Human Machines didn't automate Walmart's existing process — they redesigned it. The team built a custom multi-agent system in which multiple AI agents work in parallel: one generating base product concepts from design briefs, others producing colorway and material variations, and additional agents scoring and filtering outputs against design standards. The system generates complete concept packages — layered assets structured for direct handoff to production — in the formats already used by Walmart's design team. No changes to the existing software stack were required. The result was a 10x acceleration in concept generation versus the previous manual process, enabling more design options to be explored before production decisions are made.
