Case Study An IT Transformation at Dell: An Oracle Enterprise
Architecture

ong known as one of the world’s largest manufacturers of personal computers, Dell
has grown into not only a multinational hardware and infrastructure provider but
Lalso an IT services and solutions provider as well. Rapid growth led to regionally
specific expansion from country to country. Dell ended up with unique manufacturing
facilities, regional order management systems, and different operating processes and
systems throughout the world.

Rhonda Gass, Dell’s Vice President of IT Strategy, Technology & Governance, is charged
with mapping out a future direction for the IT giant, with a three-year roadmap driven by
Dell’s Enterprise Architecture (EA) team. At an enterprise level this roadmap includes ten
major programs, each of which involves investments in the tens of millions of dollars—
and, in some cases, hundreds of millions of dollars. Some examples of these programs
include: Global Quote to Cash, Global Service Delivery, Solution Selling, Global
Manufacturing Execution, and Recurring and Usage based transactions.
Oracle is providing executive guidance for this transformative journey, working closely
with Gass and her enterprise architects to establish a long-term view of the requisite
processes, systems and technologies. Individual projects are undertaken to build general-
purpose capabilities, not merely to fulfill immediate needs.
