Software engineering goes through several phases. These phases are: 1. Identify the problem. 2. Develop a plan of how to solve this problem. 3. Write the code per this plan. 4. Test if that code works. 5. Improve the solution. It is the stage where software bugs are fixed and enhancements are made to improve this software solution. YouTube video
