Answer 2

System Analysis and Design is the phase of Project Management wherein the existing system is analysed and the design of the new intended system is developed. It is more of understanding the situation rather than solving the current issues and problems at hand. The Project management includes planning, executing, monitoring, controlling and closing the project at hand.
