"I implement source control on all my software development projects. For example, on a recent project in which we were asked to develop a healthcare enrollment and management system for the company, we used the Agile methodology to create the application. At each step of the process, my team documented the work performed on the software and assigned it a version number before moving on to the next development phase. This came in handy when we encountered a SQL error which we discovered was based on the most recent code implemented. We were able to roll back the software to a previous version and implement the SQL commands correctly."
