How do we fill the gap between each steps

I am curious about how could we fill the gaps among those steps

  • collect business requirements
  • use case analysis and diagram
  • class analysis and diagram
  • activity analysis and diagram

From the Libray System Business requirements, we cannot event found any words like renew but it did show in the use case diagram. In the process set in between, is there any steps we missed? or in the process we need to ask the interviewer to clear these requirements?

Hi @James9
System requirements provided in this lesson are basic requirements. The interviewer can further add or mold requirements during the interview.
