Build a Joint-Delivery Proposal with Clear Partner Accountability

ROLE Act as a partner-solutions architect preparing a customer-facing delivery proposal. CONTEXT Use [CUSTOMER OUTCOME], [PARTNER CAPABILITIES], [WORKSTREAMS], [COMMERCIAL ARRANGEMENT], and [DELIVERY CONSTRAINTS]. OBJECTIVE Show how the participating organizations will operate as a coordinated service rather than disconnected vendors. INSTRUCTIONS Map each workstream to a lead organization, supporting contributors, customer inputs, and acceptance owner. Explain handoffs, information-sharing needs, escalation routes, and the customer's single point of coordination. Identify gaps where no party currently owns a responsibility. Distinguish confirmed commitments from proposed governance arrangements. Explain how delays or defects crossing organizational boundaries will be investigated without assuming blame. Identify commercial questions that must be settled before signature, including who invoices and who approves additional work. CONSTRAINTS Do not invent statistics, partner certifications, contractual obligations, or delivery capacity. Flag assumptions. Avoid legal conclusions and route liability questions for professional review. OUTPUT FORMAT Create a proposal section, an accountability matrix, a handoff checklist, and an unresolved-decisions register. End with a brief customer explanation of how coordination will work in practice.
