Research: Performance Reviews That Actually Motivate Employees
Forget the Dread — Performance Reviews Can Motivate. Here’s the Research to Prove It
In Harvard Business Review’s article “Research: Performance Reviews That Actually Motivate Employees,” authors Joonyoung Kim and Emily Zitek examine how different performance-review formats affect employees’ sense of fairness and motivation. Published November 7, 2024, the article is based on a study of 1,600 U.S. workers comparing reactions to narrative feedback, numerical feedback, and a combination of both.
For business leaders, the article addresses a practical performance-management question: should organizations use numbers, written feedback, or both? The answer is nuanced. Narrative feedback is generally perceived as fairer because it provides context, examples, and a more personalized path for improvement. Numerical feedback can still be useful, especially when employees need clear benchmarks or when ratings are directly tied to rewards.
Executive summary for business leaders
Overarching theme: Performance reviews motivate employees when they feel fair, specific, and useful. Kim and Zitek’s research suggests that narrative-based feedback can be especially powerful because employees see it as more personalized and more informative than a number alone. Written comments help employees understand what they did well, where they need to improve, and how to move forward.
The article does not argue that organizations should eliminate numerical ratings entirely. Numbers can provide clarity, comparability, and performance benchmarks. But when used alone, numerical ratings may feel impersonal, reductive, or insufficiently explanatory. The strongest performance-management systems are likely to combine the clarity of numbers with the developmental value of narrative feedback.
Major takeaways
1. Performance reviews are still important
Despite widespread frustration with annual reviews, the article starts from the premise that performance reviews remain a key tool for motivating and engaging employees. The question is not whether feedback matters, but how feedback should be delivered so employees experience it as fair and useful.
Business implication: Leaders should not abandon performance reviews without replacing them with a better system for feedback, development, accountability, and recognition.
2. Narrative feedback feels more fair
The study found that narrative feedback is generally perceived as fairer than numerical feedback. Written comments give employees more detail, context, and explanation, helping them understand the reasoning behind the evaluation.
Business implication: Employees are more likely to accept feedback when they can see the logic behind it. A rating without explanation can feel arbitrary, even when it is accurate.
3. Narrative feedback is especially helpful for employees with room to improve
The article highlights that narrative feedback can be especially meaningful for employees who need development. A number may tell someone they are underperforming, but written feedback can explain what needs to change and how to improve.
Business implication: Managers should not rely on low ratings alone to drive improvement. Employees need concrete examples, behavioral guidance, and a clear path forward.
4. Numbers provide clarity and benchmarks
Numerical feedback still has advantages. Ratings can help employees understand where they stand, compare performance against expectations, and track progress toward specific targets.
Business implication: Numbers can be useful when employees need clear standards, measurable goals, or transparent links to compensation and promotion decisions.
5. Numbers alone can feel reductive
A numerical score can oversimplify complex work, especially in roles where performance depends on collaboration, judgment, creativity, customer relationships, leadership behavior, or long-term contribution.
Business implication: Leaders should be careful when reducing performance to a single score. The more complex the work, the more important context becomes.
6. Combining narrative and numerical feedback may offer balance
The article explores whether one format — narrative, numerical, or both — is best. The practical implication is that combining both can give employees clarity and context: a rating that sets the benchmark and narrative comments that explain the evaluation.
Business implication: A balanced review can answer three questions: Where do I stand? Why did I receive this assessment? What should I do next?
7. Fairness drives motivation
Employees are more likely to feel motivated when they believe the review process is fair. Perceived fairness depends not only on the outcome of the review, but also on whether the feedback is specific, transparent, and connected to real behavior.
Business implication: Performance-review design should focus on employee trust. A technically efficient system that employees distrust will not motivate sustained improvement.
8. Managers need to write better feedback
Narrative feedback is only valuable when it is thoughtful. Generic comments such as “great job” or “needs improvement” do little to motivate or develop employees. Effective narrative feedback is specific, behavior-based, balanced, and actionable.
Business implication: Organizations should train managers to write feedback that includes examples, impact, expectations, and next steps.
9. Reviews should support development, not just evaluation
The article reinforces that performance reviews should do more than classify employees. They should help people understand how to grow, improve, and contribute more effectively.
Business implication: Reviews should be connected to coaching, goal setting, learning plans, career development, and ongoing check-ins.
10. The best format depends on the purpose
Performance reviews serve multiple purposes: development, compensation, promotion, documentation, recognition, and accountability. A narrative-heavy format may be best for development, while numerical ratings may be useful for compensation or calibration.
Business implication: Organizations should not design one review format and expect it to serve every purpose equally well. The review format should match the decision being made.
Leadership talking points
Performance reviews motivate employees when they are perceived as fair, specific, and actionable.
Narrative feedback gives employees context and a path for improvement.
Numerical ratings can provide clarity, but they should rarely stand alone.
Employees with room to improve need more than a score; they need examples, coaching, and next steps.
The goal of a review is not simply to judge performance, but to help employees perform better.
Managers need training in writing and delivering feedback, not just completing forms.
A good review answers: What happened, why it matters, where I stand, and what I should do next.
Reflection questions
Do our performance reviews help employees improve, or mostly document what already happened?
Are employees receiving enough narrative feedback to understand the reasoning behind their ratings?
Where are we over-relying on numbers to evaluate complex work?
Are managers writing specific, behavior-based feedback, or generic comments?
Do employees believe our review process is fair?
Are underperforming employees receiving clear guidance on what must change?
Do high performers receive enough detail to understand what excellence looks like and how to keep growing?
Are performance reviews connected to coaching, development, compensation, and career conversations in a coherent way?
Potential action items
Review your current performance-review form and determine whether it overemphasizes ratings at the expense of useful narrative feedback.
Require managers to include specific examples of behaviors, outcomes, and impact in written reviews.
Use numerical ratings only where they clarify standards, support calibration, or connect transparently to rewards.
Train managers to write feedback that is specific, balanced, evidence-based, and actionable.
Create separate spaces in the review for performance assessment, development goals, career aspirations, and manager support.
Ask employees whether they find reviews fair, useful, and motivating.
Add follow-up check-ins after performance reviews so feedback turns into behavior change.
Provide managers with sample language for difficult feedback, especially for employees who need improvement.
Clarify how performance reviews connect to compensation, promotion, recognition, and development.
Audit review quality across departments to identify vague, inconsistent, or biased feedback patterns.
