In addition to an understanding of processes, tests and software development, our tasks include functional safety, in other words an understanding of norms and standards and compliance therewith.
Industry employs the international generic IEC 61508 standard. This is regarded as the Basic Safety Publication. Within railway technology, the CENELEC standard, DIN EN 50128, on functional safety in the field of software development is mandatory. Since 2012, another key focus for seneos has been within the area of functional safety in the automotive sector and the relevant ISO 26262 standard.
Through its strategy, seneos promotes the effective reduction of product risks to a minimum in order to improve product liability taking into account overall expenditure. In this respect, seneos provides responsible advice and support within automotive client projects for German OEMs and international suppliers.
Services within the field of functional safety in accordance with ISO 26262: The ISO 26262 standard has been setting the rules for functional safety within the automotive sector since 2011. That does not mean it is music to developers’ ears however. A pragmatic approach to ISO 26262 can change that. The aim here should be to generate the greatest possible added value for the development of product through reasonable expenditure. Thus the obligation becomes a virtue and confidence in the safety of in-house products grows.
Services within the field of functional safety in accordance with ISO 26262:
The ISO 26262 spans the entire development V model: every activity within the V model is linked to a functional safety task. A clearly structured functional safety management strategy is required to maintain an overview of all activities. That is the only way of complying with the key point required by the standard, seamlessly planned development from the outset through to safety certification.
The seneos Functional Safety Manager provides expertise in both areas throughout the V model when it comes to interweaving management and development. We believe that our management strategy specially adapted to the customer enables optimal collaboration. Our management guidelines are customised to the customer’s project and development structures in order to offer the utmost flexibility and efficiency.
Our functional safety activities include:
seneos uses the medini analyze tool from IKV (www.ikv.de) in its functional safety projects. From drafting to review of the hazards and risk analysis, the workflow agreed upon between developer and reviewer is implemented within medini analyze. Furthermore, safety concepts integrated within the tool can be systematically broken down, for example, to component level in hardware or to model level in software. The mapping of analysis methods within the tool itself makes the individual requirements clearly traceable. Using this tool within an ISO 26262-compliant development project from the outset reveals a common theme which is evident through the seamless composition of the security certificate and contributes significantly to its transparency. The system has already paid off when used in large-scale projects with vehicle manufacturers due to a clearer overview of functional safety across all projects.
How many software tools do you use in your day-to-day work? How many of them significantly influence the development process? How many of those tools work unequivocally correctly? Have you ever even asked these questions? seneos helps you answer these and many other questions within the context of ISO 26262-compliant tool management. To achieve confidence in dealing with software, closer scrutiny is absolutely necessary: a targeted analysis combined with a broad wealth of experience from completed classifications enable potential errors in the software, particular in its handling, to be pinpointed safely and effectively. In spite of potential errors, specific measures can be defined to increase confidence in the tool during subsequent classification of the software-based tool. Wide-ranging experience in observing tools from all development stages of the V model enables seneos to provide systematic support: both for the introduction of such a tool management process into development teams and for drafting the necessary documentation for classification and qualification and any reviews that may be required.
One of the pillars of our company philosophy is the internal and external transfer of knowledge which we achieve through training courses and workshops. Our content therein is heavily influenced by case study reports from the various projects involving ISO-compliant development and is supplemented with practical examples. This enables us to offer an attractive combination of theoretical teaching on ISO 26262 and its practical application within the development environment. The training courses on offer at the seneos Academy in the area of functional safety include:
In the case of collaboration between a supplier and an OEM, ISO 26262 expressly requires proof of quality on the part of the supplier. This includes ISO-compliant safety assessments offered by seneos as follows:
