What best describes the 'all-in' approach to timeboxing requirements?

The 'all-in' approach to timeboxing requirements is characterized by starting with a comprehensive set of eligible requirements, then systematically narrowing this set down by removing items until the schedule constraints are met. This method emphasizes capturing all potential requirements initially to ensure that the complete scope is considered. From there, it allows for a strategic reduction based on priority, feasibility, or importance, ensuring that the most vital elements are retained while accommodating time limitations.

In essence, this approach ensures that the initial understanding of what could be included is thorough, allowing the business analyst to make informed decisions about what should ultimately be prioritized. By beginning with all suitable requirements, there's an assurance that nothing important is overlooked at the onset, providing a stable foundation for subsequent iterations or adjustments based on project needs or stakeholder feedback.
