ECSS discipline Q-30 Dependability


This webinar covers the ECSS discipline Q-30 Dependability.

The course will introduce the requirements for dependability assurance applicable to ESA projects to the audience as well as the related compliance processes.

The ECSS dependability policy for space projects is applied by implementing a dependability assurance programme, which comprises:

  • identification of all technical risks with respect to functional needs which can lead to non-compliance with dependability requirements
  • application of analyses and design methods to ensure that dependability targets are met
  • optimization of the overall performance, cost and schedule


The ECSS Q30 discipline contains the following standards, handbooks and technical memoranda:

  • ECSS-Q-ST-30C Rev.1 – Dependability
  • ECSS-Q-ST-30-02C – Failure modes, effects (and criticality) analysis (FMEA/FMECA)
  • ECSS-Q-ST-30-09C – Availability analysis
  • ECSS-Q-ST-30-11C Rev.1 – Derating – EEE components
  • ECSS-Q-HB-30-01A – Worst case analysis
  • ECSS-Q-HB-30-03A – Human dependability handbook
  • ECSS-Q-HB-30-08A – Components reliability data sources and their use
  • ECSS-Q-TM-30-12A – End-of-life parameter drifts – EEE components




The objective of the course is to provide participants with some basic knowledge of the ECSS Q-30 Dependability requirements and of the activities to be performed in the context of ESA projects and to address their practical implementation.
