I think that's what that means, for all intents and purposes..

To me, this sounds like a defect / error is included in a log file that will be sent to the client. And the structure of this log file consists of a number (for the defect) and a description of the problem.

Isn't this in fact about the way in which the information is presented?

Perhaps it is just me, but I found it difficult to visualise what was actually going on here reading the brief snippet provided. Googling the phrase and finding several examples of the actual test reports prepared by the company in question helped a lot. I won't post a link here as Sebastien has been careful to conceal the names, but the documents are easy to find.

This phrase comes from the General section of the introduction to the test report, describing the layout/presentation/format of what follows.

So, perhaps something along the lines of:
- the defects/deficiencies identified/found are reported/presented in/using the following format
- the defects/deficiencies identified/found are presented as follows in this report

I've put a low CL as my suggestion could definitely be improved upon (and the whole thing would work better if the German said die Ergebnisse rather than Festgestellte Mängel), but I do think this is the sense.
