Safety analyses
Done early, safety analyses find design weaknesses while they are still cheap to fix. The result is a product that is safer, more reliable and easier to certify.
An investment, not paperwork
Safety analyses show how your system can fail and which safety mechanisms are needed, before late changes become expensive.
- Reveal failure patterns and weak spots in the design
- Choose the right safety mechanisms
- Avoid late redesigns and warranty costs
- Provide the evidence ISO 26262 and your customers ask for
- Align system, hardware and software teams
Analyses we carry out
Failure Mode and Effects Analysis
Looks at each system and hardware component: how it can fail, what the effects are, and how the failure is prevented or detected. Ends in prioritised actions.
Fault Tree Analysis
Works top-down from an undesired event, such as violating a safety goal, to the combinations of faults that can cause it. Shows how well safety mechanisms and redundancy reduce the risk.
Failure Modes, Effects and Diagnostic Analysis
Extends the FMEA for hardware with failure rates and diagnostic coverage, and calculates the single-point and latent fault metrics needed for the target ASIL.
Hazard and Operability Study
A moderated workshop that uses guide words to find functional deviations and the hazards they create. Most useful early, in the concept phase.
Dependent Failure Analysis
Required by ISO 26262. Shows independence and freedom from interference between elements, covering common cause and cascading failures such as shared power, clocks or computing resources.
