A technique is described for software specification and verification of concurrent, distributed systems. The complete specification of a program is given in terms of a hierarchical structure of module specifications. Module external specifications are abstract; module internal specifications are descriptions of internal implementations, either in terms of submodules or actual code. The verification that an implementation satisfies its specification is language independent for the former and language dependent for the latter. Distinguishing the liveness properites provided by a module and the liveness properties required by a module (from its comodules) allows the specification and verification of a given module to be independent from the specification and verification of its comodules.

We propose a software life cycle which consists of two phases: rapid prototyping and automatic program generation. Software reusability holds the biggest leverage for both phases. This paper outlines the requirements for supporting this two-phase life-cycle using a software-base as an advanced software management system.
