2. The IT landscape is littered with legacy, packaged and developed applications, coupled with unstructured data. The uncontrolled silos of data make managing information very difficult and limit its strategic value. 16-2

4. © 2012 Pearson Education, Inc. Publishing as Prentice Hall 16-4 MDM is an application-independent process that describes, owns, and manages core business data entities. MDM ensures the consistency and accuracy of these data by providing a single set of guidelines for their management and thereby creates a common view of key data.

6. © 2012 Pearson Education, Inc. Publishing as Prentice Hall Information Management (IM) covers all forms of information needed and produced by the business. The IM strategy and principles structure, secure, and improve information assets. IM strategy and principles provide the context in which MDM is accomplished 16-6

7. © 2012 Pearson Education, Inc. Publishing as Prentice Hall The IM strategy and principles should be important contributors to the enterprise architecture. Information and architecture should be as separate as possible. The establishment of a dialogue and discipline for core corporate data will provide the highest value. 16-7

8. © 2012 Pearson Education, Inc. Publishing as Prentice Hall Data management (DM) is the critical work of making decisions about data. Information stewards are responsible for DM and check the accuracy, timelines, life cycle, and redundancy of the data. MDM is a subset of DM that focuses on core data. 16-8

9. © 2012 Pearson Education, Inc. Publishing as Prentice Hall Data quality aims to ensure data are correct, complete, current, and consistent. It is possible to have data quality without DM, but it is not possible to have data DM without data quality. MDM efforts focus the costs and challenges of data quality on the core data. 16-9

10. © 2012 Pearson Education, Inc. Publishing as Prentice Hall The goal of data integration is to create a data warehouse as a credible source of integrated information. Data integration serves two purposes: Enables data to be combined and collected in a warehouse. Consolidates data that are not deemed to be core but which are created and updated by several applications. 16-10

11. © 2012 Pearson Education, Inc. Publishing as Prentice Hall A single source of a company’s data provides: Better information Cost savings Improved business capabilities Improved technical capabilities 16-11

12. © 2012 Pearson Education, Inc. Publishing as Prentice Hall Better information Improves compliance reporting, generates operational efficiencies, and achieves competitive differentiation. 16-12

13. © 2012 Pearson Education, Inc. Publishing as Prentice Hall Cost savings Two main costs can be avoided by better DM: --Costs caused by poor data quality (e.g., need to verify data, poor decisions). --Costs caused by assuring data quality (e.g., prevent, detect, or repair poor data). 16-13

14. © 2012 Pearson Education, Inc. Publishing as Prentice Hall Improved business capabilities A single source of data can improve customer service (e.g., ensuring customer privacy) and support flexibility (e.g., supporting globalization, acquisitions). 16-14

15. © 2012 Pearson Education, Inc. Publishing as Prentice Hall Improved technical capabilities A single source of data can eliminate data redundancy and facilitate integration. MDM is the prerequisite of a service- oriented architecture. 16-15

17. © 2012 Pearson Education, Inc. Publishing as Prentice Hall Develop an enterprise information policy It is essential to delineate the principles around issues such as corporate data objectives, data ownership and accountability, privacy, security, and risk management. 16-17

18. © 2012 Pearson Education, Inc. Publishing as Prentice Hall Business ownership All stakeholders must be involved in MDM or political problems will likely ensue (e.g., executive and business sponsorship, data stewards, change management specialists). 16-18

19. © 2012 Pearson Education, Inc. Publishing as Prentice Hall Governance A cross-functional and collaborative IT and business data governance process should be established. “MDM can’t be sustained without governance”. 16-19

20. © 2012 Pearson Education, Inc. Publishing as Prentice Hall The role of IT DM is primarily a nontechnical problem; however technology and IT staff play important roles: --IT staff has the skills to develop a data strategy, model the data, and assess applications. --Technology maintains data models and repositories. 16-20

21. © 2012 Pearson Education, Inc. Publishing as Prentice Hall Stage 1. “I admit I’ve got data, so I’ll inventory it.” Stage 2. “Let’s identify what data is used by which application and processes. I’ll discuss the role of information and ownership.” Stage 3. “Let’s limit how much data we move around and maybe design some information exchange requirements.” 16-21

22. © 2012 Pearson Education, Inc. Publishing as Prentice Hall MDM is wrapper for concepts and issues that have been afflicting IT for long time. MDM initiative needs a thorough planning and an incremental approach: Identify some small, quick wins. Focus efforts on one type of data. Learn with the business how to manage process. Develop and continually revisit and information roadmap and strategy. 16-22
