Charlie and Suzanne have been hard at work on the PPI software project. They recently completed the systems analysis phase. They are now anxiously anticipating the transition to the systems design phase and are discussing the different approaches to systems design. Suzanne comments to Charlie, "You know, I always preferred the structured systems analysis approach over the object-oriented approach. I suppose now you are going to try to persuade me that object-oriented design is better than structured design. So tell me Charlie, why do you prefer object-oriented design?"

• If you were Suzanne, how would you defend the use of the traditional approach to systems design?
• Which systems design approach do you prefer? Justify your answer.
