FMEA-003: Wrong Units in Report ¶

1 Status ¶

2 Failure Mode ¶

A generated report renders a value in different units than its column caption states.

3 Effect ¶

The reader takes a decision on a value that is wrong by a constant factor; the report looks perfectly plausible.

4 Cause ¶

Unit conversion happens in the presentation layer per column template, and a template can be edited without touching the conversion.

5 Severity ¶

8

6 Occurrence ¶

3

7 Detection ¶

4

8 Mitigation ¶

Attach the unit to the value in the data model so the caption and the number can never come from different places; add a report regression test comparing every column against a golden file.

9 Residual Severity ¶

8

10 Residual Occurrence ¶

1

11 Residual Detection ¶

2

12 Affected Documents ¶

13 Monitoring ¶

The golden-file report comparison runs in every build.
