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

[Young, Katherine A]

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,
