In phase 1 of the system development life cycle, which is also known as the planning phase, the following aspects are usually analyzed:
- Outputs: The outputs of a system are the results that it produces. For example, the output of a payroll system might be a list of paychecks.
- Inputs (transactions): The inputs (transactions) to a system are the data that it needs to process in order to produce its outputs. For example, the inputs to a payroll system might be employee timesheets and pay rates.
- Controls: Controls are the mechanisms that are used to ensure the accuracy and reliability of a system. For example, a control in a payroll system might be a check digit that is used to verify the accuracy of employee numbers.
It is important to analyze all of these aspects in order to develop a system that meets the needs of the users.
