for

IT

have

changed?

In

the

past

enterprise

architecture

was

designed

for

known

use

cases

and

integrations

–

The

consumer

changed

the

way

business

users

view

IT

products

and

processes?

Today’s

enterprise

must

architect

for

the

unknown

–

Enterprise

IT

systems

are

no

longer

an

island

and

must

build

their

capacity

to

integrate

with

the

outside

world?
