Present a packaging trial without a false causal conclusion
Beobachtung, Erklärung und nächsten Prüfschritt trennen
Distinguish elapsed time from person-time and limited feedback from a general effectiveness claim.
A shorter elapsed period with two workers is not automatically less total labour time than a longer period with one. Changed staffing and order composition prevent isolating the packaging effect. Unequal, unfinished observation periods and three interviews cannot establish universal damage prevention or customer satisfaction.
Die verstrichene Zeit ist nicht die Summe der eingesetzten Arbeitszeit.
Elapsed time is not the sum of the labour time used.
Die Besetzung und die Auftragsmischung haben sich verändert.
Staffing and the mix of orders changed.
Die Wirkung lässt sich dem Material nicht eindeutig zuschreiben.
The effect cannot be attributed unambiguously to the material.
Die Beobachtungszeiträume sind noch nicht abgeschlossen.
The observation periods have not yet ended.
Drei Rückmeldungen bilden nicht alle Kundenerfahrungen ab.
Three responses do not represent every customer experience.
Ein vorgeschlagener Prüfschritt ist noch kein neues Ergebnis.
A proposed check is not yet a new result.

Unequal, unfinished observation periods and three interviews cannot establish universal damage prevention or customer satisfaction.
Distinguish elapsed time from person-time and limited feedback from a general effectiveness claim.
Do not equate elapsed time with summed person-time, treat a proposed controlled comparison as completed or convert three opinions into all customers’ views.
Attribute observations to their measured unit and group. Jeweils means each of the two groups separately here. Daraus lässt sich nicht eindeutig ableiten marks an inference limit; it does not claim that the proposed effect is impossible.
Write a 250–300-word German briefing for the team. State the useful observations, explain why the causal headline overreaches and propose a more comparable next trial. Distinguish your recommendation from evidence already collected.
