Applying the INVEST technique to this user story, including its acceptance criteria, which of the following statements is correct? SELECT ONE OPTION
Correct Answer: B
According to the INVEST criteria, the Testable and Small criteria have not been satisfied for the user story provided. Option B is correct. * INVEST Criteria: The INVEST model stipulates that user stories should be Independent, Negotiable, Valuable, Estimable, Small, and Testable. * Analysis of the User Story: The scope of the user story and its acceptance criteria suggests it is too broad (thus not 'Small') and the details provided, especially regarding response times and system notifications, imply potential challenges in effectively testing the story (thus possibly not 'Testable') without further refinement or breaking down the story into smaller, more manageable pieces. The size and complexity of the requirements indicate that the story might be better classified as an epic, needing decomposition into smaller, more specific user stories that can be more feasibly addressed within agile iterations .
