One of the biggest problems from my daily work in the team is the acceptance criteria are mostly too unclearly defined. What this means in detail:
Stands inquiries, because the PO or a developer has expressed itself in the acceptance criteria again wrong or too broad
Acceptance is sometimes very difficult because acceptance criteria
have to be added
Constant post-processing of test cases by supplementing or adapting
the acceptance criteria
I have addressed the topic several times in retroperspective, but so far you can not adapt to it, or refer me to the Scrum process.
Despite my many years of experience, I am reaching my limits and unfortunately can not continue. Maybe you?
