“…This examination revealed that none of the Scrum practices contradict regulatory requirements. To further reinforce the decision to adopt Scrum practices, the findings of the mapping study revealed that where agile practices have been adopted when developing medical device software, they have typically been Scrum practices [14][15][16][17][18].…”

Abstract. Three surveys conducted over a 6 year period revealed that medical device software organisations have difficulties in the area of requirements management, namely accommodating changes in requirements. Medical device software is traditionally developed in accordance with a plan driven software development lifecycle (SDLC). These SDLCs are rigid and inflexible to changes once the requirements management stage has been completed. Agile methods are gaining momentum in non-regulated industries but as of yet, the adoption of these methods in regulated industries such as the medical device software domain remains low. This study presents an implementation of agile methods within a medical device software development organisation based in Ireland. This implementation involved integrating agile practices with a traditional plan driven SDLC. Upon completing this implementation within a medical device software development project, the organisation identified cost savings and a reduction in the rework required when introducing a change in requirements.

Lately, agile methods have widely been used in large organizations. This contrasts to previous practice, where they were mainly used for small projects. However, developers of safety critical systems have shied away from using these methods for the right and wrong reasons. Adoption of agile methods for safety critical system development is low and there is need to find out why this is so especially since agile methods allow a more relaxed approach towards documentation, flexible development lifecycle based on short iterations and accommodates changing requirements. This paper presents a report of a detailed analysis of literature and aims to shed light on the suitability of agile methods for developing safety critical systems .The findings indicate that many organizations are relying on traditional methods to develop safety critical systems because they are familiar with them and have been thoroughly tested over time. However with the advent of agile methods there is a paradigm shift by non safety critical system developers, nevertheless this is not happening with the safety critical system developers and there is need to find out why.

“…In another study Ge and et al, propose an iterative approach for developing safety-critical software [7]. First they address the notion of up-front design in safety critical software development, and describe the characteristics of an up-front design that is minimal from perspective of achieving safety objectives.…”

Nowadays software control large majority of systems that humankind use. Systems that software is used widely, such as transportation, military, medicine and avionics must be safe during operation. Fail in these critical systems may cause catastrophic results (i.e. loss of human life, loss or severe damage to environment or equipment etc.). In order to avoid failure on safety critical systems or at least mitigate risks detailed testing is required. Many safety critical systems are developed with sequential phases and tested with test last approach. But test last approach is not sufficient when requirements are unclear or changed. To overcome weaknesses of test last approach we propose test driven approach for safety critical software development, regulated by IEC 61508 standard. A systematic analysis of IEC 61508 software requirements against proposed approach showed that the approach directly supports some objectives and partially supports some of them. Supported objectives are safety requirement identification, simple and testable software design, verification and validation. In general introduced approach suits regulated software development well and this paper outlines these details.
