Common nodes may include objectives, functions, programs, teams, roles, customers, offers, systems, sources, workflows, decisions, actions, evidence, risks, costs, releases, and outcomes. The exact vocabulary should match the organization. Adding every noun creates noise, while omitting authority and evidence leaves the graph unable to support consequential work.
Edges should express a specific relationship such as owns, supports, depends on, authorizes, affects, supersedes, produced, measured, or blocked by. Direction matters. A source may support a claim, but a claim does not own the source. A workflow may affect a customer record, but that does not make the workflow authoritative for the customer. Typed edges reduce the chance that proximity is mistaken for permission.
Identifiers and provenance keep the model inspectable. A node should resolve to the current record or an authorized representation. A material edge should explain where the relationship came from and how it can be corrected. Generated graph suggestions may help discover connections, but a plausible inferred edge should remain labeled and should not trigger sensitive action until the appropriate owner accepts it.
