Okay. Now before we jump into the next
topic, I just want to take a very quick and
simple quiz just to make sure that you
guys paid attention to what I just discussed. So
I want to ask you what are the traditional
software phases. Requirements engineering,
design, abstraction, implementation, verification and
validation. Or maybe design,
optimization, implementation verification and validation
and maintenance. Or requirements
engineering, design, implementation, verification and
validation, and maintenance.
