This paper describes our practical experiences in developing and
deploying a global delivery architecture throughout the IBM IT
(information technology) delivery organization. IT delivery has
been moving toward a globally integrated delivery operation, based
on global centers in places such as Bangalore and Shenzhen, for its
infrastructure outsourcing clients. This has presented many
challenges: some technical, some organizational, and many to do
with people and culture. We describe our architecture-based
approach to global integration. We give an outline of the Global
Delivery Architecture (GDA), which was specifically developed for
this environment. We describe the core technologies within GDA
that support this integration: the enterprise service bus, portals for
internal and client use, and knowledge and configuration
management. We also discuss the practical problems we
experienced in developing and deploying the architecture, covering
governance, organization, and cultural issues encountered as we
build up global capability. Finally, we discuss how the architecture
can be used at the individual client account level to enable a
particular environment to be tailored for local needs.
