In the past two years, we've taken on several software operation and maintenance projects. The clients who came to us for operation and maintenance either had their original companies go bankrupt or were dissatisfied with the poor service of their previous providers and wanted to switch to a better - serviced company. For example, there was a sales management software project. The client chose an individual developer for the sake of cost - effectiveness. Although the project was launched as normal, many unexpected problems cropped up during its operation. When it came to having the developer handle the operation and maintenance, an issue arose. Since the developer was also working in another company, if a problem was discovered during the client's working hours, the developer could only deal with it after work. After the developer fixed the problem and gave feedback, the client had to wait until the next working day to let the sales team test and verify. If the problem wasn't fully resolved, the feedback process had to be repeated, along with waiting for the developer's availability. After such back - and - forth for several times, the client couldn't tolerate the quality of this maintenance service and thus turned to us to take over the project. Fortunately, the project had the complete source code, so it was handed over to us for operation and maintenance. There was also a company website project. The client in Beijing, aiming to save money, hired an out - of - town team. The project was successfully launched, but within two years, the original company couldn't be reached. Luckily, the entire source code had been delivered to the client. Our technicians checked the source code and confirmed it was workable, so we took over the operation and maintenance. In fact, the two cases above are relatively favorable. Because we had the project source code, and the source code versions and development technologies happened to be within the scope of our technicians' knowledge, enabling us to carry out the operation and maintenance. In fact, there are many projects that come to us for operation and maintenance which were built using source code randomly bought online. Those are just running source codes without the engineering source code, making them unmodifiable. As a result, many of these projects have to be redone. So, as we can see, once a software project is in use, it requires a team for long - term operation and maintenance. Many people think that once a software is developed, there's little left to do in terms of operation and maintenance. In fact, as long as the software project is still in use, it may involve performance optimization due to large amounts of data, adjustment work for changes in plugins and components, security work to prevent hacking and theft, and ensuring data security, among other things. There's still a lot of work to be done. Moreover, the stability of a project is closely related to the technical capabilities and response speed of the maintenance team. Normally, when we do dedicated project operation and maintenance, there are indeed many tasks to handle, such as system performance monitoring, fault troubleshooting, security management, data backup and recovery, performance optimization, software updates, server configuration, log analysis, and so on.
