Globalization
Globalization is the development of an increasingly integrated global economy marked especially by free trade, free flow of capital, and the tapping of cheaper foreign labor markets
Economies of scale
$5,000 500
$10,000 2500
Per unit price $10
Per unit price $4
Assuming up-front costs are the same, the more we buy the cheaper it becomes
Thus the potential for profit rises
Cloud services and technology

CASE STUDY
Global enterprise decision to move to a global services stance
Consolidation of email is the primary driver
Secondary aspects include “anywhere access”
Decision to go with Google Apps ◦Email plus Drive, Sites, social media (G+)
Estimated 8.5M – 10M email servers worldwide
New technology drives ionnovation
Significant shift for a major global enterprise
Normally, business drives technology; but in this case a technology change will drive business change◦Promote collaboration◦Increase in efficiency
What was the justification?
Business justification in the form of◦Greatly reduced licensing costs
$2M - $3M/year◦Consolidation/reduction of hardware
Shift the infrastructure to the cloud (IaaS)◦New functionality for the same money
Collaboration Apps◦Global consolidated platform
Every OpCo now operates the service the same way
How was it implemented?
A project plan was created to move each OpCo to the new services
The plan included the pre-communications, the training, the implementation and post-implementation phases
Total plan was a 2-3 year migrationNorth America was the most aggressive,
moving nearly 8500 users to the new systems in 2 “big bangs” over 2 weekends
Problems & challenges
One size does not fit allIT users are used to a level of customization
that is not available; global controls which options are available to all
Tools which integrated with the old email system were incompatible with the new one
Some OpCos are very resistant to the change
During the migration, different OpCos using different email systems
More technology changes
Voice Over IP
We also made the move away from a traditional phone system to a network based phone system called Voice Over Internet Protocol (VoIP)
Traditional PSTN
Calls are limited by the number of lines available
Internet/Network based
Calls limited to the amount of bandwidth the network can route
Many things to consider
Basic Features
Call center/Advanced
All different ways to connect
PSTN
SIP
Enterprise PBX more complicated
Head Office, Branch Office, Remote Office all appear to be using the same extensions
4 or 5 digit dialing to any extension within the PBX, regardless of location
Call centers are worse yet!
VoIP reduces the overhead…and leverages the LAN or WAN networks as well as the Internet
Challenges
The enterprise has 420 sites between US and Canada
Several call centers in various countries & locations
Some very remote sites do not have good or stable internet connections
Requires a lot of upgrades/changes to infrastucture
Project has experienced weather delays, vendor delays, technology glitches
