Human problems abound in Internet connectivity

• Errors, omissions and interpretations caused incompatibility
• Schedules, resources and time differ between participants
• Communication difficulties among invested individuals re-inforce the "not my problem" view.
• Knowledge is limited to one's personal domain

Applications interpret data differently

Names for data objects are often the same, but the use, meaning or intent of the data differs.

Internet projects are justified on scaling connections to partners, but…

• Testing is typically 33% of any project cost
• First connection is ~35% of testing
• 50% declining to 25% of connection effort is repeated for each partner
• 500 partners > 20 times first project cost
• Without leverage, this is not affordable (and largely unanticipated)
• Key: Let the trading partners do the majority of the effort.
