Inter-enterprise System and Application Integration: A Reality Check

We Are Creating Our Own Problems, e.g., Current Standardization Efforts Are Only Increasing Complexity!

Find Out What Is Really Going on Before (re)Designing a System!

Do Not Specify More Than Strictly Needed!

Let’s Make Fuzziness Explicit!

The World Moved on

SaaS (Software as a Service)

Web 2.0

The World Really Moved on

Meaning of ‘Integration’

New World Order for Interactions Across Enterprise Information Systems in the Flat World

It Is an Illusion to Believe We Will Ever Solve All Interoperability Problems!

Understand the Driving Forces Before Integrating Systems!

Think in Long-Living Infrastructures!

This Was Just the Beginning!

Devise Conceptual “Nodes” Instead of “Leaves” Solutions!

Current EAI, WFM, and ERP Systems Are “Leaves”!

Is There Any Bright Future for EAI Solutions?

EAI Solutions Will Eventually Adopt and Use Semantics

Enterprise Application and Human Integration
