Mini V’s: RTI’s approach to developing safety-critical embedded software incrementally.

At RTI we developed the first safety-certifiable DDS implementation for safety and mission-critical real-world systems. RTI Connext Cert provides a tool for resource constrained real world applications. Do you want to know how RTI can certify in our application to satisfy the highest integrity levels for the ISO 26262, IEC 61508, IEC 62304, CENELEC EN 50128/50716, and ISO 21434 standards, and the ASPICE v3.1 framework? First, we tailored a generic enough process that covers all the standards using ASPICE v3.1 as the framework for it to a specific project. In order to make ASPICE incremental, we add the concept of mini v’s that allows us to work in smaller features, able to release continuously. Second, we focused on automation but not only by adding continuous integration, and have most of our test cases automated. We also reduce extra work by automating tasks, such as static reviews (i.e. coding standards compliance), automatic traceability or using AI to autogenerate a first draft of documentation such as Test Specifications, Detail Designs, etc. Third, thanks to our retrospectives at RTI, we focused on improving our process, looking for new initiatives to automate some process steps and refine our processes.
