TS EN 9115

TS EN 9115 is a supplement to EN 9100 for quality management systems in aviation, space and defence organizations that design, develop, and/or produce deliverable software and related services. It addresses software supplied as a standalone product, as embedded software, as a mobile application, as software loaded into a target computer, and as software that forms part of service offerings such as cloud environments or web-hosted solutions.

What is covered by deliverable software

In this standard, software is treated as an engineered deliverable rather than only as source code. The quality-management perspective extends across development, verification, delivery and, where applicable, maintenance activities. In general technical terms, that means process control, traceability, configuration management and disciplined handling of changes are central concerns when software is part of safety-, mission- or performance-sensitive aerospace supply chains. Supporting software used to develop and maintain deliverable software is also included where required.

Boundary with hardware description languages

The standard also clarifies applicability when Hardware Description Languages or high-level languages are used as the design source for electronic hardware such as ASICs and PLDs. In those cases, the organization and its customer and/or supplier are to agree the extent to which the supplement applies. That makes TS EN 9115 particularly relevant where software engineering practices intersect with electronic hardware design and where the software lifecycle must be managed within an aerospace quality framework.
