The complete guide to running performance reviews at a growing company
Growing companies between 50 and 100 people can run a full performance review cycle in under two weeks. Use continuous accomplishment tracking so reviews are based on evidence, not memory. Include self, peer, and manager reviews, keep the structure consistent every cycle, and close with a calibration step. WorkSpark runs this out of the box at $4 per user per month, no templates to build.
Performance reviews at a 20-person company are easy: the founder has seen everything. At 50 to 100 people that stops being true. Managers lose visibility into work outside their own team, high performers go unnoticed, and review time becomes a scramble to reconstruct six months of memory.
This guide walks through a review process that works at this size, without spreadsheets and without a three-month rollout.
Start with a continuous record, not a blank page
The single biggest flaw in most review processes is that they ask reviewers to write from memory. Nobody remembers 90 days of work accurately. What people remember is the last two or three weeks, which is exactly why reviews end up biased toward whatever happened most recently.
Accomplishment tracking fixes that. Ask every employee to log what they accomplished on a regular basis, in a form built around one question: what did you accomplish? A short description is all that is required. Over a quarter, those entries become a record that feeds directly into the review.
When the record exists, self-reviews and manager reviews are written against evidence rather than vague recollection.
Pick the review types that fit your company
A full 360-degree process is overkill for many growing companies. Start with what adds signal:
| Review type | Who writes it | When to include it |
|---|---|---|
| Self-review | The employee | Always |
| Manager review | The employee's manager | Always |
| Peer review | Same-level colleagues | When teams collaborate closely |
| Upward review | Direct reports about their manager | When managers need structured feedback |
Peer and upward reviews are optional. Add them once the core self and manager reviews are running smoothly.
Keep the structure consistent every cycle
Employees should never have to relearn the review process. Use the same structure each quarter:
- Accomplishments from the period are surfaced automatically.
- The employee writes a self-review.
- The manager writes their evaluation, with AI feedback on specific strengths and growth areas.
- Reviews are shared and discussed in a one-on-one.
- Leadership calibrates ratings before anything is final.
Consistency across cycles is what lets you compare results over time. Change the structure and last quarter's data stops being comparable.
If you would rather not build the structure at all, performance reviews in WorkSpark ship the phases, rating scale, and competencies already configured.
Set a timeline that keeps momentum
A review cycle that drags on loses credibility. A two-week cycle works well at this size:
- Day 1-2: Launch the cycle and notify everyone.
- Day 3-7: Employees complete self-reviews.
- Day 8-11: Managers complete evaluations and peer reviews land.
- Day 12: Calibration session with leadership.
- Day 13-14: Reviews are shared and discussed.
The deadline is what makes the process work. Without one, reviews drift and the process dies of neglect.
Calibrate before you share results
Uncalibrated reviews create more problems than they solve. One manager gives everyone a 4; another never gives above a 3. When you hand those results to employees, the ratings are meaningless and the process loses trust.
Run a calibration session where managers look at rating distributions across teams before anything is shared. A manager who rates everyone the same, or never gives a top rating, stands out immediately. Fix the outliers before employees see results.
Use best practices that are built in, not rebuilt
The reason growing companies get stuck building review processes is that they treat the structure as something to design. Review forms, rating scales, and competency frameworks can all be pre-built from best practices.
WorkSpark ships this structure out of the box. You choose the review period and which review types to include, then launch. No templates to build, no consultants to hire, and the first cycle can be live in under 10 minutes.
Frequently asked questions
How often should a growing company run reviews?
Most companies at this size run reviews quarterly or twice a year. Quarterly keeps the process tied to recent work; twice a year is enough if the company is still finding its feet with the process.
Should peer reviews be anonymous?
Peer reviews work best when they are structured and tied to the review, not anonymous. Ask peers to comment on specific strengths and growth areas, and let the reviewee see the feedback.
How do I stop managers from giving everyone the same rating?
Calibrate. Show managers the distribution of ratings across the company before results are shared, and discuss outliers. This is the step that turns individual ratings into something consistent.
Do employees see their manager's review before calibration?
No. Reviews are shared after calibration, so the rating an employee sees is the calibrated one, not a first draft that leadership later adjusted.
What happens to reviews from previous periods?
They stay. Previous reviews and the accomplishments behind them remain visible as context, so both the employee and the manager can see how things have changed across cycles. The same applies to the accomplishment tracking that fed those reviews.
