Corporate Structure and Sourcing Models

Named models describing how a firm structures the scope of its own operations or sources a business function, including contracting an external provider to run a business process, acquiring or combining with firms performing the same stage of production, and acquiring or combining with firms at different stages of the same supply chain. Belongs here: any model whose defining act is a structural decision about what the firm itself does in house versus contracts out, or how it expands its scope. Does not belong here: a named event describing one specific completed transaction, which is a corporate-event entity rather than a business-model entity in this atlas.
