Adopting Agile Practices when Developing Medical Device Software

Agile methods are gaining momentum amongst the developers of non-safety critical software. They offer the ability to improve development time, increase quality and reduce development costs. Despite this, the rate of adoption of agile methods within safety critical domains remains low. On face value agile methods appear to be contradictory to regulatory requirements. However while they may appear contradictory, they align on key values such as the development of the highest quality software. To demonstrate that agile methods could in fact be adopted when developing regulatory compliant software they were implemented on a medical device software development project. This implementation showed that not only can agile methods be successfully followed, but it also revealed that benefits were acquired. For example, the medical device software development project was completed 7% faster when following agile methods, when compared to if it had been completed in accordance with a plan-driven approach. While this implementation is confined to a single project, within a single organization it does strengthen the belief that adopting agile methods within regulated domains can reap the same benefits as those acquired in non-safety critical domains.

Barriers to Adopting Agile Practices when Developing Medical Device Software

Agile methodologies such as XP and Scrum are founded upon the four values and twelve principles of agile software development. A software development project is only considered to be truly agile if these values and principles are followed. However, software developed for use in medical devices must be regulatory compliant and this can make the process of following a single agile methodology such as XP difficult to achieve. This paper outlines how we identified the barriers to agile adoption in the medical device software domain through performing a survey. These barriers include: lack of documentation; maintaining traceability; regulatory compliance; lack of up front planning and the process of managing multiple releases. Based on this research recommendations are also made as to how these barriers can be overcome.

Integrating Agile Practices with a Medical Device Software Development Lifecycle

The rate at which agile software development practices are being adopted is growing rapidly. Agile software development practices and methodologies appear to offer the silver bullet which can solve the problems associated with following plan driven software development lifecycles. Agile software development practices offer the possibility of achieving lower development costs, increased efficiency and improved software quality. However, there is currently a low rate of publicly available information that suggests there is widespread adoption of agile practices within the medical device software domain. This is largely due to the fact that software developed for medical devices includes challenges not faced when developing non safety critical software. As a result of these challenges, medical device software is typically developed using plan driven software development lifecycles. However, such lifecycles are quite rigid and cannot accommodate changes easily. Previous research has revealed that medical device software development projects can benefit from adopting agile practices whilst still maintaining the discipline associated with following plan driven development lifecycles. This paper outlines the challenges faced by developers when developing medical device software and how shortcomings in both agile and plan driven approaches can be resolved by following a mixed method approach to medical device software development.

Integrating Agile Practices with Plan-Driven Medical Device Software Development

The popularity of Agile software development is growing rapidly with an increasing number of projects being developed following Agile methodologies such as Scrum and XP [1]. Research has revealed that following Agile practices when developing software can have a significantly positive impact in reducing development time, reducing cost and increasing overall quality [2-4]. Whilst Agile practices can have a positive impact on a development project there are incompatibilities between Agile methodologies and the plan driven approaches followed when developing safety critical software [5, 6]. However, it has been recognised that “formal techniques may be used in an agile way” [5]. Case studies have been performed in organisations developing safety critical software which validate this statement [7-9]. This Ph.D. is focusing on the area of medical device software development and integrating Agile software development principles into traditional plan driven lifecycles for use in developing medical device software

Combining Agile and Traditional Methodologies in Medical Information Systems Development Process

2016

Having experience with different traditional and agile methodologies in medical information system development and upgrade projects, we support the statement that no single methodology can be used with its full potential in all cases. Instead, mentioned methodologies have their own place in complex software projects and within certain category of sub-projects give the best results. In this paper we presented the guideline on choosing adequate methodology in different development and upgrade projects. All examined projects are defined within the scope of larger medical information system called Medis.NET developed by our research group, and deployed in 30 healthcare institutions. The bottom-line is that during requirement collection we rely on model and feature driven development supported by automatic code generation tools, which lead to faster prototype generation. Next, dividing the set of functionalities to sub-projects we group them in three categories – core projects, userorien...
