### Odtwórz problem

W większości przypadków problem wynika z **autorskiego kodu** osoby pytającej.

 * the fact that the problem reporter has/should not have information about the calling context and hence cannot provide
 * an expressive source hint for the model problem. Instead, the source hint is configured by the model builder before
 * it delegates to other components that potentially encounter problems. Then, the problem reporter can focus on

* In vielen Fällen ist es besser, das **zugrunde liegende Problem oder den Anwendungsfall** zu verstehen, da es möglicherweise einen besseren Weg zur Lösung gibt als das, was die Person versucht.

### Um Schließung bitten

Wenn die Person antwortet, besteht eine hohe Chance, dass Sie ihr Problem gelöst haben. Herzlichen Glückwunsch, **Sie sind ein Held**! 🦸

### Suggest solutions

* After being able to understand the question, you can give them a possible **answer**.

* In many cases, it's better to understand their **underlying problem or use case**, because there might be a better way to solve it than what they are trying to do.
