Which of the following is a common customization of story cards?

The customization of story cards often reflects the team's needs and the project's specific context. One typical customization is creating an additional tab for data mapping, which allows teams to clarify data dependencies or structure and ensure all pertinent data is accounted for during development. This additional tab can provide visibility into how data flows and how different elements of the story are interconnected, facilitating clearer communication among team members and enabling more organized tracking of requirements.

Adding team member roles might not be considered a common customization of story cards since roles are usually defined outside of story cards to maintain focus on the requirements and tasks at hand. Including external links to resources can be useful, but it is more of an enhancement rather than a core customization. Relying solely on predefined templates limits flexibility, as effective story cards should evolve based on the team's learning and practices, so this is not an appropriate customization either.
