When I got first introduced to the concept of incident reports it was under the name of postmortem, as I worked for a mainly English speaking company then and didn't think twice about it. But earlier this week I mentioned it to a colleague he found it a rather macabre term for something like an incident report. When you think of it, nothing really died (maybe some engineers died a little inside that their design was not as 100% reliable as they though). But for the rest it was just a temporary state, nothing permanent like death. All other uses (eg: medical) of this word all seem to relate strictly to death.
Maybe it is because incident reports just sound to formal or is there a etymology of this term in the IT world?
