ATM/ANS.OR.C.005(a)(2) Safety support assessment and assurance of changes to
the functional system
ED Decision 2019/022/R
ASSURANCE LEVELS
(a) The
use of assurance level concepts, e.g. design assurance levels (DALs), software
assurance levels (SWALs), hardware assurance levels (HWALs), can be helpful in
generating an appropriate and sufficient body of evidence to help establish
the required confidence in the argument.
(b) The
term ‘software assurance level (SWAL)’ is understood to be the level of rigour
of the software assurances throughout the software lifecycle. In this context,
the software life cycle is understood to be:
(1) an
ordered collection of processes determined by an organisation to be sufficient
and adequate to produce a software item;
(2) the
period of the time that begins with the decision to produce or modify a
software item and ends when the item is retired from service.
