Context for the reading sample
The chapter describes legacy as a relationship between change risk, change effort, and available system knowledge. It offers five signals for an initial diagnosis and discusses common countermeasures.
The sample is intended for technical decision-makers who need a shared view of a system's condition before stabilization or a rebuild. The PDF itself is in German.

- Individual signals or thresholds do not produce a supported assessment on their own. Technical and organizational context remains decisive.
- The PDF is written in German, contains 10 pages, and is dated September 22, 2026.
