The answer given here centres on learning from errors. The classification and evaluation of methods is strictly based on causal analyses of disasters, accidents and incidents with undesired outcome. The lifecycle model of IEC Standard 61508 has been adopted as a classification scheme. A couple of examples are given. The SRE methods considered here are those of IEC 61508. These methods are dealing with software reliability as well as with the production of highly reliable software. As an example of some more recent proposals Extreme Programming (XP) has been included.enText/Conference Paper1617-5468
