Systems & Safety Assurance

Building Justified Confidence in Critical Systems

In safety-critical and highly regulated environments, it's not enough to assume a system will work—you must be able to prove it. At Australia System Assurance Company (ASAC), we provide comprehensive systems and safety assurance services to help you demonstrate that your systems will perform safely, reliably, and as intended throughout their entire lifecycle.

Assurance that Goes Beyond Compliance

Today's projects face increasing pressure to meet stringent safety and reliability standards, while also delivering on broader design, operational, and performance objectives. Success often hinges on having clear, credible evidence that all requirements have been met.

That’s why ASAC integrates structured assurance processes into every phase of project delivery, enabling our clients to reduce uncertainty, manage risks effectively, and build confidence in their systems.

Our Approach: Practical, Proven, and Lifecycle-Focused

With decades of experience in safety-critical industries, ASAC combines practical investigation techniques with both qualitative and quantitative analysis to deliver tailored assurance solutions. Our approach is grounded in how your systems will be used, operated, and maintained in the real world.

We work closely with project teams and stakeholders to:

• Identify, assess, and mitigate risks and hazards early
• Integrate assurance activities into engineering and design programs
• Align safety and reliability objectives with business and regulatory requirements

Supporting Safer, More Reliable Systems

Our services include:

• Development of Safety & Assurance Plans
• Hazard and Risk Assessment Workshops
• Assurance Case Development (including Safety Cases)
• RAMS Modelling – Predicting and demonstrating system Reliability, Availability, Maintainability, and Safety
• Integration of Assurance Requirements into DOORS/DOORS Next
• Evidence Management & Traceability
• Regulatory Review Support and Audit Preparation
• Assurance for advanced signalling systems (e.g. ETCS, CBTC)

We help ensure that risk is reduced to So far as reasonably practicable (SFARP) and that systems are both compliant and operationally effective.

Specialists in Safety-Critical Projects

With deep knowledge of rail systems, signalling technologies, and global safety standards, ASAC brings confidence to complex programs—whether you're implementing ETCS, CBTC, or other advanced control systems.

We support you not only in meeting safety objectives, but in proving—clearly and credibly—that those objectives have been met.
