What is essential for planning an effective code review?

• A. Define goals, focus on design and correctness first, provide concrete suggestions, avoid personal critique, and balance positive feedback with issues; ensure actionable, prioritized items.
• B. Define goals, focus on design and correctness first, provide personal critique only, and minimize actionable items.
• C. Focus on syntax errors and style violations only.
• D. Delay feedback until after deployment.

Answer: (A)

Clear goals and a structured approach guide an effective code review. Start by defining what success looks like for the review—whether the aim is to improve design, verify correctness, or boost maintainability. Then tackle design and correctness first, so architectural and logical issues are addressed before getting bogged down in minor details. Feedback should include concrete suggestions, not vague critiques, giving the author a clear path to fix things with examples or references.

Maintain a constructive tone by focusing on the code rather than the person, avoiding personal critique. Balance praise for what’s well done with highlighting issues, so motivation is preserved while important problems are surfaced. Finally, ensure feedback items are actionable and prioritized, enabling the team to triage and plan fixes, starting with the most impactful.

This combination helps the review stay useful, guiding improvements early and increasing the likelihood that the codebase becomes more robust and maintainable. The other options don’t fit as well because they either emphasize only personal critique, restrict focus to syntax and style, or delay feedback until after deployment, which misses opportunities to prevent defects and guide better design.
