Increasing functionality, multicore and black box integration of OEM software or park brake control supplied by third parties increased complexity of braking system development dramatically. Agile methods were introduced to handle increased complexity. With this first application of agile methods at ZF TRW we could prove feasibility and strong benefits of agile methods in safety critical system development (ASIL D), very large projects (> 150 engineers), and projects with very strong dependencies between HW (“ECU or HCU”) and SW.
Improvements were observed in much faster flow of information, better alignment of decisions, and significant improvement in velocity and product quality. Read this article with experiences of ZF and Vector on a large safety-critical transformation project.
