Documentation

When we make changes to a system, it is crucial to document those changes so that we have a record of what was done. This documentation helps with system maintenance and allows future programmers to understand the changes that were made.

Additionally, we have something called an audit trail, which is a set of information that keeps track of who made the changes and what changes were made. This audit trail is created by the system itself and is important for accountability purposes. It helps us identify who is responsible for the changes and provides a record of the changes made.

It's also important to note that when we make changes, we need to test the system to ensure that the changes do not cause any problems or create new issues. After testing, we present the changes to a change control board, which reviews the changes and determines if they are legitimate and beneficial for the system.

Once the changes are approved, we move on to implementation, which involves putting the changes into the production environment. It's important to have a process in place for every change, including approval, documentation, and the creation of an audit trail. This ensures that we have a record of the changes and can easily roll back to a previous version if needed.

Overall, documentation and audit trails are essential for system maintenance, accountability, and ensuring that changes are properly implemented.
