Information Mapping Tool

Map information domains, entities, and their relationships across the enterprise so data ownership and flow are visible before any application decisions.

Phase C, Information Systems ArchitectureDerived from TOGAF

Information domains flow from a single owner of truth to their consumers

Four domains, each traced left to right: the domain, the one accountable owner whose system is the source of truth, and the downstream systems that consume it.

Every information domain needs one accountable owner whose system is the source of truth. A domain that is no system's source of truth is contested data waiting to break a downstream process.

Information domains flow from a single owner of truth to their consumers Four horizontal tracks, one per information domain, under three lane headers: Information domain, Owner and source of truth, and Downstream consumers. Each track runs from a neutral domain panel, through an owned-by arrow, to a blue owner panel tagged Source naming the accountable team and its source-of-truth system, then through a feeds arrow to a consumers panel. Customer data is owned by the Customer team on CRM; asset data by the Asset records team on EAM; network topology by the GIS team on GIS; capacity by the Planning team on its capacity tool. A closing note in red states that each domain needs one owner, or it is contested data that breaks the downstream process that trusts it.
