5. THE VALUE OF CLEAN DATA
DIRTY DATA CAN LEAD TO COSTLY DECISIONS

6. The Impact of Clean Data
While we know that dirty water can
impact the health of people,
We don’t as easily accept or recognize that
dirty data can impact the health of companies..

7. The Problem of Bad Data

8. Building a Clean Data Practice
Establishing a Clean Data
Practice is dependent
upon a strong foundational
Data Platform

9. THE RIGHT REASONS
CONSIDERATIONS FOR YOUR DATA PLATFORM

10. Use Case Considerations
Compliance Reporting
Governed data produces certified results that ensure no miscues in both internal and external reporting
Impact Analysis
Change management can easily trace and identify any impacts to data consumers
Digital Transformation
Architecture should leverage a hub and spoke model to enable domain based micro service builds
System Replacement
Converting to a new system should leverage clean data as part of any data import activities
Growth By Acquisition
Requires a data strategy that supports a consolidated view of data across multiple data sources

11. MAKING THE DISTINCTION
SINGLE SOURCE OF TRUTH VS BEST VERSION OF TRUTH

12. Making the Distinction
Single Source of Truth Best Version of Truth
Data storage principle to always source
information from a single source
Multiple sources of similar data across
transactional systems
Enables transparency, traceability, and
clear ownership of the data
Impacts timeliness and completeness of
enterprise data
Data usage principle for a single agreed
upon view of data
Requires a governed Master Data
Management stewardship
Results in certified “trusted” data for all
data consumption needs
Utilize business rules to eliminate data
redundancy and define metrics
