requirement or constraint or both???<BR></FONT><BR></DIV>
<DIV></DIV>
<DIV style="WORD-WRAP: break-word">Hi all,
<DIV><BR></DIV>
<DIV>I’ve attached a graphic organizer that will hopefully get my kids thinking
more carefully during their analysis of a problem, need or opportunity. Do
others use something similar? I’d love to hear your feedback.</DIV>
<DIV><BR></DIV>
<DIV>However, in doing so I realized that usability is listed as both a
non-functional requirement AND a constraint. My brain had been thinking that a
social constraint such the users’ level of expertise or some other "audience
characteristic" would impose a non-functional requirement in relation to the
usability of a solution.</DIV>
<DIV><BR></DIV>
<DIV>Could someone please explain the difference between usability as a
constraint and as a NF requirement? I know that I WILL be asked the same
question :-/</DIV>
<DIV><BR></DIV>
<DIV>Thank you!</DIV></DIV>
