Presentation Title: Managing a Secure Requirements Engineering Flow within a Complex Product Family Environment in order to attain ISO26262 Compliance
Abstract: Managing a secure requirements engineering flow within a complex product family environment in order to attain ISO26262 compliance.

The ISO26262 standard not only drives the automotive industry towards creating safer systems within the design of its electronics components but also seeks to ensure that the processes and data management behind the implementation are also traceable and audit proof. This highlights some age old issues within the industry in relation to the quality of the requirements, the complex nature of testing to ensure correctness of the designs and the view ability and auditability of the data flow throughout an entire system.

Currently there is a drive across tooling companies to supply tools which aim to solve a lot of these issues, which in turn is also leading to an increasingly complex tool ecosystem and creating new issues relating to how to get the tools to interoperate and move or share data in a secure manner to ensure data integrity throughout the flow.

Several EU and UK based funding initiatives have been looking into how to solve these problems over the last few years. MBAT (http://www.mbat-artemis.eu/home/) was a model based initiative looking into MBSE (Model Based Systems Engineering) and Testing of Embedded systems and the use of an RTP (reference technology platform), CESAR (Cost-efficient methods and processes for Safety relevant embedded systems), again looked at Modelling and the RTP but also looked into Requirements Engineering processes and tooling. CRYSTAL (Critical System Engineering Acceleration) is the follow on project to these earlier two and is investigating pushing forward the RTP and an IOS (Interoperability Specification), largely based on OSLC and REQIF (Requirements Interchange Format). It has almost 70 European members including within automotive, Daimler, Volvo, Fiat, Valeo, Infineon, AVL, TVS as well as multiple research institutes. Other domains also involved are Avionics, Rail and Medical along with multiple tool providers including IBM, PTC, the REUSE company working on ALM and PLM solutions.

TVS will provide an overview of the issues faced when implementing a secure RE flow on a complex multiple product line family as identified within the different use-cases within the Crystal project. TVS also offer some insight into what tooling solutions are available and where and how processes and methodologies can be used to ensure a secure audit proof Requirements flow to help attain compliance with the ISO26262 standard.

Speaker Bio: Serrie Chapman gained a degree in Computing for Real time systems and spent 10 years doing hardware pre-silicon testing at IP and System level with the Infineon Tricore Microprocessor product family using a variety of random, directed and formal methodologies.
Serrie also spent time working in the background on work such as the IEEE1647 ‘e’ language standardization committee, supporting improvements in tracking and dissemination of information via change management, bug tracking, twiki documentation and requirements tracing.
In 2010 due to an emerging automotive safety standard ISO26262, mandating Requirements Engineering, Serrie changed roles to become the requirements manager for the Infineon Microcontroller AURIX Tricore product family. She is involved on two EC Funding projects relating to the standard and also to emerging interoperability tooling standards, whilst also providing knowledge and expertise on Requirements engineering solutions for quality improvement and standards compliance.
