Agile approach vs. V-model
Toolchain – from requirement to test case
… traceable, documented and audit-proof
In the past, software was an accessory that controlled the few functions of an actuator or sensor and prepared the necessary communication. In the age of Ethernet-based real-time protocols, functionally ever more powerful processors and constantly growing requirements, SMEs faced these challenges with additional software developers. Individual tools were purchased, but in the absence of a defined and followed software development process, releases were often difficult to plan for and software failures in the field proliferated. Changes were often implemented on demand and were often only trackable by the software developer themselves.
Part 3 of the article series discusses the software development process and the product lifecycle management environment, the documentation and development environment in which requirements can be traceably and auditorily turned into a product that can be certified according to IEC 61508 rules. What does such an environment contain? What tools are available? What integration is there between the tools?
