For most managers and employees, year-end performance reviews are like going to the dentist\u2014if your dentist also hated the experience of looking inside people\u2019s mouths.A CEB study on the subject confirmed that nearly everyone is unhappy with our current method of evaluating performance. In it, 95% of managers said they were dissatisfied with their performance management systems, and 90% of HR heads reported that the system didn\u2019t yield accurate information.Despite this dissatisfaction, yearly performance reviews are still the norm in most American workplaces (with some notable exceptions). The argument in their favor is that a flawed system is better than no system at all, and organizations need some method of keeping track of how team members are doing so they can reward good behaviors and correct bad ones.The problem is that we place so much importance on annual reviews that they become sources of intense anxiety for employees, who often feel like they have no idea what their manager is about to tell them. Meanwhile, they\u2019re nearly as stressful for managers, who feel intense pressure to appease both their team members and their own superiors.It doesn\u2019t have to be this way. As a manager, you can set both yourself and your employees up for success in year-end reviews. And it starts by taking advantage of the regular one-on-one meetings you should already be having.Prep for Year-End Reviews With One-on-OnesThere\u2019s a fundamental, structural problem with the year-end review: Employees get a sudden spike in manager feedback followed by months of relative quiet. In the time between reviews, employees have no idea how their work is being perceived, and no chance to explain things from their perspective.Some businesses have tried to tweak the structure by switching from year-end reviews to six-month or quarterly reviews, but that leaves us with the same problem, in which rich feedback remains the exception rather than the rule. The solution is to implement regular one-on-ones in which employees and managers check in and realign about performance.CEB\u2019s research illustrates the difference between the two models with a helpful graph:This doesn\u2019t mean that every one-on-one should feel like a year-end review, quite the opposite. One-on-ones aren\u2019t a chance for employers to pass judgment on an employee, but to gain context about what\u2019s going right and wrong, and give employees the opportunity to work through issues.If you\u2019re using one-on-ones right, they can take the pressure off year-end reviews, because you\u2019ve already established a relationship built on collaborative, constructive feedback. Below, we\u2019ll get into the specifics of how to do that.Document Performance All Year RoundIf you sit down to write an employee\u2019s annual review and all you can come up with is a vague impression about how they did last year, you\u2019re dead in the water. You need to be able to back up everything you say, positive and negative, with specific examples from throughout the year. To do that, you need to document each individual\u2019s performance and be able to easily access it to write the overarching narrative of their year at work.More than any other resource, your notes from one-on-one meetings are the best way to ensure your review accurately reflects your employee\u2019s performance. Raw numeric data, without the benefit of context, will never give you the whole picture, and can lead you to make the kind of reviews that shock your team.As a simple example, a spreadsheet might show that one employee turned in work on time much more consistently than their peer. But it would fail to note that the on-time employee\u2019s work was often slipshod, or that the employee who ran late was struggling with more difficult assignments or personal challenges. Your one-on-ones, on the other hand, give you the chance to find and make a note of that crucial context.Uptick is designed so that if managers ask the right questions and take helpful notes, they can populate year-end reviews with content from a year\u2019s worth of one-on-ones.Just as crucially, employees should also be documenting what you\u2019ve discussed in meetings, including their successes, their trouble spots, and their goals. They can use this data to fill out their self-review and make a case for why they deserve that promotion or that raise. And if there\u2019s a point of contention between you and an employee, you can both refer back to the record.One-on-one documentation is your ally when you need to make recommendations about a team member\u2019s path forward. If you have to ask HR that someone be fired, you can show them a record of commitments that this person made and then failed to keep. But even more importantly, these notes will back you up when you give glowing reviews.One-on-one notes are your best defense against feeling like a traffic cop who has to hit a negative feedback quota.If all goes right, you\u2019ll be able to prove that you have an exemplary team full of people who are growing and succeeding in their roles.Clarify Expectations to Avoid Year-End Review SurprisesPerhaps the most dread-inducing part of annual performance reviews is the element of surprise. Employees can walk in expecting to hear glowing praise, and be blindsided by criticism. Writer Katie Heaney accurately described this sensation from an employee\u2019s perspective: \u201c…you\u2019ll be called into a meeting with your supervisor, who will tell you why you\u2019re a worse employee than you thought, and possibly present you with a piece of paper summarizing the reasons why.\u201dLikewise, managers often assume that their reports are ready to hear tough feedback, and are unprepared when their team members walk away hurt and angry. Those hurt feelings have real consequences: A 2015 survey by HR company TriNet found that 28% of Millennials looked for a new job after a poor performance review (and 15% cried). The survey also found that 74% of Millennials feel \u201cin the dark\u201d about how managers and colleagues perceive their performance, and 40% thought the process would be improved by more specific feedback.The cure for annual review shock is for managers to communicate specific expectations on an ongoing basis and regularly check in to ensure employees are meeting them. Here\u2019s what that looks like in practice:Set incremental benchmarks in every one-on-one to ensure your team members know what they\u2019re supposed to be doing. These should include both short-term priorities and long-term developmental goals, but you should regularly check on the progress of each. That way, an employee doesn\u2019t have to wait until review time to hear they\u2019ve gotten off-track or they aren\u2019t meeting expectations. Most importantly, it gives them the chance to fix the problem before it hurts their career.Provide detailed roadmaps for roles during onboarding and whenever an employee steps into a new position. In these, delineate specifically what an employee is expected to know and do by month one, three, six, etc. Not only will this help your team members get a sense of how to structure their time and effort, but it\u2019ll also keep you honest by not expecting an employee to take on more than their role requires.Provide both \u201cfeedback\u201d and \u201cfeed-forward\u201d on completed and upcoming projects. Take time with your team member to reflect on what went right and wrong with the work they\u2019ve completed, and collaboratively set goals for the work to come.A New Beginning for Year-End ReviewsYear-end reviews have such a bad reputation because the review process feels opaque and arbitrary to employees. That\u2019s a serious problem for businesses\u2014if a team member thinks that what they do doesn\u2019t matter, they don\u2019t have much of an incentive to try their best. Maybe even sadder, if a team member feels like their manager isn\u2019t on their side in reviews, it can destroy trust, communication, and the entire working relationship.The alternative to this is a system where managers and team members walk into year-end reviews knowing there will be no surprises. Each party can feel confident they\u2019re working from the same set of expectations, informed by context and collaboration. As a manager, the tools to make this change are already at your disposal. When you put them to work effectively, you\u2019ll find yourself with a lot more positive things to say during next year\u2019s reviews.
