Who did you clarify the requirements for the new acceptance stage with?

When clarifying requirements for a new acceptance phase, I usually consult several key participants:

• Customer or business representative — to understand business goals and expectations.
• Project manager — to coordinate timelines and resources.
• Technical architect or lead developer — to assess technical constraints and possibilities.
• QA engineers — to understand acceptance criteria and testing.

It is important to communicate with those who are directly responsible for decision-making and have complete information about the requirements. If there are doubts, I clarify details through official communication channels (such as emails, meetings, documentation).
