Why Start Your Functional Safety Journey Here

This guide describes an example process that incorporates well-proven quality and software engineering methods evolved over decades of real-world experience at exida.

The core philosophy of our approach is the verification of quality in every single step of the development process. By embedding rigorous quality checks early and often, you can ensure your design:

  • Achieves Higher Quality: Build robust, reliable safety systems from the ground up.
  • Minimizes Design Defects: Catch and correct errors before they become costly failures.
  • Provides Better Economic Return: Reduce redesign time, shorten compliance cycles, and lower lifecycle costs.
