[Year 12 SofDev] usability - NF requirement or constraint or both???

[Robert Hind]

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

Subject: [Year 12 SofDev] usability - NF requirement or constraint or
both???


Hi all, 

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.

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.

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 :-/

Thank you!




Regards,
