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

[Laurie Savage]

Thanks for sharing that, it's very nicely set out and reinforces all these
criteria well.

For my 2-bob's worth I would regard usability as a constraint, it seems
implicity functional that something be usable but the degree to which it is
is defined by the skills and experience of your users. In the same way your
printing (functional requirement) is constrained by the specifications of
your printer.

Others might disagree.
