IBM Information Server Understanding Your Source Systems
Corporate View of Information Architecture Is Changing • Information is the key to Business Innovation • Organizations highly effective at driving information integration are 5 times more likely to drive value creation • Information architecture can’t exist in a vacuum – it needs to be tied to enterprise architecture 87% of CEOs believe fundamental change is required in next two yearsto drive innovation Over 60%of CEOs believe their organizations need to do a better job leveraging information Source: 2006 IBM Global CEO Survey
Customer Business Issues • Too much information and not knowing what’s important • Not using demand signals to drive supply chain • Not using customer analysis to tailor marketing and sales • Not leveraging valuable unstructured information • Multiple versions of the truth • Problems managing customer, product and partner interactions • Regulatory compliance inhibited by poor transparency • Lack of trusted information • Incomplete, out-of-date, inaccurate, misinterpreted data • Difficult to understand or control how information is used • Lack of agility • Inability to take advantage of opportunities for innovation • Escalating costs due to inflexible systems and changing needs
Today’s Information Challenge Organic growth, mergers & acquisitions, and compositeapplications have led to a vast and rapidly growing sea of information sources in our enterprises • Where is my information? • What does it mean? • Where is it used? How Can I Identify and Mitigate Data Risks When I Don’t Even Know Which Data I Have?

What are systems of records for Customer, Product, and Item masters? How can I access a single view of my customer records and use it to enrich my customer interactions? How do I ensure that quality measures and metrics are consistent for the master data across data sources? How do we measure product and service effectiveness, when my product definitions are not consistent? How do I ensure that replicated sources are consistent with the system of record? How do I understand whether the data is valid, accurate, and relevant? I have multiple implementations of the same application plus custom applications with their own data models; how do I exchange data between different applications? Why do we re-invent the wheel for product and customer data when we develop a new application? Key Enterprise Questions in Understanding Data In information and process driven business environments the ability to understand, standardize, and validate core enterprise information is of strategic importance. In most organizations, core information remains in data prisons, preventing a single, integrated enterprise-wide view of data across applications.

Software Architect Developer BusinessAnalyst End Users Data Architect IT Admin Data Admin Domain Expertise constantly changes Domain Expertise constantly changes • Domain expertise is critical for understanding the data, the problem and interpreting the results • “The counter resets to 0 if the number of calls exceeds N”. • “The missing values are represented by 0, but the default billed amount is 0 too.” • Insufficient domain expertise and understanding is a primary cause of poor data quality – data becomes unusable • Usually in people’s heads – seldom documented • Fragmented across organizations • Lost during personnel and project transitions • If undocumented, knowledge and understanding deteriorates and becomes fuzzy over time

Multiple database vendors. • Tens of thousands of tables, many more views… • Where is customer credit card information stored and used? • Which tables? Views? Stored Procedures? Servers? • Applications? Messages? Partner interfaces? • What does it mean? • Different names/structure for same information, no conventions • How can I modify my data architectureto provide a more sustainable solution?

The data validation report indicates a new data source is producing an unacceptable level of bad values. • “Where do we need to implement more stringent controls?”

Lessons Learned & Best Practice:Control Scope Ruthlessly / Focus on Benefits • Business must own scope • Business should be owners, not renters • IT maintains its independence by not taking sides • Controlling scope encourages project discipline • Continually Scope & Iterate • Don’t boil the ocean • Projects which try to do it all in one pass generally fail • Measure, Report, and Deliver benefits regularly • Initial projects must provide some benefit within 6 - 9 months at the minimum (even if a small benefit) • Subsequent phases should provide benefits every 3-6 months
Summary • Information understanding is becoming an increasingly important organizational issue • Most critical business initiatives depend of quality information • Improving understanding requires a focused programmatic approach including business, data, and system levels • The IBM Information Server provides all of this in a unified platform • At the core of any source system analysis is a platform capable of providing ongoing understanding IBM Information Server
