Explanation
The best way for a business analyst to handle disruptions to the project from urgent requests by the marketing director is to interpret them as guidelines to be used when determining priorities for the upcoming release.
This will help them balance between meeting stakeholder expectations and following scrum methodology principles. Focusing on agreed upon deliverables instead of new requests may ignore changing business needs or miss opportunities for improvement. Asking for an additional resource to implement new requests may increase complexity or cost without adding value or quality. References:
