2.5 How IT supports the transformation

"When we began construction of the data warehouse, we realized we

needed to arbitrate needs and prioritize business requirements, because

there is never enough money to do everything that everyone wants. So we

needed a plan that would help us combine agility with strong governance

for our data warehouse environment."

Yann Decre, business intelligence director and chief data officer for

Bouygues Telecom, from Teradata Magazine Q3/2010

The transformation process is also an IT and investment issue. Given the

complexity of IT specifications, the high impact of the transformation on the

whole organization and the long time horizon, the success of implementa-

tion is far from a foregone conclusion.

In our experience, projects often fail because project management is inap-

propriate and the implementation challenges are underestimated. Choosing

the right system support is crucial for the transformation success. We recom-

mend selecting a strong partner with a clear vision, a centralized approach

and strong execution capabilities. Companies need state-of-the-art systems,

i.e. an enterprise data warehouse, to solve issues with data silos, incompat-

ible interfaces and consistencies. Figure 6 contrasts a typical legacy system

structure with the data warehouse solution after implementation.
