   A customer is implementing Salesforce for a global rollout across multiple regions. The project has a fixed budget and a deadline that cannot be extended. The business requirements are expected to evolve as each region provides feedback. The customer's leadership is concerned about quality and wants to avoid rework. The architect must choose between Waterfall and Scrum. What is the most important trade-off to communicate to the customer?

   • AWaterfall is better for global rollouts because it produces a single specification, while Scrum is only suitable for small, co-located teams.
   • BWaterfall offers predictability but risks late discovery of requirement mismatches, while Scrum offers adaptability but requires active stakeholder involvement to avoid rework.
   • CScrum guarantees higher quality because of continuous testing, while Waterfall cannot achieve the same level of quality.
   • DWaterfall is faster because it avoids sprint ceremonies, while Scrum is slower due to the overhead of iterative planning.
