After four days and nights of work, the project was finally implemented by users to celebrate. During the implementation of the project, I had some insights. I recorded them a bit and used them as memos.
1. Our project can only be put into implementation when on-site users are not in production. This is a demanding task, especially when there are strict requirements on the project progress. This is because there are very few non-production scenarios for on-site users. In addition, many similar projects need to be implemented once the service is stopped. The maneuver time is quite small. We need efficient and error-free implementation.
2. worried things often happen. I verified this again.
3. Before the on-site implementation, all things should be checked carefully before the on-site implementation, and everything should be confirmed. Otherwise, more time will be delayed at the site.
4. The overall thinking of the project should be grasped and prioritized in emergencies.
5. Assign good hands and clear tasks for each person.
