According to some prealable unformal
questionnaire – you want to know

What is EA ? What are EA concepts ?
What is EA for ?
Is it not yet another buzzword ?
Is it not yet another marketing artefact to sale
licences, books, trainnings, and consulting ?
Is it really with an added value ? Within the
modelling life cycle ? If yes how to position it ?
How to compare EA with other modelling
methods and frameworks ?

Enterprise
Architecture

Motivation behind EA
EA has been firstly thought to address two problems (in 1987) :
System complexity : organisations were spending enormous
budgets in IT

Poor business alignement : organisations were finding it more
difficult to keep IT systems alignes with business model

Basically enterprise are looking for more agility, high profils,
lower risk, more satisfied senior management, and
More cost and less value problem recognised 23 years ago, but
have today reached a crisis point.
Roger Sessions, CTO of ObjectWatch©

Kind of real problems EA is
supposed to answer to

Enterprise Architecture – definition 1
for A. Goel et al., EA is a
holistic expression (of the enterprise)
in terms ofkey strategies usually evolving from different domains of(i)
business architecture (business strategy, processes, services,
structure, policies and governance), (ii) information architecture
(ontologies, taxonomies, meta-data, master data, transaction data,
information flows and other forms of data and information assets related
to the enterprise), and (iii) technology architecture (infrastructure,
security, applications, technology services and middleware), 2009.

With regards to
enterprise
Functions, Data,
Roles & Units,
Expression Events,
EA EA Ressources,
Produits & services,
etc.

K. Baïna & S. Slimani 2010 ©

M. Lankhorst defines EA as
a coherent whole of principles, methods, & models
that are used in the design & realization of an enterprise’s
(i) organizational structure, (ii) business processes, (iii)
information systems, and (iv) infrastructure, 2005.

EAF Concepts, Principles and
methodology
EA dimensions
Concepts :
Enterprise views or perspectives : function (activity),
information, resource, organisation unit, role, behaviour
(business process), etc.
modelling constructs (ie documents, and reports, aka
artefacts)
flows : Materials, Information and Control

Principles
Separating enterprise behaviours from functions
Separating enterprise behaviours from resources
Separating enterprise resources from roles & organisation
units

EAF - Enterprise Architecture
Frameworks
An EAF is proposal of a reference architecture
or structure for Enterprise Architecture (like an
Enterprise Architect toolkit)

Main EAFs
1. Zachman Framework (Zachman Institute of
Architecture)
2. TOGAF (The Open Group Architecture Framwork)
3. FEA (Federal Enterprise Architecture, US White
House)

Many other EAFs
1. US Government Frameworks (DoDAF (US Department of
Defence), MoDAF (UK Ministry of Defence), TEAF (US
Department of Commerce), CEAF (US White House), EA Cube
(Scott Bernard), CIMOSA, GERAM (ISO 15704 2000), GRAI,
PERA, RM-ODP (ISO/IEC 10746), etc.

TOGAF (used mainly for its ADM method)
For TOGAF, divides an architecture into 4
categories :

TOGAF ADM (Architecture
Development Method)

FEA (use mainly because of its most complete framework)

Complies with the Clinger-Cohen Act
Provides a common methodology for IT acquisition

Papers Impact : ENSIAS R&D prototyping, and case study results, published in RCIS’2007 and then in
ICEIS’2007 could influence and drive a huge BPM research community (many researchers in many well
known universities, and many international conference & journal papers) : (i) to be more attracted by
BPM open source benchmarking within a such large open source community, and (ii) to focus later on
(instead of being lost within a such fertile production) only on the top 3 WFE : jBPM, OpenWFE &
Enhydra Shark with newer visions, and interests both profitable for BPM open source community and
BPM research.

Who was Alqualsadi ?
First name : Abou Al Hassan ibn Ali ibn Muhammad
Surname : al-Qalasadi a.k.a. : Al-Qalsadi, Al-Qalasadi, Al-Kalsadi
birth : on 1412, Bastah, (north of Granada) AlAndalous (current Andalusia)
death : on 1486, Béja, Ifriqiya (current Tunisia)
expertise : Arithmetics, Algebra, Astronomy
contribution
Transforming language (numbers values, operations, & relations) to meta-language (symbolic
arithmetic variables with symbolic operations and relations in arabic alphabet lexicon)
Abreviation of Variable Names to Symbols (long equations algorithms become shorter & easier)
unknown X is born : ‫ ش‬is the abbreviation of shay that will be translated in italian later as « causa » and then will be abreviated
to X
Abstraction and symbolisation of arithmetic operations
examples
3 9 means √ 9 = 3
Lexical meta-language
36 ‫ 6 م ل‬means 62 = 36
27 ‫ 3 ك ل‬means 33 = 27
becomes = latin alphabet
126 ‫ 6 م و 3 ك ف 2 ل‬means (62 + 33) × 2 = 126
‫ ش ج ش‬means (√x) 2 = x
application to formalisation and resolution of algorithms of algebric (polynomial, diophantine)
equations
some of his arithmetic vulgarisation books
« Raising the veil of the science of the letters’ dust » (kashf alasrar aan ilmi hurufi alghubar)(alghubar means
« dust » and here stands for written arithmetic with numerals.
« Clarification of the science of arithmetic »(al-tabsira fi‘ilm al-hisab)
well known for his pedagogical approach
no prerequisites assumption is done (to be able to target beginner level), clear and direct style,
avoiding complex demonstrations, exposing only practical methods, style clair et direct, a huge
number of exercises, many illustrations of arithmetic algorithm rules

Who was Alqualsadi ?
is the origin of, among others, visual symbolic
representation of the square root (‫ )ج ذ ر‬Alqualsadi
abreviated to (‫ )ج‬so it gives :

9 9 9
becomes becomes

Please notice visual similarities !

see. Solomon Gandz, On the Origin of the Term "Root", The American Mathematical Monthly,
Vol. 35, No. 2 (Feb., 1928), Mathematical Association of America

Example of Alqualsadi symbolic abreviations
in algebra Applications : Pythagorean
Algebric Proof
Concrete Language Abstract Meta-Language

(A+B)2 = A2 + 2*(A*B) + B2

Algebric proof of the
Pythagorean theorem,
by symbolic quadratic equations

Geometric proof of the
Pythagorean theorem, (A+B)2 = C2 + 2*(A*B)
by Pythagoras

A2 + 2*(A*B) + B2 = C2 + 2*(A*B)

Thus: A2 + B2 = C2 q.e.d.
