b. Fredrick Brooks correct answers In the paper "Software Requiements Engineering: What,
Why, Who, When and How", this quote about the requirements:
"The hardest part of building a software system is deciding precisely what to build. No other part
of the conceptual work is as difficult as establishing the detailed technical requirements,
including all of the interfaces to people, to machines, and to other software systems. No other
part of the work so cripples the resulting system if done wrong. Neither part is more difficult to
rectify later"

True correct answers In the paper "Software Requirements Engineering: What, Why, Who,
When and How", this quote about the requirements:
" Requirements development is an iterative process. One should not expect to go through the
steps in a one-shot, linear fashion. For example, the requirements analysts may talk to a user,
then analyze what the user had to say. They may go back to that user for clarification and then
document what they understand as that part of the requirements. They may then go on to talk to
another user, or hold a joint requirements workshop with several user representatives. Their
