Dear Kumar,
Let me tell you one thing: objects vary from place to place or environment to environment, but that doesn't mean you can change the whole concept. What I'm trying to establish here is that we, South Asian people, often "look good, do nothing, and pin others," especially when we have power. However, we don't see Performance Appraisal as a system for determining how well an individual employee has performed during a period of time.
Now here's the problem: if someone is performing with their heart and soul without any prior record, then most likely, he or she will get rewarded based on the whim of their boss. But if every task is clearly outlined and recorded for the employee to follow, the superior can't easily manipulate the subordinate, as the employee has a documented record of what was asked and what was done according to the manager's requests.
In our case, working in a large conglomerate, managers hold significant power and can easily manipulate their subordinates, leaving the impression of a slay-monster. To overcome this issue, we have implemented a known KPI system in the appraisal process for assessing subordinates. KPIs carry greater weight compared to core/professional competencies. Simultaneously, we have granted subordinates various rights to provide evidence that can genuinely support their evaluation. They can also challenge any treatment they perceive as unfair by presenting their KPI results set at the beginning of the year.
Does this make sense now? However, all these aspects are dependent on the environment in which you work. If you find yourself among goofies, then perhaps it's time to explore other opportunities.
Cheerio,
AdaM
