How many life cycles are typically involved per user story?

In agile methodologies, a user story typically goes through one life cycle from creation to completion. This life cycle begins when the user story is defined and added to the backlog, continues through its prioritization, refinement, and development, and concludes when the user story is delivered and accepted.

The life cycle of a user story encompasses key stages such as gathering requirements, discussions with stakeholders to clarify acceptance criteria, implementation by the development team, and finally testing and verification to ensure that the story meets the predefined acceptance criteria. This streamlined process ensures that the focus remains on delivering valuable functionality to users in a timely manner.

While it's possible to have various iterations or enhancements based on feedback after a user story has been delivered, these would typically be treated as new user stories rather than additional life cycles for the original one. Thus, one complete life cycle is the standard approach associated with user stories in Agile development.
