## Short answer

In performance reviews, describe colleagues with precise trait words plus evidence. Prefer “diligent,” “methodical,” “astute,” or “collaborative” over vague “good” or loaded “stubborn.” Pattern: trait + example + impact—“She’s methodical: she caught the null-pointer case in review, which prevented a prod incident.” For growth areas, stay behavioural and future-focused: “He can improve stakeholder updates by sharing risks earlier,” not personal labels.

## Why Word Choice Matters in Performance Reviews

When you write a 360-degree review or give sprint feedback, every word carries weight. Calling someone 'resolute' signals a strength; calling them 'stubborn' flags a problem. Both describe someone who doesn't change their mind easily — but the connotation is completely different.

In tech workplaces, written feedback lives in HR systems for years. Choosing vocabulary carefully protects your colleague's reputation and demonstrates your own communication maturity.

> **Culture Note: Direct vs. Diplomatic Feedback:** In many Western tech companies, feedback is expected to be direct but constructive. However, 'direct' doesn't mean 'harsh.' A phrase like 'tends to be tactless in code reviews' is too blunt for most performance docs. Try: 'Could benefit from more diplomatic phrasing when giving feedback.'

## Positive vs. Negative Trait Vocabulary for Engineers

Many personality traits exist on a spectrum. The same behavior can be framed positively or negatively depending on your word choice. Use the table below to select vocabulary that matches your intended message.

| Positive Framing | Negative Framing | What It Describes | Tech Example |
| --- | --- | --- | --- |
| diligent, industrious | work-obsessed, workaholic | works very hard | She's diligent about testing edge cases vs. He's work-obsessed and burns out teammates |
| resolute, dogged | stubborn, obstinate | doesn't give up easily | He was resolute in debugging the memory leak vs. She's stubborn and won't consider alternative approaches |
| shrewd, astute | cunning, sly | makes clever decisions | Our PM is astute at prioritizing features vs. He's cunning about taking credit for team wins |
| methodical, conscientious | inflexible, dogmatic | careful and systematic | She's methodical in her code reviews vs. He's inflexible about coding standards |
| thrifty, frugal | stingy, parsimonious | careful with resources | The team is frugal with cloud costs vs. Management is stingy with the training budget |
| witty, pithy | brusque, terse | speaks concisely | Her RFC summaries are pithy and clear vs. His Slack replies are brusque and feel dismissive |

> **Grammar Tip: Adjective + Preposition Patterns:** Many trait adjectives take specific prepositions. Learn these patterns: 'diligent about (quality)', 'astute at (skill)', 'tolerant of (difference)', 'supportive of (colleagues)'. Wrong prepositions sound unnatural: *'She is diligent at testing' → 'She is diligent about testing.'

## Scenario 1: Writing a 360-Degree Performance Review

In 360 reviews, you describe a colleague's strengths, growth areas, and impact. Avoid vague words like 'nice' or 'good.' Use specific vocabulary paired with evidence.

| Weak / Vague | Strong / Specific |
| --- | --- |
| She is a good engineer. | She is a methodical engineer who consistently catches edge cases in code review. |
| He is bad at communication. | He tends to be brusque in written feedback, which can feel dismissive to junior engineers. |
| She works too much. | She is diligent to a fault — I'd encourage her to delegate more to avoid burnout. |
| He's nice to work with. | He is obliging and supportive — always willing to unblock teammates during on-call rotations. |

- obliging — ready to help others; willing to do favors
- supportive — gives encouragement and practical help
- altruistic — puts team needs above personal recognition
- conscientious — takes responsibilities seriously; thorough
- down-to-earth — practical, sensible, not pretentious

## Scenario 2: Giving Structured Feedback After a Sprint

Sprint retros and 1:1s require real-time feedback vocabulary. You need phrases that are honest but constructive. Here's how to reframe negative traits diplomatically.

| Heard at Work (Too Direct) | Better English (Diplomatic) |
| --- | --- |
| You got carried away with the refactor and missed the deadline. | You're enthusiastic about code quality — let's discuss scoping refactors to stay on timeline. |
| You're stubborn about your technical opinions. | You're resolute in defending your architecture choices. Could you also explore alternatives the team suggests? |
| Your Slack messages are terse and rude. | Your messages are efficient, but adding context would help the team understand your reasoning. |
| You're a perfectionist and it slows us down. | Your attention to detail is valuable. Let's calibrate what 'good enough' looks like for MVP features. |

> **Phrase Pattern: [Positive Trait] + 'Let's discuss [growth area]':** This pattern acknowledges strength before addressing growth: 'You're intuitive about user needs — let's discuss how to document that intuition in your design docs so others can learn from it.'

