RAMS & Certification Support

Systems and software are more functional and easier to use than ever before. However, ‘behind the scenes’ complexity continues to build, which can introduce new challenges and increase the risk of failure. With the growth of automation, manufacturers and developers are increasingly liable for the safety and performance of their systems, software, products and services. The importance of getting things right and demonstrating they are safe is more crucial than ever before.

Assuring safety and compliance with industry mandated standards can be a difficult and costly task if not handled properly. CRITICAL Software’s expertise in safety and certification compliance for embedded systems helps to ensure requirements are met in the most efficient and stress-free way possible. Our expertise spans across standards such as ARP-4754, ARP-4761, DO-178B/C, DO-254, IEC 61508, EN 50126/8/9, ISO 26262, ESA ECSS series and more.

Our range of RAMS and certification support services include:

  • Safety & certification requirements gap analysis assessment
  • Certification support (including planning, V&V, configuration management, requirements, design)
  • Reliability assessments of electronic systems (MIL-HDBK-217, RIAC-217 Plus)
  • Safety assessments, both independent or integrated within project teams
  • System reliability analysis (Weibull, FTA, FMECA, RBD)
  • Training on safety processes and certification standards

We are able to determine all safety and certification requirements relevant to a given development project, effectively planning and designing systems with certification compliance in mind, executing safety assessments in an efficient way and interacting with certification authorities where necessary. With vast experience in electronics, embedded software systems, FPGA/ASIC design and enterprise applications, our services are backed by a delivery unit that is rated at Capability Maturity Model Integration (CMMI)® Level 5, the highest obtainable level, and a roster of quality certifications that include ISO 9001:2008, NATO AQAP 2210 and 2110 and AS 9100.

RAMS and Certification Support for Aerospace

The aerospace industry has stringent certification requirements like no other. These requirements form an extended ecosystem that spans across subsystems, equipment and software deployed on aircraft and critical CNS/ATM infrastructure. Understanding the full range of applicable certification requirements and their implications is a key factor in the success of aerospace projects. Equally important is how best to address these requirements in real-life projects - effectiveness in certification and efficiency in business are both key to success.

Through its highly-skilled engineering team and a world-class partnership network, CRITICAL Software supports its clients in delivering aerospace projects effectively, efficiently and in a stress-free way. Our RAMS & Certification Support services for aerospace include:

  • Project gap analysis: identification of gaps with respect to the certification baseline and determination of the best way to overcome them, given specific project and customer needs.
  • Certification baseline definition: identification of the full set of guidance and guidelines, normative provisions and relevant agency documentation, including TSO/ETSO, circulars, CAST papers, memoranda and other items that are applicable to a specific project.
  • Project planning & SOI/LOI support: definition of DO-178B/C and DO-254 plans, fully-tailored to specific needs to maximise project compliance and efficiency. This can also be combined to support SOI/LOI preparation.
  • RAMS analysis: reliability prediction of electronic equipment (MIL-HDBK217, RIAC 217 Plus), safety assessment of airborne embedded systems and CNS/ATM C&C infrastructure (ARP 4754, ARP 4761, IEC 61508).
  • Training: covering the core industry standards for software and airborne electronic hardware: DO-178B, DO-178C, DO-278A and DO-254. Course content can be customised to address specific client needs.

RAMS & Certification Support for Automotive

Advances in electronic control units (ECUs) were key to many of the efficiency and safety improvements we now enjoy when using the automobile. These advances turned the car from a mechanical machine to an immensely complex cyber-physical system, changing the driver's role in subtle yet impressive ways. In the future, the driver may be removed from his position behind the wheel altogether.

Whatever the future holds for drivers, the increasing complexity of ECUs and the software they host, and the relentless market pressure to shrink development cycles, poses a formidable challenge to designers, developers and functional-safety practitioners across the entire supply chain. In this context, ISO 26262 is a proposed solution to these new safety challenges, but comes with challenges of its own.

CRITICAL Software has deep-rooted experience in functional-safety and critical embedded systems across several industry sectors. Our broad experience in safety and certification enables us to help our customers to achieve effective functional-safety, tackling and applying ISO 26262 and more, in a business efficient way. Our RAMS & Certification Support services for the automotive sector include:

  • Training & coaching: on ISO 26262 and on how to introduce formal safety management and product assurance processes in an effective and efficient way.
  • Safety analysis: management of functional safety across the lifecycle, spanning through system, hardware, software or any combination of these. This includes criticality determination, allocation of ASIL to functions, assurance of partitioning integrity (for mixed-criticality systems), elaboration of the safety case, and more.
  • Project planning & support: definition of the project plans required by ISO 26262, enabling effective compliance and project efficiency. This may also include project specific support to implement safety across the lifecycle.
  • Safety & quality audits: performed at either a project or organisational level to uncover existing gaps and produce recommendations on how best to overcome them.

RAMS & Certification Support for Railway

Railway is the oldest transportation system in the world and the first to bring to light the need for functional safety. The railway industry can be divided into two main branches: rolling stock (locomotive, light rail, suburban, intercity and high-speed), and signalling systems (including ERTMS and CBTC). CRITICAL Software’s functional-safety experts cover both of these branches.

Rail is one of the most efficient mass transportation systems in the world. A rail revival is spreading across several countries and geographical regions. New standards are being implemented (e.g. ERTMS) and legacy systems are being replaced. The market landscape offers opportunities but also strong competition among global railway suppliers. CRITICAL's role in this landscape is to contribute to the systematic growth of rail safety by helping its customers achieve safety requirements in a business-efficient way.

Our RAMS & Certification Support services for railway include:

  • Project gap analysis: identification of gaps with respect to the safety requirements, namely those in EN 50126, and determination of the best way to overcome them, given specific project and client needs.
  • Safety management & safety case preparation: management of functional safety across the lifecycle, for both rolling stock and signalling systems, including the elaboration and management of the safety case.
  • Independent Safety Assessment (ISA): compilation and review of all project safety artefacts as to assess compliance with applicable regulation (both international standards and national regulation).
  • Training on functional safety: addressing the provisions of EN 50126, EN 50128 and EN 50129, either focusing on global normative aspects, project-specific needs or both.
