How can we find the shortcomings in our work?

At work, we are not perfect people with super powers, and we are all more or less flawed and inadequate. How can I quickly find my own shortcomings in my work? The following is my personal opinion. The first is to find out your own shortcomings from the feedback information of the work results. We always have an indicator to do any work. If the task can be successfully completed according to the given standards, and the results can be basically or completely achieved, it shows that our working ability is not bad. If you can't meet the standard at all or the success rate is extremely low, you can quickly detect your own business ability level. The second is to quickly judge your own shortcomings from your own work efficiency. The time interval from task release to completion, to judge the strength of its comprehensive business ability. If you can get into the working state in time and quickly, and adapt to and carry out the work task well, you can complete the task index in the best time range. High efficiency means strong personal ability, and vice versa. In addition, through the work comparison between colleagues, we can quickly find out the shortcomings in our work, thus improving our working ability. If you find that other colleagues around you are very efficient and of high quality, and you have a clear gap with them, you can basically judge your ability level. Of course, it can also be judged from the satisfaction of customer leaders. If you have a strong business ability and a good work attitude, customers will appreciate your tasks more. If leaders attach importance to you and appreciate your ability and attitude, they will give you more or better job opportunities, or be directly promoted by leaders and get more wages. On the other hand, the ability is still insufficient and more efforts are needed.
