  1. Code Review Disagreements occur when a software engineer's proposed changes to an existing codebase during a code review are not well-received by a colleague.

  2. The colleague may strongly believe that their original approach is more efficient, leading to a conflict of ideas.

  3. This can lead to discord, negatively affect team cohesion, and hinder progress if not addressed constructively.


  1. Open Dialogue - Engage in open, respectful dialogue about the disputed code. Understand the other person's point of view and explain yours clearly.

  2. Quantitative Measures - Utilize performance metrics or testing to demonstrate the efficiency of your solution.

  3. Involve a Third Party - If agreement cannot be reached, involve a neutral third party such as a team lead or a senior developer for their perspective.

  4. Compromise - Be willing to compromise. If the disagreement isn't critical, adopting your colleague's approach might foster goodwill and cooperation.

  5. Continuous Learning - Use disagreements as opportunities to learn and grow. You can always learn something new from these discussions.

Effective use

A software engineer successfully resolves a Code Review Disagreement by effectively communicating their thoughts about the proposed changes, providing clear and rational explanations, and being open to counter-arguments. They employ testing tools to gather performance data supporting their stance. When the disagreement persists, they involve a team lead to mediate and provide input. They display willingness to compromise when it benefits team cohesion and project progression, treating the whole experience as a chance for continuous learning.


Ineffective resolutions to a Code Review Disagreement might include resorting to personal attacks, stubbornly refusing to consider the other's perspective, dismissing the disagreement without discussion, or escalating the issue to higher management without first trying to solve it within the team.
