In Agile and iterative environments, delivering a minimum viable product (MVP) or feature is a smart way to provide early value while buying time to complete more complex integration work. Planning for a partial but functional feature allows stakeholders to see progress and provides flexibility in managing dependencies between teams. The Agile Practice Guide emphasizes delivering value early and often, and using MVPs to respond to fast- changing business needs. Option B delays delivery and reduces responsiveness. Option C ignores the urgency of marketing's request. Option D halts progress and disrupts the current release.
