Tracking United Parcel
Service Shipments
The Problem
Since 1907 United Parcel Service (UPS)
has been in the package distribution
business
It is the world’s largest package
distribution company, transporting over 3
billion parcels and documents each year
in over 200 countries.
© Prentice Hall 2004

Tracking United Parcel
Service Shipments (cont.)
UPS provides the means for customers to
track their shipments to determine the
status and whereabouts of a particular
package
In the past, this was done primarily over
the telephone
Customers would call UPS with the
tracking number of their shipment
© Prentice Hall 2004
7
Tracking United Parcel
Service Shipments (cont.)
An operator would look up the status of
the shipment in the UPS database and
relay the information to the customer
Servicing these calls cost an estimated $2
per call

Tracking United Parcel
Service Shipments (cont.)
The Solution
UPS created a Web site (ups.com) that
enabled customers to:
track their shipments online
determine the cost and transit time for
delivery of a package
schedule a package for pickup
locate the nearest drop-off facility
© Prentice Hall 2004
9
Tracking United Parcel
Service Shipments (cont.)
These online facilities are accessed from
the UPS homepage
The customer clicks the “Tracking” tab
at the top of the homepage
This takes the customer to an online
form where the customer simply enters
the tracking number and then hits the
“Track” button
The customer receives precise
information about the location of the
designated shipment

Tracking United Parcel
Service Shipments (cont.)
The front end of the UPS Web site is
simple, but the back-end processing
used to handle a tracking request is
more complicated
Requests are handed off to one of a
handful of Web servers
This server passes the request to the
appropriate application serve
© Prentice Hall 2004
11
Tracking United Parcel
Service Shipments (cont.)
The application server passes the request
to an IBM AS/400 computer attached to
the UPS tracking database (the largest
transaction database in the world—20
terabytes of data
The mainframe performs the database
search for the status information
Then it is passed back up the line
through the various servers to the
customer’s browser

17
The Development Process
Several options are available for
developing an EC site
The components making up a Web site
come from a small number of vendors or
from several different vendors
Small storefronts with a few key
components can be developed with
HTML, Java, or another programming
language

(ASP): A company that provides
business applications to users for a
small monthly fee
The cost of developing an EC site can
run in the thousands of dollars
© Prentice Hall 2004
19
The Development
Process (cont.)
To ensure success, a systematic
development process is needed to
create, implement, and maintain a site
A project team is also needed to
manage the development process and
the relationships with outside vendors
and business partners
The development process includes
four steps
© Prentice Hall 2004
20
The Development
Process (cont.)
Step 1: Creating an EC architecture
EC architecture: A plan for organizing
the underlying infrastructure and
applications of a site
© Prentice Hall 2004
21
The Development
Process (cont.)
The plan includes:
Business goals and vision for the site
Information and data required to fulfill
the goals and vision
Application modules that will deliver
and manage the information and data
Specific hardware and software on
which the application modules will run
Human resources and procedures for
implementing the architecture
© Prentice Hall 2004
22
The Development
Process (cont.)
Step 2: Selecting a development
option
EC applications can be:
developed in-house
outsourced to another party
some combination of both
© Prentice Hall 2004
23
The Development
Process (cont.)
An application built in-house can be built
entirely from scratch or commercial
products can be used and modified to
meet specific needs
An outsourced application can be run:
entirely by an ASP
on a third-party marketplace
on another company’s Web site
© Prentice Hall 2004
24
The Development
Process (cont.)
A company needs to participate in the
architectural design
At the end of this step, an application is
built (or purchased) and ready to be
installed
© Prentice Hall 2004
25
The Development
Process (cont.)
Step 3: Installing, testing, and
deploying EC applications
Connecting the application to back-end
databases, to other applications, and to
other Web sites
A series of tests is required
© Prentice Hall 2004
26
The Development
Process (cont.)
Unit testing: Testing application software
modules one at a time
Integration testing: Testing the combination of
application modules acting in concert
Usability testing: Testing the quality of the user’s
experience when interacting with a Web site
Acceptance testing: Determining whether a Web
site meets the original business objectives and
vision
© Prentice Hall 2004
27
The Development
Process (cont.)
Step 4: Operation and maintenance
A site is continually updated
new products need to be added to the
catalog
prices need to be changed
new promotions need to be run
These changes and updates undergo the
same testing procedures used during the
installation process
© Prentice Hall 2004
28
The Development
Process (cont.)
Usage patterns and performance need to
be studied to determine which parts of
the underlying applications should be
modified or eliminated from the site
