WHAT IS ENTERPRISE ARCHITECTURE?

The Open Group defines ‘enterprise’ as follows:

▪ An enterprise’ is any collection of organizations that has a common set of goals and/or a single bottom line.

▪ In that sense, an enterprise can be a government agency, a whole corporation, a division of a corporation, a single department, or a chain of geographically distant organizations linked together by common ownership

The Open Group defines ‘architecture’ as follows;

▪ A formal description of a system, or a detailed plan of the system at component level to guide its implementation

▪ The structure of components, their inter-relationships, and the principles and guidelines governing their design and evolution over time

DO WE NEED AN INTEGRATED ARCHITECTURE?

… OH YES, WE DO!

Facts on Winchester Mystery House …

▪ 160 rooms, 2.500 m², 40 bed rooms, 47 fireplaces, 17 chimneys

▪ Construction started 1884 - 38 years to build - cost of $ 5.5M

▪ No plans, no architect (only Sarah Winchester as owner)

▪ 147 craftsmen worked 365/7/24

▪ Highly Talented participants, lot of High-Tech and innovation, 3 patents.

… but no architecture or overall concept:

▪ 13 Stairs to nowhere

▪ 65 doors that lead to blind walls

▪ admitted 24 roof windows in the floor

▪ a chimney begins in the basement, rises 4 floors

and ends 2 floors under the roofhttps://en.wikipedia.org/wiki/Winchester_Mystery_House

WHAT IS ENTERPRISE ARCHITECTURE FRAMEWORK?

An architecture framework is a foundational structure, or set of structures, which can be used for

developing a broad range of different architectures. It should describe a method for designing a

target state of the enterprise.

COMPANY STRATEGY: ELITE FORCES SUPPORTED BY A LARGE PLATFORM

Within the next 10 years, we will implement a strategy of

deploying elite forces with the support of a large platform,

and gradually separate resource management authority from

business management authority.

Y-MODEL

▪ Y-Model as the core of the EA representing the business architecture

▪ Unifiying all the different views and architectures into one holistic perspective

▪ Illustrating the connections between nearly each and every object throughout the company

The structure of the Y-Model

Left Arm

▪ Represting the logical order of the

functions, the so-called end-to-end

view (or project view)

Right Arm

▪ Represting the single isolated function

within one departmentTop

BottomBottom

▪ The trunk of the Y-Model

▪ Contains single components used to assemble

processes in the top parts

GUIDING PRINCIPLES

• No over-engineering.Simple

• No modelling for the modelling’s sake.Beneficial

• No silos.Integrated

• No re-invention of wheels.Reusable

• No visual overheads.Practical

• Not carved in stone.Extendable

• Not lost in detail.Abstract

Y-MODEL

• Functional view

The right hand side represents the

functional view on the processes.

Each department consists of

different functions each fulfilling its

own purpose, represented on

three levels of granularity.

• End2End View

The left hand side

represents the End2End

view of the enterprise

core processes organized

into three levels of

different granularity.

• Components

On level 4 to 6 the components are

shown, derived from the function building

the base for the End2End process.
