Virtually all companies look to conduct employee performance reviews at some point. People dread this process rather than look forward to it. It takes a lot of time and effort that could otherwise be focused on work. This costs the company money in terms of lost time and unnecessary employee turnover. Because reviews are such a hassle, companies don't like to do them more than once or twice a year and miss out on developing their workforce, constructing a growth-mindset culture, and growing the business.
