First of all, you can briefly introduce your own situation and background, including the nature of work and main tasks. And by the way, you can also mention the background, relevant policies, guiding ideology, and pay attention to concise language.
Second, introduce yourself what you have accomplished during this time. It is best to have specific data and choose those with outstanding achievements, so that your daily work can be brushed aside.
Third, after summing up the work situation, analyze the shortcomings still existing in the work and sum up the experience and lessons.
Finally, write down the future plan, how to correct the mistakes and carry forward the achievements in the next step. It is not enough to reflect on self-analysis in summary. The most important thing is to put forward improvement methods and ideas.
