• Confusion as to the system's value
– Users lack confidence
– Business did not know how to use  
"the MDM"
• General agreement
– Restart the effort
• "Root cause" analysis
– Consensus
– Poor quality data
• Response
– Get data quality-ing!
• Inexperienced
– Immature data quality practices
– Tool/technological focus
– Purchased a data quality tool

– as opposed to mobile device management
• Gartner holds that MDM is a discipline
– "… where the business and the IT organization work  
together to ensure the uniformity, accuracy, semantic  
persistence, stewardship and accountability of the  
enterprise's official, shared master data"
• Sold as solution
• Official, consistent set of identifiers - examples of these core
entities include:
– Parties (customers, prospects, people, citizens, employees, vendors, suppliers,
trading partners, individuals, organizations, citizens, patients, vendors, supplies,
business partners, competitors, students, products, financial structures *LEI*)
– Places (locations, offices, regional alignments, geographies)
– Things (accounts, assets, policies, products, services)
• Provide context for transactions
• From the term "Master File"
Master Data Management Definition
15
Wikipedia: Golden Version
• In software development:
– The Golden Master is usually the RTM (Released to Manufacturing)
version, and therefore the commercial version. It represents the
development stage of "RTM" (Released To Manufacturing), often
referred to as "going gold", or "gone golden".
– Often confused with "gold master" which refers to a physical
recording entity such as that sent to a manufacturing plant.
• In data management:
– It is the data value representing the  
"correct" answer to the business question
• Definition-Reference/Master Data Management
– Planning, implementation and control activities to ensure
consistency with a "golden version" of contextual data values.

Definition: Reference Data Management
• Control over defined domain values (also known as
vocabularies), including:
• Control over standardized terms, code values and other
unique identifiers;
• Business definitions for each value, business relationships
within and across domain value lists, and the;
• Consistent, shared use of  
accurate, timely and  
relevant reference data  
values to classify and  
categorize data.
Reference Data
• Reference Data:
– Data used to classify or categorize other data, the value
domain
– Order status: new, in progress, closed, cancelled
– Two-letter USPS state code abbreviations (VA)
• Reference Data Sets
18
US United States
GB (not UK) United Kingdom

Definition: Master Data Management
Control over master data
values to enable
consistent, shared,
contextual use across
systems, of the most
accurate, timely and
relevant version of truth
about essential business
entities.
19
Master Data
• Data about business entities providing context
for transactions but not limited to pre-defined
values
• Business rules dictate format and allowable
ranges
– Parties (individuals, organizations, customers,
citizens, patients, vendors, supplies, business
partners, competitors, employees, students)
– Locations, products, financial structures
• From the term Master File
20

Reference Data versus Master Data
21
• Reference Data:
– Control over defined
domain values
(vocabularies) for
standardized terms,
code values, and other
unique identifiers
– The fact that we
maintain 9 possible
gender codes
• Master Data:
– Control over master data
values to enable
consistent, shared,
contextual use across
systems
– The "golden" source of
the gender of your
customer "Pat"
Both provide the context
for transaction data
22

Reference Data Facts 2012
• Home-grown reference data solutions predominate,
putting institutions at risk for meeting regulatory
constraints
• Risk management is seen as a more important
business driver for improving data quality than cost

• Global industry-wide survey of
reference data professionals
• Results show: Poor quality of
reference data continues to
create major problems for
financial institutions.
Reference Data Facts 2012, cont’d
• Despite recommended practices of centralizing
reference data operations, 31% of the firms surveyed
still manage data locally
• New and changing regulatory requirements have
prompted many financial service companies to re-
evaluate their reference data strategies. To prepare
for new regulations,  
nearly 62% of survey  
respondents are planning  
to extend or customize  
their reference data  
systems during 2012 and 2013.

MDM Failure Root-Causes
• 30% of MDM programs are regarded as failures
• 70% of SOA projects in complex, heterogeneous environments
had failed to yield the expected business benefits unless MDM is
included
• Root-causes of failures:
– 80% percent of MDM initiatives fail because of ineffective leadership,
underestimated magnitudes or an inability to deal with the cultural impact of the
change
– MDM was implemented as a technology or as a project
– MDM was an Enterprise Data Warehouse (EDW) or an ERP
– MDM was an IT Effort
– MDM is separate to data governance and data quality
– MDM initiatives are implemented with inappropriate technology
– Internal politics and the silo mentality impede the MDM initiatives

Guiding Principles
1. Shared R/M data belong to  
the organization.
2. R/M data management is an  
on-going data quality improve- 
ment program – goals cannot  
be achieved by 1 project alone.
3. Business data stewards are the authorities
accountable at determining the golden values.
4. Golden values represent the "best" sources.
5. Replicate master data values only from golden
sources.
6. Reference data changes require formal change
management
50

10 Best Practices for MDM
1. Active, involved executive sponsorship
2. The business should own the data
governance process and the MDM or
CDI project
3. Strong project management and
organizational change management
4. Use a holistic approach - people,
process, technology and information:
5. Build your processes to be ongoing
and repeatable, supporting continuous
improvement

10 Best Practices for MDM, cont’d
6. Management needs to recognize the
importance of a dedicated team of
data stewards
7. Understand your MDM hub's data
model and how it integrates with your
internal source systems and external
content providers
8. Resist the urge to customize
9. Stay current with vendor-provided
patches
10.Test, test, test and then test again.

15 MDM Success Factors
1. Success is more likely and
more frequently observed once
users and prospects
understand the limitations and
strengths of MDM.
2. Taking small steps and
remaining educated on where
the MDM market and
technology vendors are will
increase longer-term success
with MDM.
3. Set the right expectations for
MDM initiative to help assure
long-term success.
4. Long-term MDM success
requires the involvement of the
information architect.
5. Create a governance
framework to ensure that
individuals manage master data
in a desirable manner.
6. Strong alignment with the
organization's business vision,
demonstrated by measuring the
program's ongoing value, will
underpin MDM success.
7. Use a strategic MDM
framework through all stages of
the MDM program activity cycle
— strategize, evaluate, execute
and review.

15 MDM Success Factors
55
8. Gain high-level business
sponsorship for the MDM
program, and build strong
stakeholder support.
9. Start by creating an MDM
vision and a strategy that
closely aligns to the
organization’s business vision.
10.Use an MDM metrics hierarchy
to communicate standards for
success, and to objectively
measure progress.
11.Use a business case
development process to
increase business
engagement. 
12.Get the business to propose
and own the KPIs; articulate
the success of this scenario.
13.Measure the situation before
and after the MDM
implementation to determine
the change.
14.Translate the change in metrics
into financial results.
15.The business and IT
organization should work
together to achieve a single
view of master data.
