Output and input design represent something of a “chicken or egg” sequencing problem. Which do you do first? In this edition, we present output design first. Classic system design prefers this approach as something of a system validation test—design outputs and then make sure the inputs are sufficient to produce the outputs. In practice, this sequencing of tasks becomes less important because modern systems analysis techniques sufficiently predefine logical input and output requirements. You and your instructor may safely swap Chapters 15 and 16 if you prefer. |
