Few moments in an engineering researcher’s career test both technical skill and emotional composure like opening a set of reviewer comments. While the instinct may be to brace for criticism, each comment is an opportunity to sharpen your argument, strengthen your data, and align your work more closely with the standards of your field. Approaching feedback constructively is not a passive exercise—it is a deliberate process that can transform a borderline manuscript into a accepted publication. This guide offers a framework for addressing reviewer comments in engineering research with clarity, professionalism, and strategic rigor.

Understanding the Reviewer’s Perspective

Engineering journals rely on peer reviewers who volunteer their time to ensure that published research is sound, reproducible, and a meaningful contribution. Reviewers read your manuscript with the goal of identifying weaknesses—not to attack you personally, but to uphold the quality of the literature. Their comments often fall into one of several categories: requests for clarification, methodological concerns, missing data or controls, insufficient contextualization, and suggestions for additional experiments. Recognizing this intent makes it easier to respond without defensiveness and to see feedback as a collaborative refinement of your work.

A useful first step is to read all comments once without taking any action. This allows you to absorb the overall tone and spot recurring themes. After the first pass, go back and label each comment by type: “data missing,” “clarity needed,” “methodology question,” “reference required,” and so on. Grouping comments helps you identify which revisions are truly major and which are minor adjustments.

Preparing a Systematic Response Plan

Begin by creating a document that lists every reviewer comment verbatim, leaving space for your response and a summary of the change made to the manuscript. This response letter will be submitted alongside the revised manuscript. A systematic approach prevents missing any item and demonstrates to the editor that you have taken each comment seriously.

Prioritize Revisions

Not all feedback carries the same weight. Some comments—such as “add error bars to Figure 3” or “clarify the assumption of linearity in your model”—are straightforward and can be completed quickly. Others, like “the experimental setup lacks a control condition under variable load” or “you should compare your algorithm against state-of-the-art methods in a head-to-head benchmark,” may require new experiments, simulations, or data collection. Separate these into “quick fixes” and “substantial revisions,” then schedule time accordingly. Substantial revisions often benefit from input from coauthors or colleagues before you begin.

Address Every Item, Even to Disagree

You are not obliged to accept every suggestion. Engineering reviewers sometimes propose experiments that are infeasible, irrelevant, or based on a misunderstanding of your approach. In such cases, you must politely explain why you disagree and provide evidence to support your reasoning. For example, if a reviewer asks for a field test that would take six months and your journal deadline is two weeks, you can explain that while the test is valuable, it exceeds the scope of this particular study—and then propose an alternative validation method. Editors appreciate reasoned disagreement far more than ignoring a comment.

Writing the Response Letter

The response letter is arguably as important as the revised manuscript itself. Editors and reviewers often read it first to see how you engaged with the feedback. Structure the letter clearly: start with a brief thank-you and an overview of the major revisions, then list each reviewer’s comments (numbered for clarity), followed by your response and a description of the change. Use bold to separate the reviewer’s comment from your reply, or use a table.

Reviewer 1, Comment 2: “The authors assume the material behaves elastically under all loading conditions, but this is not justified for the high-temperature regime studied.”
Response: We thank the reviewer for this important observation. We have now added a section (Section 4.2, lines 210–225) that discusses the temperature-dependent transition from elastic to viscoelastic behavior and provides references (Ashby and Jones, 2006; Lakes, 2009) that support this transition. Additionally, we have included a new figure (Figure 7) showing stress-strain curves at three temperatures to demonstrate that the elastic assumption holds only below 150 °C. The manuscript has been revised accordingly.

Each response should be self-contained so the reviewer does not have to flip between documents. If a comment inspired a large change, refer the reviewer to the exact page and line numbers (or section) where the change appears. For minor edits, simply state, “We have revised the sentence as suggested (see page 5, line 132).”

