3 Topics for Discussion The integration problem at Best Buy and how we are tackling it Open Source in use at Best Buy Thoughts about how Open Source could be a better path to achieving global standards

6 Off-Shore Integration Factory Analysts enter adapter specifications through a series of structured forms. The offshore factory uses the specs to assemble a fully functioning adapter from reuseable building block components. Our Our adapter framework and and off-shore factory processes have reduced interface costs by by a factor of of four. If If we we had had discovered openadapter.org 2 years ago ago before we we built built our our own own framework we we may may have used it. it. There s no no reason to to switch now.

7 The Power of Frameworks Typical Real-Time Interface Cost in 2001 Typical Real-Time Interface Cost in 2003 Interface Development Cycle Time in 2001 Interface Development Cycle Time in 2003 Number of Adapters built in the past year Adapter code re-use for the last 20 adapters Number of ETL interfaces built in May, 2003 Total number of ETL interfaces in production $20,000 $4, days 4-6 days % 550 8,765

12 Users have abdicated responsibility for standards, and vendors haven t done a great job filling the gap The great thing about software and standards; there are so many to choose from. We can learn from successes & failures: C# vs. Java, COM, Corba, J2EE Ethernet vs. Token-Ring HTTP TCP/IP CVS vs. PVCS UDDI
