scope:

PURPOSE

The purpose of this document is to provide a standardised review and classification system for event data, collected during a period of interest, and to give guidance on how the classified data can be analysed to support claims in respect of the dependability requirements.

It is not intended that this document will cover the levels and types of staff required at classification meetings, analysis techniques for the classified data or provide a template from which a functional breakdown and failure definitions can simply be selected, nor can it give a step by step guide to cover every eventuality. It will consider in Annexes 2 and 3 the concepts, issues and factors that influence how failure definitions can be developed and how functional breakdown can be undertaken, whilst the main document will give guidance on how dependability events can be classified.

This document supports ADMP-01 and ADMP-02, as the event classification process may be implemented at any phase of the life cycle i.e. during development production, utilization and support phases.
