Many HR professionals and even managers agree that traditional performance reviews are not effective at all. Traditional performance reviews foster animosity and reduce employee morale, making them less loyal to the company as they perceive that the company is not concerned with employee development. In fact, this obsession with rewarding employees based on the amount of work rather than the quality of work. Additionally, often only one manager is involved in giving performance reviews and appraisals and he/she has no idea how well the employee is doing and often let bias creep in.
