the new behavior. Google Engineering Practices: Small CLs

A focused change gives a reviewer a clearer question to answer: does this particular change do what it is meant to do? Google’s guidance says small changes can be reviewed more quickly and thoroughly, are easier to reason about and merge, and are simpler to roll back. Those are reasons to try the practice, not a measured guarantee of faster work or fewer defects.
The same focus helps the author explain the intent and understand feedback. If a change is rejected or needs revision, less unrelated work is tied up with it.
How small is small?
Think in terms of conceptual scope, not a fixed number of lines. A change can touch many lines and still address one concern; a handful of lines can combine unrelated ideas. Google’s guidance cautions against making a change so tiny that its implications become hard to understand. Use judgment: the goal is a coherent unit that can be reviewed on its own, not the smallest possible diff.
Make it a repeatable check
- Name the purpose. Summarize the intended behavior or fix in one sentence.
- Check the scope. Separate unrelated cleanup or follow-on work where doing so keeps each piece understandable.
- Keep verification with the change. Include relevant new or updated tests when they belong to the behavior being changed.
- Review it as a reader. Ask whether someone can understand the change’s purpose and implications without tracing unrelated work.
Keep the advice in perspective
There is no single workflow habit that suits every developer or team. A 2019 Microsoft Research study, based on 5,971 responses from professional developers at Microsoft about good or typical workdays, identified developer agency—the degree of control people have over their workday and whether it goes as planned—as an important factor. It did not test whether small code changes improve productivity. Microsoft Research: Today was a Good Day: The Daily Life of Software Developers
