Q 2: Explain why having a standardized system development process is important to an organization? What role does the system analyst plays?

ANS . There is always a right way of doing something, whatever it is that you may be doing. The right way tends to works, and wrong ways either don’t or work very inefficiently. So if you create a system or process by which something is done the right way, this can be used to accomplish whatever it is that your organisation is trying to accomplish (whatever that may be, frying hamburgers, selling houses, arresting criminals, etc.). Without offering any system or process, you would have to ask the members of the organisation to simply improvise everything they do, and that is not going to work. Systems analyst is required in order to identify weaknesses, workarounds and solution on an IT project. They are expert in analysing problems and forming solutions while identifying risks, issues, and impact.

The system analyst is not responsible for coding (although code reviews may be required), but they are responsible for analysing existing systems and identifying suitable solutions.
