The correct answer is C. configured in the application .
In a Guidewire InsuranceSuite project, User Story Cards are used as living requirement artifacts. They are refined over time as the team gains clarity about business needs, product fit, configuration choices, and implementation details. Their purpose is not just to capture business intent at a high level, but also to describe how that intent is translated into solution behavior within the InsuranceSuite application.
This is why the phrase that best completes the statement is “configured in the application.” In the Guidewire analyst approach, story cards help track what the project team intends to deliver and what has already been addressed in the system configuration. Since Guidewire implementations emphasize configuration of base product capabilities wherever possible, story cards are closely tied to application behavior and business functionality.
The other options do not fit the role of User Story Cards as accurately. A is incorrect because external validation may occur during review or testing, but that is not the core thing story cards specify. B is less precise because the Guidewire approach focuses first on what is configured in the product, not simply what developers implement. D is incorrect because a testing strategy is a separate project artifact, not the main content of a story card. E and F are also unrelated to the primary purpose of story cards.
So, in Guidewire terminology and project practice, User Story Cards are refined to reflect changing requirements and to specify what will be, or has been, configured in the application for the project.
