What happens in the sprint after task estimation?

After the sprint tasks are evaluated, the following occurs:

• Sprint Planning: The team selects tasks from the product backlog to complete during the sprint. The sprint goal and ways to achieve it are defined. Large tasks are broken down, and readiness criteria are clarified.
• Daily Stand-ups (Daily Scrums): The team meets daily to synchronize, discuss progress, identify and remove obstacles. Each participant answers: "What did I do yesterday, what will I do today, are there any blockers?".
• Task Execution: Team members work on the selected tasks. QA actively participates in testing, interacts with developers, writes test scenarios, automates tests.
• Backlog Refinement: During the sprint (usually short), the team may prepare the backlog for subsequent sprints: detailing and estimating new tasks, clarifying acceptance criteria.
• Sprint Review: At the end of the sprint, the team demonstrates the completed, "ready" functionality to stakeholders (product owner, customers). Feedback is received.
• Sprint Retrospective: The team analyzes the past sprint, discusses what went well, what can be improved, and plans actions to improve the process in the next sprint.

It is important to maintain constant communication and collaboration throughout the sprint. QA works closely with developers, the product owner, and other team members.
