Off-Shore Integration Factory

The offshore factory uses the

specs to assemble a fully

functioning adapter from re-useable building

block components.

Analysts enter adapter

specifications through a series of

structured forms.

Our adapter framework and off-shore factory processes have reduced interface costs by a factor of four. If we had discovered openadapter.org 2 years ago before we built our own framework

– we may have used it. There’s no reason to switch now.

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

Few end users take an active role in standards activities - even in industry-specific initiatives

Few end users take an active role in standards activities - even in industry-specific initiatives

What‘s wrong with this picture?

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
