The solution to these challenges: Enterprise Architecture

An ‘Architecture’ is [IEEE-1471]:

the fundamental organization of a system embodied in its components, their relationships to each other and to the environment and the principles guiding its design and evolution.

‘Doing Enterprise Architecture’ (EA) means

actively organizing the components of an enterprise and the relationships between those components and the environment, keeping a number of principles in mind. Doing Enterprise Architecture entails the creation of architectural descriptions.

Architectural descriptions

a collection of products to document an architecture.

Conclusions

Companies within an Extended Enterprise need to coordinate their Web services development efforts.

They can use Enterprise Architecture to achieve the necessary coordination.

At the K.U.Leuven (SAP-leerstoel Extended Enterprise Infrastructures)

we are developing guidelines to realize the IT-enabled Extended Enterprise.
