A performance review is a structured, scheduled evaluation of an employee's work performance against agreed objectives and competencies. Its purpose is to recognize achievement, provide honest feedback on areas for improvement, align on goals for the next period, and agree on a development plan. When done well, it is the most important conversation a manager has with a team member each year.
Recency bias · evaluating only the last month or two rather than the full review period. Managers also commonly confuse activity with output (how busy someone was versus what they achieved), avoid giving specific critical feedback to spare feelings, and write generic comments that could apply to anyone. The most damaging mistake is delivering feedback that surprises the employee. If something was worth saying in a year-end review, it was worth saying when it happened. Reviews should confirm what has been communicated throughout the year.
In most cases, yes. A self-assessment before the manager assessment serves three purposes: it gives the employee agency in the process, it surfaces how the employee perceives their own performance (which may reveal important gaps or over-confidence), and it reduces the amount of information the manager needs to gather themselves. Sharing the manager's assessment before the self-assessment is complete undermines the exercise · the employee adjusts to match.
Both approaches have merit. Numerical ratings (1 to 5) enable cross-team comparison and compensation benchmarking. Categorical ratings (Exceeds / Meets / Below expectations) are simpler to explain and discuss. The most important factor is calibration across managers · a 4/5 from one manager should mean the same as a 4/5 from another. Without calibration sessions, rating scales lose much of their meaning. Whatever system you use, anchor each rating level to specific observable behaviors.
Plan around 60 minutes for an annual review. 90 minutes is better for a team member with a complex year or significant development needs. A rushed conversation can signal to the employee that the review is a formality, not a genuine investment in their development. The conversation itself matters as much as the written document · a review that is completed online and never discussed can leave the employee feeling unheard.
Many organizations hold the pay conversation separately, so the review stays focused on performance and development. A classic field study at a large company found that goal setting improved performance more than criticism did, that coaching worked better as a day-to-day practice than as a once-a-year event, and that appraisals serving different purposes worked better as separate discussions. A pay figure tends to take over any conversation it enters. A common pattern is to hold the review first, then confirm any pay change in a short meeting a few weeks later, with the link to the review stated plainly. Source: Herbert H.
