Which procurement method involves creating a resource internally rather than purchasing it?

The method of procurement that involves creating a resource internally rather than purchasing it is referred to as "Build." When a project team opts to build a resource, they essentially decide to utilize their own skills and capabilities to develop the necessary product or service from the ground up. This process can include designing, engineering, and producing the item, allowing for custom solutions that precisely meet the project's requirements.

This approach can be beneficial when the organization has the specific expertise, resources, and time to create what is needed without relying on external vendors. Building internally can also provide greater control over the development process, quality, and potential for innovation.
