Proof Driven Development

A new workflow for software development (proof-driven development) is presented. An extension of test-driven development, the new workflow utilizes the paradigm of dependently typed programming. The differences in design, complexity and provability of software are discussed, based on the technique used to create the system. Furthermore, the difference in what properties can be expressed in a proof-driven development workflow versus a traditional test-driven development workflow or using test-last development.
