A solution must be deployed to the public quickly. The team is experienced, stakeholders support the delivery, and the customer is cooperative. Which strategy should the project manager use to ensure on-time delivery?

The correct answer is to use a high-level plan for incremental deliveries and obtain the customer's feedback as early as possible. This approach, characteristic of agile methodologies, is best suited for situations requiring quick deployment and where customer cooperation and stakeholder support are present. Incremental deliveries allow for continuous feedback and adaptation, increasing the likelihood of meeting customer needs and ensuring on-time delivery of valuable components. Meeting with the customer to agree on solution components and priorities is a good practice but doesn't fully address the "quick deployment" aspect as effectively as incremental delivery with early feedback. Asking the sponsor for additional resources might be necessary later but isn't the primary strategy for ensuring on-time delivery when the team is already experienced and stakeholders are supportive. Creating a detailed plan of all milestones, deliverables, features, and resource allocations is typical of a predictive approach, which can be too rigid and time-consuming for a project needing quick public deployment.
