Now before we move to the last part of the lesson, let's
have a quick quiz on software process models to make sure that
we are all on the same page. So I am going to
ask you two questions. The first question is which of the following models
is most suitable to develop a software control system? And when you
think about the software control system, you can think about for example
the control system for the software in an airplane. Would you rather
use a pure waterfall model? Test
driven development? Or an evolutionary prototyping approach?
