Once that process is complete, you launch the program for public or private use and provide support and upgrades to the user. You should have extensive knowledge and experience working with software development, and if you are working in IT for a company, you should be able to troubleshoot their current mainframe. Teaching others about what you have developed and making sure they understand how to use it are also your responsibility.
