Abstract
This paper discusses the reuse and adaptation of specifications in Z and object oriented Z, and provides techniques based on a calculus of refinements and on measures of specification design quality, which attempt to address these issues. This calculus will form the basis of a proposal to extend the logic W for standard Z [40] to a reasoning formalism suitable for proving relationships between specifications at a global level. Comparisons with the facilities offered by object oriented specification languages, and with the B abstract machine notation are given. Examples from industrial case studies of the applications of these techniques are also provided.