Making Revisions Transparent in the Manuscript

Do not assume that reviewers will re-read the entire paper. They expect you to highlight changes. Common methods include using a different font color (e.g., blue or red text for new content), “track changes” in a word processor, or adding marginal comments like “revised for clarity”. Some journals require a separate “clean version” and a “marked version”. Check the journal’s guidelines before you begin. The goal is to make every alteration easy to locate without having to re-read the whole manuscript.

Handling Specific Types of Feedback

Requests for Additional Experiments

When a reviewer asks for new tests, first evaluate whether the experiment is truly necessary to support your conclusions. If the data you already have are sufficient, explain why and point to existing evidence. If the request is reasonable but time- or resource-intensive, propose a practical substitute. For example, if asked for a long-term durability test, you could present accelerated aging results or cite relevant standards that predict long-term behavior. Always couple your response with a clear justification and a reference to the change made in the manuscript.

Methodological Criticism

Critiques of your methodology often strike at the heart of your study. Treat these with respect, even if you believe the reviewer is mistaken. Start by restating your method, then address the concern. If the reviewer points out a genuine flaw—say, an inappropriate control group—do not defend it; instead, explain how you have corrected it. If the criticism is based on a misunderstanding, clarify your protocol in a revised section and cite supporting literature to validate your approach.

Requests for Additional Literature

When a reviewer suggests references, treat every suggestion seriously. Even if the reference seems tangential, including it can strengthen your context and show that you have engaged with the field. If a reviewer asks for a comparison with a specific prior work, add a short discussion in the relevant section. If you believe the reference does not apply, explain why gently—for example, “We considered the work of Chen et al., but it addresses a different class of materials; we have added a note in the Introduction clarifying the boundaries of our study.”

Minor Comments (Grammar, Formatting, Clarity)

These are the easiest to address and should be handled quickly. Even a single, optional grammatical suggestion should be accepted unless it introduces an error. Accepting minor fixes builds goodwill and shows you are attentive.

Not all submissions proceed to acceptance. A “revise and resubmit” with major changes or even a rejection can be disheartening, but many great papers have been rejected by one journal before being accepted at another. The key is to treat rejection as data: examine the comments to see if they point to fundamental flaws (e.g., insufficient novelty, poor methodology) that need to be addressed before resubmitting elsewhere. If the editor suggests resubmission after major revisions, treat that as an invitation, not a rejection. For a manuscript that is rejected without review (desk reject), often the most common reasons are lack of novelty, misalignment with the journal’s scope, or poor presentation. In that case, rework the narrative and choose a more appropriate venue.

When a paper is rejected with reviews, read those reviews carefully. The same comments may arise at the next journal if you do not fix them. Address each issue in your revision, even if you plan to submit to a different journal. Write a new cover letter that explains what has been changed and why the work now fits the new journal.

Practical Tools and Resources

Maintaining Professionalism Through the Process

Engineering research is a collaborative endeavor. Reviewers, editors, and authors share the goal of advancing knowledge. Maintaining a respectful tone, even when a comment feels off-base, is not only ethical but practical: a hostile response can turn a reviewer against your work and delay publication. Always thank the reviewer for their time and insight, even when disagreeing. Use phrases like “We appreciate the reviewer’s suggestion and have carefully considered it. In our context, however, we believe that…” such language shows respect while preserving your scientific position.

Keep a record of all correspondence. If a reviewer misinterprets your response, you can refer back to the original comment. Also, work within the journal’s deadlines; late submissions can lead to a rejection or require you to start the review process anew. If you need more time, request an extension early—most editors grant one if you have a plausible reason and have shown progress.

Addressing reviewer comments constructively is a skill that improves with practice. Each round of revision teaches you how to anticipate criticism, communicate technical decisions, and advocate for your contributions. By treating feedback as a dialogue rather than a verdict, you not only improve your manuscript but also strengthen your own growth as an engineering researcher. The final product—a published paper that has been improved by the scrutiny of peers—is a testament to the power of collaborative scholarship.
