B2–C1 · SYS · 5 patterns

Systems thinking

Trace second-order effects, bottlenecks, local optimisation, and the drivers that keep a problem recurring.

01 · How to use this set

Start from the communication job

Trace second-order effects, bottlenecks, local optimisation, and the drivers that keep a problem recurring.

Read the frame, try to complete your own sentence before opening an example, then compare the English structure with its German parallel. The point is retrieval and choice, not passive list reading.

A compact sample from the 5 patterns in this study set.

01The immediate effect may be [X], while the second-order effect could be [Y].The immediate effect may be faster closure, while the second-order effect could be more reopened cases. · German parallel: Die unmittelbare Wirkung kann [X] sein, während die Wirkung zweiter Ordnung [Y] sein könnte.02This removes the bottleneck at [X], but may move it to [Y].This removes the bottleneck at data entry, but may move it to manual approval. · German parallel: Das beseitigt den Engpass bei [X], kann ihn aber zu [Y] verlagern.03Optimising [X] locally can make [Y] worse overall.Optimising ticket closure locally can make customer resolution quality worse overall. · German parallel: Wenn wir [X] lokal optimieren, kann sich [Y] insgesamt verschlechtern.04This treats the symptom [X] without changing the underlying driver [Y].This treats the symptom of duplicate records without changing the underlying driver of inconsistent identifiers. · German parallel: Das behandelt das Symptom [X], ohne den zugrunde liegenden Treiber [Y] zu verändern.05The system will keep producing [X] as long as [Y] remains unchanged.The system will keep producing duplicate work as long as ownership remains fragmented. · German parallel: Das System wird weiterhin [X] erzeugen, solange [Y] unverändert bleibt.

01Decision quality and trade-offsCompare options by explicit criteria, weigh the cost of delay, and preserve useful flexibility when certainty is impossible.02Causal diagnosisSeparate triggers from causes, compare mechanisms, and diagnose causal structure without treating sequence as proof.03Hypothesis testingTurn explanations into testable predictions, seek discriminating evidence, and revise claims when the data require it.04Metacognitive learningNotice what you recognise but cannot recall, diagnose recurring errors, and convert feedback into the next practice target.
