Visual Maps 7–12
Map 7 — Matching Workflow Ladder
Redraw from least to most intervention:
DUPLICATE IDENTIFICATION → flag/review only
↓
MATCH-LINK → connect identity through cross-reference; source attributes intact
↓
MATCH-MERGE → reconcile attributes into unified record
Write beside the ladder: intervention / survivorship / reversal cost generally increase downward.
Source: pp. 345–346.
Map 8 — Identifier Map
Redraw:
Source A ID ─┐
Source B ID ─┼→ X-REF MAPPING + HISTORY → GLOBAL ID
Source C ID ─┘
Interpretation: Source IDs remain valid locally. Global ID represents enterprise identity. X-Ref is the traceability relationship, including merge/unmerge changes.
Answer check: X-Ref is not another identifier.
Source: pp. 346–347.
Map 9 — Hub Architecture Choice
Registry
INDEX → SORs
Data stays in source systems; registry points.
Transaction Hub
APPLICATIONS ↔ HUB = SOR
Hub owns Master Data updates.
Consolidated
SOURCE SORs → replicated/reconciled HUB = SYSTEM OF REFERENCE → consumers
Sources keep writes; hub stores shared copy.
Interpretation: Ask who owns writes and whether the central platform stores a consumer copy.
Source: pp. 349–351.
Map 10 — RDM Controlled Change
Redraw:
REQUEST → IDENTIFY STAKEHOLDERS → IDENTIFY IMPACT → DECIDE / APPROVE → UPDATE → COMMUNICATE / INFORM
Interpretation: Broad sharing makes even small changes potentially consequential. Impact assessment precedes implementation.
Source: pp. 353–357.
Map 11 — Governance Operating Loop
Redraw:
GOVERNANCE sets authority, DQ rules, use conditions, monitoring, approval gates
→ STEWARDSHIP handles content and exceptions
→ METRICS / MONITORING reveal gaps
→ IMPROVEMENT updates rules/processes
→ back to GOVERNANCE
Interpretation: Technology does not close the control loop by itself.
Source: pp. 357–359.
Map 12 — Value Evidence
Draw TRUSTWORTHY SHARED DATA in the center with seven spokes:
- DQ & compliance
- change activity
- ingestion & consumption
- SLA/service performance
- steward coverage
- total cost of ownership
- sharing volume / usage
Interpretation: Different metrics answer different management questions. Repository volume alone does not prove value.
Source: pp. 358–359.
