Application of standards for critical software and systems development

Systerel follows rigorous development processes drawn from its experience with safety-critical systems, fully compliant with applicable standards and tailored to client constraints.

The most critical systems are typically subject to certification authorities, which verify that all standard-defined requirements have been met before issuing certification.

The use of formal methods is strongly encouraged—and in some cases, required—by certain standards.
