PMP Practice: Manage suppliers/contracts

Ocean Tanaka is managing a digital transformation project for Bright Ridge Labs, a pharmaceutical research company. The project includes two main components: migrating legacy compliance databases to a new cloud platform (fixed regulatory requirements, strict audit trail needed) and developing a custom analytics dashboard for research teams (evolving user needs, frequent feedback loops desired). The project sponsor has approved a hybrid approach. Ocean is now working with the procurement team to acquire vendor support. The compliance database vendor requires a detailed statement of work with fixed milestones and deliverables before providing a quote. The analytics dashboard vendor prefers working in two-week iterations with a time-and-materials arrangement. Ocean's procurement manager insists on using a single contract type for both vendors to simplify administration. What should Ocean do?
