<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 &quot;audience characteristic&quot; 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>
