Thanks for your perspective Robert.

I don't see usabilty itself as an NF requirement. The NF requirement is to<br class="">
minimise data redundancy. Decreased redundancy then increases the usability<br class="">
of the database.<br class="">

Subject: [Year 12 SofDev] usability - NF requirement or constraint or<br class="">
both???<br class="">
<br class="">
<br class="">
Hi all, <br class="">
<br class="">
I've attached a graphic organizer that will hopefully get my kids thinking<br class="">
more carefully during their analysis of a problem, need or opportunity. Do<br class="">
others use something similar? I'd love to hear your feedback.<br class="">
<br class="">
However, in doing so I realized that usability is listed as both a<br class="">
non-functional requirement AND a constraint. My brain had been thinking that<br class="">
a social constraint such the users' level of expertise or some other<br class="">
"audience characteristic" would impose a non-functional requirement in<br class="">
relation to the usability of a solution.<br class="">
<br class="">
Could someone please explain the difference between usability as a<br class="">
constraint and as a NF requirement? I know that I WILL be asked the same<br class="">
question :-/<br class="">
<br class="">
Thank you!<br class="">
<br class="">
<br class="">
