This book Simulation-Driven Software Engineering: A Behavior-First Discipline for Modern Systems introduces SDSE—a practical approach for modeling, simulating, and validating system behavior before committing to costly implementation decisions. The book explains how teams can maintain a living behavioral model from initial intent through design, development, testing, deployment, and operations—reducing rework, exposing risks earlier, and creating software that behaves as promised.

The BSN Workbench Single-User Edition is available as a free, open-source download under the MIT License.

The repository includes the software package, source files, installation and usage instructions, and the complete README.

This self-paced course explains how to apply Simulation-Driven Software Engineering (SDSE) and use the Behavior Simulation Notation (BSN) Workbench to model, simulate, and validate system behavior before costly implementation decisions are made. This practical course guides you from behavior-first principles through creating and maintaining living behavioral models across the software lifecycle—helping teams reduce rework, manage complexity, strengthen collaboration, and build software that behaves as intended.

The BSN Workbench User Manual provides a complete description of Behavior Simulation Notation (BSN), its modeling constructs, and the BSN Workbench used to apply them. It explains how to represent system components, interfaces, operating conditions, logic, networks, and scenarios; create and simulate living behavioral models; and analyze the results.
