What is Enterprise Architecture?

• What are your business priorities?
• What information / technology do you have?
  (AS-IS)
• What information / technology you need? (TO-BE)
• What is your plan to get from where you are to
  where you want to be?

Enterprise Architecture is the Plan. It
involves executive commitment, processes,
methodology, and tools

  applications used to support these processes?
• What data is needed for core business processes?

  software, and how does each component support
  business processes and data requirements?

DWH change management
4500 tables,10000 ETL flows (mainframe, RDBMS,
flat files), 600 Universes, 25000 reports, ODS,
DataMarts, Staging Area
We dont dare make any changes to our Data
Warehouse Our systems have become too complex
to understand the interdependencies enough to
understand the impact of making changes without
tools.
13
Consistent customer face and preparation for SOA
We need to be able to access all of a customers
information when ever there is an interaction.
The days of 'faking it' are over. There needs to
be a clear understanding of what all the
information that is needed to answer any inquiry,
and that information has to be readily available.

Unlocking SAP metadata

• A customer needed to better understand their data
  and how to translate that into better business
  decisions, which is why despite the downturn and
  cuts in other IT projects, the CIO and CFO saw
  the investment in PowerDesigner and was one of
  the few projects not being put on hold as part of
  their cost reduction plan in response to the
  financial crisis.

• Works with SAP, Siebel, JDEdwards, PeopleSoft,
  Oracle Apps

Ensuring compliance

• Financial Basel II, Sarbanes-Oxley
• Telco Call Data Retention
• Retail Visa Cardholder Security Program
• Govt / Health Data Privacy / Data Protection
• Where and how am I storing sensitive data?
• Which applications and business processes have
  access to this data?
• How can I get the auditors off my back quickly?

16
Improved communication
Communications between different groups has
always included a certain degree of
interpretation that is a luxury that we can no
longer afford. Ericsson
