Splitting User Stories

Correct Answer: Split the story into multiple user stories. Each story delivers a basic version of the feature with the additional capacity to add one specific customization.

The best approach when dealing with a large user story in Agile development is to split it into smaller, manageable chunks. So the correct answer is 'Split the story into multiple user stories. Each story delivers a basic version of the feature with the additional capacity to add one specific customization.' This way, each customized version of the feature can be developed, reviewed, tested, and potentially shipped independently of the others. `Splitting it based on development tasks such as designing, coding, testing, etc.` is a common mistake as user stories should be feature oriented, not task-oriented. `Do not split it and work overtime to complete it within a single sprint.` is not recommended since this defies the Agile principles of sustainable development. Lastly, `Select one customization to be done now and postpone the others indefinitely.` fails to deliver the highly customizable feature that the user story implies and does not respect the Agile intent to best satisfy the customer.

Correct Answer: Split the story into smaller increments, each delivering a usable part of the machine learning solution.

The best action to take when confronted with a large user story that seems beyond the scope of a sprint is to divide it into smaller, manageable increments. Each segment should still deliver a functional aspect of the machine learning solution. This way, the task becomes less daunting and the team can progressively build upon each completed part. The approach of postponing the story until all other sprint stories are complete might cause delays and is not efficient. The idea of splitting the story based on different machine learning algorithms does not ensure that each part is manageable or deliverable within a sprint. Finally, assigning all developers to focus solely on one story disregards the concept of dividing work and concurrent development, leading to potential idling concerning other tasks.

Correct Answer: Incorporate the unfinished User Story into the next Sprint backlog for completion, ensuring it's adequately broken down.

The correct action when a User Story is not completed due to improper splitting is to carry it over into the next Sprint Backlog and ensure it is split adequately this time. Reprioritizing it to the bottom of the Product Backlog could delay important features. Conducting a retrospective focused only on splitting does not address the immediate need to complete the User Story. Starting a new Sprint immediately disrupts the established Sprint cycle and is not in line with Scrum practices.
