Build-Buy-Partner Framework — Definition (Glossary)
The build-buy-partner framework is a structured decision rubric for sourcing each AI capability an organization considers deploying: build it internally, buy it off-the-shelf, or partner with a specialist. The framework forces an explicit answer per capability rather than defaulting to build (typical for engineering-heavy organizations) or defaulting to buy (typical for IT-led organizations).
The three options are distinguished by who owns development, operations, and IP: build means the internal team owns everything; buy means a vendor owns the platform and the organization owns the configuration; partner means an external specialist builds on shared infrastructure with the organization retaining data and business-logic ownership.
For agent-specific guidance on the binary build-or-buy choice, see Build vs Buy AI Agents. For the full three-way framework with the partner dimension analyzed as the primary differentiator, see Build vs Buy vs Partner AI.