## Scenario 3: Describing a Candidate to a Hiring Panel

When debriefing after interviews, your vocabulary shapes hiring decisions. Be precise about strengths and concerns. Avoid words that sound biased or unprofessional.

| Trait to Describe | Professional Vocabulary | Example Sentence |
| --- | --- | --- |
| Good instincts | intuitive, astute | She was intuitive about system design trade-offs without needing detailed prompts. |
| Very experienced | shrewd, seasoned | He's a shrewd debugger — he isolated the race condition in minutes. |
| Friendly personality | magnetic, personable | She has a magnetic presence that would energize the team. |
| Lacks confidence | insecure, uncertain | He seemed insecure when defending his design choices under pressure. |
| Overconfident | tactless, dismissive | She was tactless when the interviewer challenged her assumptions. |
| Inexperienced | naive, green | He's a bit naive about production scale, but trainable. |

- intuitive — understands things instinctively without needing explanation
- magnetic — has a personality that naturally attracts and engages others
- tactless — says things that unintentionally upset or offend people
- naive — lacks experience; trusts too easily
- insecure — not confident; uncertain about own abilities

## Register: Slack vs. Performance Documents

The same trait needs different vocabulary depending on where you're writing. Slack tolerates casual language; performance docs and hiring feedback require professional register.

| Meaning | Casual (Slack / Chat) | Formal (Docs / Reviews) |
| --- | --- | --- |
| Works very hard | She's a total workhorse | She is exceptionally diligent |
| Practical, sensible | He's super down-to-earth | He takes a pragmatic, grounded approach |
| Helps others | She's always got your back | She is reliably supportive and obliging |
| Talks too much | He rambles a lot | He can be somewhat verbose in meetings |
| Makes clever decisions | She's sharp | She demonstrates shrewd judgment |

## FAQ

### How do I describe a colleague who is stubborn without sounding rude in a performance review?

Replace 'stubborn' with positive-frame alternatives like 'resolute,' 'principled,' or 'steadfast'—then add evidence and impact. Example: 'He is resolute in his technical decisions; he pushed back on a risky database migration, which protected our stability.' If you must note inflexibility as a growth area, use behavioral language: 'She can improve by soliciting peer input earlier in the design phase,' not 'She is stubborn.' This protects your colleague's reputation while keeping the feedback actionable and professional.

### What's the difference between 360 review language and how I talk to a colleague in Slack?

360 reviews and formal performance documents require elevated, precise vocabulary—use trait words like 'meticulous,' 'proactive,' or 'astute' with specific examples. Slack allows casual phrasing like 'great catch on that bug' or 'you crushed that deadline.' In 360 reviews, write 'She demonstrated exceptional attention to detail by identifying edge cases in the payment flow,' whereas in Slack you might say 'Nice work spotting that edge case!' Always match your register to the document's permanence: HR systems demand professional vocabulary that will protect both you and your colleague.

### How do I give negative feedback about an engineer's performance without damaging their reputation?

Frame growth areas behaviorally and future-focused, not as character flaws. Instead of 'He lacks communication skills,' write 'He can improve stakeholder alignment by sharing progress updates twice weekly' or 'She would benefit from documenting decisions earlier in the sprint.' Use this pattern: specific behavior + impact + clear improvement action. Avoid loaded words like 'lazy,' 'careless,' or 'difficult'; instead use 'can prioritize,' 'would benefit from a checklist,' or 'can collaborate more actively.' This approach signals professionalism and helps your colleague improve without creating a negative permanent record.

### What vocabulary should I use when describing a colleague to a hiring panel after an interview?

Use precise, evidence-backed trait vocabulary without bias: 'methodical,' 'collaborative,' 'detail-oriented,' or 'innovative.' Always pair traits with concrete examples: 'She is methodical—she walked through her debugging approach step-by-step and caught the root cause quickly.' Avoid vague words ('nice,' 'good') and subjective judgments ('she seemed nervous'). For concerns, use professional language: 'His system design approach could be more scalable' rather than 'He's not a strong architect.' This vocabulary demonstrates your credibility to the hiring panel and ensures fair, bias-resistant candidate feedback.

### How do I follow up or correct feedback I gave about a colleague that might have sounded too negative?

If your feedback was too harsh, request a brief follow-up conversation with the recipient and reframe it constructively: 'I want to clarify—what I meant was that you have the opportunity to improve X by doing Y.' Resubmit written feedback if it's still in draft form in your HR system. Use this template: acknowledge the original statement + reframe with positive intent + provide actionable path forward. Example: 'When I said you need to improve documentation, I meant: your technical work is solid, and adding more detailed comments would make code reviews faster for the team.' This shows maturity and protects both your professional reputation and engineer performance relationships.
