Safety & Mission-Critical V&V

Verification for systems where the cost of being wrong is not measured in downtime.

Where Independence Stops Being Optional

At the higher assurance levels the standards stop suggesting independence and start requiring it. DO-178C expects verification independence for the objectives that carry the most weight; ISO 26262 asks for it by ASIL; EN 50716 by SIL. The question is rarely whether someone reviews the work. It is whether the reviewer is independent in a way the authority will accept.

We have no delivery arm, no products inside your supply chain and no revenue that depends on your program being approved. That is the difference between a second opinion and independent verification.

What the Work Actually Is

Four activities, run on their own or as a continuous engagement alongside the program.

+Requirements and design review

Every requirement traced to its source and to the test that demonstrates it. Ambiguity found at requirement level costs a fraction of what the same ambiguity costs at integration.

+Code and structural coverage analysis

Verification against the objectives your assurance level carries, including the structural coverage your tests never reach and the justification for whatever remains uncovered.

+Independent testing

Tests designed and run by people outside the delivery organization, against the requirement as written rather than as remembered.

+Certification evidence

Artifacts assembled, traced and defended in the form the certification or qualification authority will ask for, not in the form your tooling happens to produce.

The Standards This Work Is Measured Against
We verify against the standard that applies to your domain, at the assurance level the function actually carries.
+ Airborne systems

DO-178C / ED-12C for software, DO-254 / ED-80 for complex electronic hardware, and DO-330 for the tools the process depends on.

+ Aircraft and system level

ARP4754B for development assurance and ARP4761A for safety assessment — where most of the argument is actually decided.

+ Road vehicles

ISO 26262 at the ASIL the function carries, with ISO 21448 where the hazard is the intended behavior rather than a fault.

+ Railway

EN 50716 for software and EN 50129 for safety-related electronic systems, read together with CLC/TS 50701 for cybersecurity.

+ Medical devices

IEC 62304 for the software lifecycle and ISO 14971 for the risk controls that lifecycle has to implement.

+ Security inside safety

DO-326A / ED-202A and EASA Part-IS in aviation, ISO/SAE 21434 in automotive, IEC 62443 in industrial control.

Where This Applies

Four of the six sectors we serve, where independent verification is either a regulatory requirement or the only way to know.

What the Team Has Worked On

Described by what the systems had to do and at what level, rather than by client name.

Airborne software and hardware

Systems taken from requirements through to certification evidence at the higher design assurance levels, with the hardware verified alongside the software that runs on it.

Rail signalling and onboard software

Safety-related software and electronic systems at the integrity levels where an assessor is part of the process.

Medical device software

Device software in classes where a notified body reads the technical file rather than taking it on trust.

Government acceptance

Defense and public programs where the acceptance decision sat with an authority rather than with the supplier.

The authority decides on evidence
not on effort.
Tell us the platform, the assurance level and who has to accept it. We will tell you where the argument is thin.
