Improving Multi-Domain Stakeholder Communication Of Embedded Safety-Critical Development Using Agile Practices: Expert Review

The development of embedded safety critical software is different from ordinary software development as such development needs to be coordinated with the hardware development. A typical embedded system project involves multi-domain experts such as business unit, software developers, hardware engineers and firmware developers. Agile methods have been successfully adopted in software engineering in general, and more recently in embedded safety critical development. A previous systematic literature review (SLR), conducted as part of this research, reported that one of the challenges of embedded safety-critical software development is multi-domain stakeholder communication. Additionally, suitable agile practices which have been used in embedded safety critical domains have been investigated. This earlier work proposed a process using a combination of suitable agile practices to support multi-domain stakeholder communication. In order to validate this proposed process, an expert review has been conducted. This paper outlines the proposed process and the findings of the expert validation.
