VYAN is a System of Intelligence

Three layers sit between transactional truth and committed action. At the bottom, Systems of Record — ERP, PLM, CRM, MES, WMS, TMS — the transactional truth as recorded. In the middle, Systems of Planning — IBP, Kinaxis, o9, Blue Yonder, Anaplan — the layer collectively responsible for the seven failures. At the top, an emerging layer: Systems of Intelligence. Decision governance, distribution-driven planning, stochastic evaluation, meta-optimization, resilience scoring, conversational interface. VYAN is the System of Intelligence.

What VYAN augments: ERP, PLM, CRM, MES, WMS, TMS. These remain. VYAN reads transaction history from them and writes back committed decisions; the relationship is bidirectional but bounded. Your S/4HANA stays. Your Salesforce stays. Your Manhattan WMS stays. The boundary is decisions versus records.

What VYAN replaces: the planning stack (IBP, Kinaxis, o9, Blue Yonder, Anaplan, the home-grown spreadsheet-and-script systems that surround them) and the control tower (Project44, FourKites, and the SoP-vendor cousins). Their architectures produce the seven failures; replacing them is the point. VYAN's event stream canvas and cockpit do what control towers do, plus the decision the control tower exists to recommend.

Master data hygiene becomes a smaller problem in operational consequence — not because VYAN replaces the MDM system, but because VYAN's stochastic treatment of lead times, yields, and capacities means the planning system stops being brittle to the master-data scalars. The ERP keeps its master data; VYAN compensates with learned distributions. The forecast engine is the rare optional augmentation — VYAN can produce probabilistic forecasts natively, or ingest yours and run the optimization on top.

The engagement model the positioning implies: parallel-run before replace. The customer's existing planning stack stays operational while VYAN runs alongside; the Policy Value Add measured against the customer's own data is the evidence on which retire/keep decisions get made. Migration is evidence-driven, not vendor-driven.
