The '''VDM''' (Vienna Development Method) is one of the earliest formal methods for software development, developed at IBM's Vienna Laboratory in the 1970s by researchers including Cliff Jones and Dines Bjørner. It provides a model-oriented specification language — '''VDM-SL''' (VDM Specification Language) — based on discrete mathematics, set theory, and predicate logic, allowing developers to specify system behavior through abstract data types and operations defined by preconditions and postconditions. VDM introduced the concept of data reification (replacing abstract data types with concrete representations) and operation decomposition (breaking high-level operations into implementable steps), both justified by proof obligations that ensure correctness is preserved through refinement. Unlike the [[B method]] and [[Z notation]], which emphasize state-based invariants, VDM is more explicitly oriented toward the stepwise development of implementations from specifications. VDM has been used in the specification of programming language semantics, compiler construction, and industrial control systems. The method's influence persists in modern specification languages and in the theoretical foundations of software refinement, even if its direct industrial use has declined relative to newer tools. The '''[[RAISE]]''' method (Rigorous Approach to Industrial Software Engineering) was a later European project that attempted to unify VDM, Z, and other formal approaches into a single industrial-strength framework.
