[comp.software-eng] Z, VDM and non-functional requirements

krees@axion.bt.co.uk (Kearton Rees) (06/19/91)

Does any one have (or know of) information on how
Z and VDM handle non-functional requirements?

(By non-functional requirements I mean attributes like ease of use,
performance, ease of maintenance, availability, security, reliability etc.)
