EKE-Electronics

Safety management consultancy partnership.

“The collaboration with SSF has enabled us to successfully expand our offering to safety critical systems on board railway rolling stock. The SSF Professionals have always accomplished their tasks in a reliable an timely manner”, says Jyrki Keurulainen, CTO of Eke-Electronics.

SSF has had the opportunity to support EKE-Electronics in the development of safety critical railway systems in several implementation projects. The cooperation was initiated with specification of an in-house process for developing software intensive products according to railway safety standards and regulations. The goal was to tailor the generic process of the standards to a set of practical techniques and measures that fit to the purpose and is familiar to the developers at EKE-Electronics. Since its development, the process has evolved to form the backbone of critical (SIL) software development at the customer, that can be re-used from project to project.

In later delivery projects the cooperation has included project specific safety management consultancy. The main responsibilities of a safety manager are to plan safety activities of a project, to partially perform and partially oversee the fulfilment of the activities, and to document the activities. This work produces documents such as Safety Plan and Safety Case that are vital parts of the safety documentation of a project. In addition to design documentation, they are typically subjected to independent safety assessments, in the railway domain.

Having an external safety manager can provide important benefits to customers working in critical domains by supporting other roles such as engineering lead and project management in their tasks. Interpreting the standard requirements and fulfilling the documentation needs are no longer their responsibilities only. Instead, system architecture, detailed design, quantitative safety characteristics and other important aspects can be inspected by a critical, independent eye already before customers and safety assessment. In short, a safety manager can help your critical projects by letting other professionals focus on objectives other than safety.
