Lessons Learned in PSM I certification

I learned a lot of things when I studied and reviewed for the PSM I (Professional Scrum Master) certification.  I will share all of them here.  I thought we are implementing Scrum Process the correct way, but during my review, I learned that we are doing it wrong.

1. Scrum Master ensures that the Development Team has a Daily Scrum. He does not have to be there in the meeting.

2. Scrum Master is responsible that the Scrum framework is being adapted and used properly.

3. The intended outcomes of Daily Scrums are:
    a. Most important work to be done next for the Sprint Goal
    b. Impediments list for the Scrum Master
Not:
   a. Update of tasks and remaining work so Scrum Master can plan tomorrow
   b. A status report
   c. Updated Scrum board

4. Only the Development Team are required to attend the Daily Scrum. But if it is about who can attend, anyone can attend.

5. There is no QA role in Scrum. They are all called Development Team.

6. As soon as new work or further decomposition of work is identified, it can be added to the Sprint Backlog. Because work is equivalent to Task.

7. Scrum Master participates as a Scrum Team member in a Sprint Retrospective and facilitates is as requested or needed.

8. Product Owner participates as a Scrum Team member in a Sprint Retrospective.

9. There is no Sprint 0 in Scrum.

10. Scrum Master facilitates inspection and adaptation opportunities as requested or needed and removes impediments. They should not assign tasks with the Scrum Team, and should not escalate team conflicts to functional line managers. They should not monitor the progress of the Development Team and should not ensure the PO attends all Scrum events.
