01 — Concept Guide

Data Governance is the exercise of authority, control, and shared decision-making over the management of data assets. It answers the question: who has the right to make decisions about data, and how are those decisions made?

Without governance, data becomes ungovernable — different teams use different definitions of "customer", "revenue", and "active user". Reports contradict each other. Compliance becomes impossible. Data Governance is the system that prevents this chaos.

The DMBOK defines Data Governance as: *"The exercise of authority and control (planning, monitoring, and enforcement) over the management of data assets."*

Data Governance Office

Draft a Data Ownership Matrix

Your Scenario

You have just joined GlobalBank as a Junior Data Governance Analyst. Your manager has asked you to draft a Data Ownership Matrix for the bank's three core data domains: Customer Data, Financial Data, and Risk Data. The matrix must identify the Data Owner, Data Steward, and Data Custodian for each domain.

Instructions

  1. 1.For each of the 3 domains, identify the most appropriate senior business leader as Data Owner (e.g., Chief Risk Officer, CFO, Chief Customer Officer).
  2. 2.Identify a suitable Data Steward role for each domain — this should be a business analyst or subject matter expert, not an IT role.
  3. 3.Identify the Data Custodian for each domain — this is typically an IT/infrastructure role.
  4. 4.Write a one-sentence accountability statement for each Data Owner explaining what they are accountable for.
