Vienna Development Method

The Vienna Development Method (VDM) is one of the longest-established formal methods for the development of computer-based systems. Originating in work done at the IBM Laboratory Vienna in the 1970s, it has grown to include a group of techniques and tools based on a formal specification language—the VDM Specification Language (VDM-SL). It has an extended form, VDM++, which supports the modeling of object-oriented and concurrent systems. Support for VDM includes commercial and academic tools for analyzing models, including support for testing and proving properties of models and generating program code from validated VDM models. There is a history of industrial usage of VDM and its tools and a growing body of research in the formalism has led to notable contributions to the engineering of critical systems, compilers, concurrent systems and in logic for computer science.«Towards the end of 1972 the Vienna group again turned their attention to the problem of systematically developing a compiler from a language definition. The overall approach adopted has been termed the 'Vienna Development Method'... The meta-language actually adopted ('Meta-IV') is used to define major portions of PL/1 (as given in ECMA 74 - interestingly a 'formal standards document written as an abstract interpreter') in BEKIČ 74.» The Vienna Development Method (VDM) is one of the longest-established formal methods for the development of computer-based systems.
