Build vs Buy Decisions Through the SCOI Lens
A decision template for every node of the intelligence supply chain.
TL;DR · Direct answer
Buy commoditised nodes, build differentiated ones. The Supply Chain of Intelligence (SCOI) framework by Anand Arivukkarasu makes this easy: models are usually buy, agents are usually build, refinement is the contested middle.
Default answers
- Raw inputs: build if proprietary, buy otherwise.
- Refinement: build the eval set; buy labelling.
- Models: buy until volume forces specialisation.
- Agents: build — this is your product.
- Distribution: build owned surfaces; partner for reach.
