Specification Driven Development

This post argues that Application Management should use a design model, a representation describing aspects of a system that is not easily, or sufficiently, captured through implementation, in managing on-line openness in IT. The post introduces development architecture and specification driven process resulting to better systems, ease in system development management, ease in system test management, and generally allowing better control of IT development, and explains, how to keep design model and implementation in sync, and how scaling up of the approach is achieved.

Demonstrate Sbuilder Translation Results

This blog entry uses a very contrived example to demonstrate, how to include manually crafted TLA+ snippets into a formal model created by SBuilder. The main purpose is to 1) show, how to bind TLA code with Solidity interfaces, 2) understand TLA -files generated in Sbuilder translation, and 3) explain, how Sbuilder “possibility” operator relates to model checking formal model correctness. A more realistic example of using manual TLA+ to specify is given in another post.
