B formal method

The B formal method is a rigorous approach used in software and system development to specify, design, and verify complex systems. It employs mathematical models to precisely describe the desired behavior and structure, enabling early detection of errors and inconsistencies. By specifying systems formally, B helps ensure correctness, reliability, and safety, especially in critical applications like aviation or banking. Think of it as creating a detailed, mathematical blueprint that guides the development process and confirms that the final system matches its specifications before implementation begins.
