Review Build vs. Buy

Build vs. buy is the decision whether to create and operate a capability internally, acquire it from a vendor, or combine purchased and internally developed components.

The choice compares more than initial price. It includes fit, speed, skills, data, control, integration, maintenance, risk, dependency, and the cost of changing direction later.

AI services can be quick to acquire while creating long-term data, vendor, and workflow dependencies. Internal builds can offer control while adding substantial operating responsibility.

A company compares a vendor document assistant with an internal retrieval application built on a model API and its own access controls.

Build and buy are not always binary choices. Most systems combine vendor infrastructure, open components, internal data, and custom workflow design.

Choose which capabilities to own and which dependencies to accept.
