It depends on the content of the report and the preference of the leader. Generally speaking, the report should be simple and clear, but it should also contain enough details so that leaders can understand the progress and achievements of the project and any problems that need to be solved. Here are some guiding principles:

1. Understand the preferences of leaders: Before making a report, try to understand the preferences of leaders as much as possible. Some leaders may prefer detailed data and analysis, while others may just need a short summary.

2. Concise and clear: The report should be concise and to the point, and avoid using complicated technical terms or terms. Use simple language and charts to help leaders understand your report better.

3. Include key information: The report should include key information, such as the progress, completion and achievements of the project, as well as any potential risks or challenges. This information should be detailed enough for the leaders to understand the situation, but it should not be excessive.

4. Suggest solutions: When problems are found, propose solutions. Your leader may appreciate your initiative and suggestions, rather than just pointing out problems.

To sum up, the best way is to try to understand the needs and preferences of leaders and provide concise information with key details in the report.
