The strategy is straight forward and very easy to understand. – IBM was the dominate seller of computers and
software.  Thousands of companies worldwide had IBM computers using SNA for their networks.  Thousands of other
companies had IBM computers or competing computers using other protocols for their networks. Those networks
didn't interconnect. --  When a customer of IBM needed support, the System Engineer (SE) or Program Support
Representative (PSR) would go to an IBM facility, do research and load a fix on a tape.  Then the SE or PSR would
drive to the customer location. – Since the information was initially in electronic form, it could be delivered
electronically if there were a connection between IBM and the customer.  – To establish that connections between
IBM and it’s customers was part A of Step 1.  – Many of IBM’s customers were also suppliers. Connecting suppliers is
part B of Step 1. – Connecting both customers and suppliers made Electronic Customer Support a two way E-
business solution. That was the beginning of the formal Electronic Customer Support Architecture and Strategy to
deliver wide scale e Business to Business communication. – Step 2, Once IBM’s customers and suppliers were
connected to a common network for e business with IBM, those same customers could use the same connection to
perform their own e business with their customers and suppliers. – Step two was a simple expansion of the IBM to
many to allow any to any. – The cost benefit work had been completed for communication with IBM.  The subsequent
Business to Business communication was virtually cost free productivity gain. – Step 3,  While step one and two
concentrated primarily on IBM and it’s customers and suppliers, step three went after other enterprises or smaller
enterprises who weren’t or might not be IBM customers or suppliers. A person who makes belts for a retailer might
have just a PC. Their e-business activity could also be conducted through the global network. – Step 4 consisted of
the end customer who is the general public who purchased anything from any company.  That leads to Step 5 which
is the ultimate goal to allow the architect (and you) to communicate with those who he does business with as well as
friends and family along with access to a myriad information sources, applications or users.

This approach could have been thought of by anyone in the Arpanet or pre-Internet teams.  They implemented fair
use rules to specifically exclude the any to any E-business that is characteristic of the ECS Architecture and Strategy
and the Internet we know today.
