You have been asked to lead delivery planning for a new web application that will process highly sensitive financial data. The product is strategically important because it will support customer onboarding, transaction review, and reporting for regulated clients, but the first release must ship on an aggressive timeline while meeting strict security and audit expectations. The architecture is not starting from zero: some shared platform services already exist, but identity, logging, key management, and data access patterns are inconsistent across teams. Security leadership wants strong controls from day one, while the business sponsor is pushing to keep scope tight enough to hit the launch date. You also need a practical path to recover quickly if a production control fails or a critical dependency is delayed.
How would you plan and execute delivery of a secure architecture for this application, including the roadmap, key trade-offs, success criteria, major risks, and rollback approach?
