Clarification on responsibilities of Product Owner and Scrum Master

 

1. Product Owner - Formuliert das Sprint Ziel (formulates the sprint goal)

You are correct in your interpretation of the Scrum Guide.  But remember that the Product Owner is part of the Scrum Team and is responsible for the contents/definition of the Product Backlog.  As such their contribution to the Sprint Goal would focus on the value of the items chosen from the Product Backlog.  The Development Team creates the Sprint Backlog by selecting items from the Product Backlog but no one can tell them how to work. The Sprint Goal should be focused on the Sprint Backlog, not the Product Backlog so their explanation is flawed in my opinion.

2. Scrum Master - Optimiert den Wert der Arbeit des Entwicklungsteam. (Optimizes the value of the work of the development team)

Again, your interpretation of the Scrum Guide is correct.  Again, I will add that according to the Scrum Guide, the Scrum Master provides these services to the Development Team:

• Coaching the Development Team in self-organization and cross-functionality;
• Helping the Development Team to create high-value products;

So the Scrum Master does play a part in the value of work the Development Team does but ultimately it is up to the Product Owner to ensure the items the Development Team work on optimizes the value to the stakeholders.

I applaud your interpretation of the Scrum Guide. 

the Scrum Guide is one of the topic

Is the Scrum Guide actually being read?

@Daniel, thank you for the clarification.
