4. Organization vs Enterprise
the organisation is a legal structure,
primarily conceptual/physical in
nature, defined by rules,
roles and responsibilities
– the organisation does – it
provides action, ‘how?‘
the enterprise is a social structure,
primarily emotive/aspirational in
nature, defined by vision,
values and mutual commitments
– the enterprise is – it
provides motivation, ‘why?‘

5. Enterprise Application?
Can you define?

6. Enterprise Application
EA: is a business application
Complex, Scalable, Distributed, Component based
Mission-critical
Used on different platforms
Data centric & user friendly
Stringent on Security and administration
Hundred requirements must be satisfy
difficult to understand or predict
6

7. The Story
At the beginning : Data processing focus.
• Collect the data (financial, numeric, statistical)
On the way: Functional focus
• Calculate the salary, bonuses, incomes
• Create invoices, generate reports
• HR problems resolve (Resource management)
• Logistical/Provisional problems resolve (ERP)
At the end: Process Focus
• Enhance the business efficiency (BPM)
• Predict more accurate the Income/Outcome (BPO)
• Smart and fast decisions (BI)

17. What we integrate?
17

18. What is a integration?
 In engineering, system integration is the
bringing together of the
component subsystems into one system and
ensuring that the subsystems function together
as a system.
 In information technology, systems
integration is the process of linking together
different computing systems and software
applications physically or functionally, to act as a
coordinated whole.
http://en.wikipedia.org/wiki/System_integration
18

19. But the EAI?
Enterprise application integration is an integration framework composed of a collection of
technologies and services which form a middleware to enable integration of systems and
applications across the enterprise.
 lack of communicatios
 Inefficiencies
 identical data are stored in multiple locations
 unautomatizable processes
 Existence of information silos
 Inefficient business processes
19

20. Why we need EAI?
Purpose
 Data integration  Transaction management
 Process integration  Security management
 Vendor independence  Multiple Technology
 Common Façade
Benefits
 Real time information access
 Streamlines business processes
 Integrity across multiple systems

29. The benefits (Myths)
Operational: Managerial
•Productivity increase •Better control/ overview
•Cost savings •Better and fast decisions
•Data consistency, Data access •Automations on decisions
•Focus on Process •Performance evaluation (KPI)
•Workflows /Automations •VISIBILITY
Strategic IT
•Long term planning (more companies can be integrated) •Control
•Knowledge sharing •Scalability, Maintainability
•Past, Present, Future information's (BI) •Data transparency
•Real Time data access
•Standardize and organize systems and data
•Robustness, High availability
Organizational
•Less work /more efficiency
•Better reaction to market changes
•Focus on Business
•New oportunities
29

30. The truth (Reality)
Financial problems Pitfalls
• 2002 : 70% of EAI project failed • Missing integration strategy
• 2003 : 25-30% of IT budget is allocated for EAI • Combine EAI with other
• HIGH COST on start, slow and invisible benefits project
Added value problems • Lack of recognition that EAI is
an architecture
• Lot of companies follow the trend, not the business
• Long term running projects, no added values
• Neglecting security,
performance and
• CONSTANT CHANGES –Never ending stories
monitoring;
Make organization efficient Internal politics
• The EAI doesn’t reduce the complexity • poor communication
• Competing standard, doesn’t applied
Knowledge
• Loss of details /focus point (Why we need this?)
• Lot of DESIGN/ARCHITECTURAL/NEGOTIOTION TIME
• Lack of specialist
• Lack of managerial knowledge
30

31. Technical Reality
 Multiple interfaces give flexibility / irreplaceability ?
 Different applications can re-use the interfaces?.
 Services exposed over web can be easily decoupled.
 The IT/SW/HW doesn’t resolve the business problems.
 Lack of software response to
 Inconsistent data structure is transferred as a NORMALIZED?
 EAI helps a better reusability? Maybe freezing the interface. One
Scope / One interface ?
 Knowledge on BUSINESS side affects the technical implementation
 Lack of ANALYSIS (business & system)
 Lack of feasibility analysis & risk analysis.
31

32. TIPS: Aks! Ask! Ask!
 SCOPE of EAI? Why do you what to do this?
 Why this EAI add value and how can materialize in COST (for ROI calculation)?
 How many applications do I need to integrate?
 Will I need to add additional applications in the future?
 How many communication protocols will I need to use?
 Do you what to maintain the old systems? Why?
 Infrastructure, locations, peoples who access?
 How important is scalability to organization?
 Security?
 Critical factor? What is you uptime?
 Process/Workflows : Do my integration needs include routing, forking, or aggregation?
 Does my integration situation require asynchronous messaging, publish/consume messaging models, or
other complex multi-application messaging scenarios?
 Decision makings: BI/ data aggregation, data collection, modelling?
32

33. The Future
 Cloud Migration / Integration
 Cloud & Premise Integration
 Enterprise Social Networking Integrations
 Focus on Business Process
 Focus on:
– Human centric Proces
– Document Managent
– Comprehensive integration (integrate the twitter with facebook
and CRM and financial systems)
 Collaborations between Enterprise in real time.

34. BPM? Time to change …
2003 : Smith
and Fingar
Business Process
Management
(BPM): The Third
Wave

35. Quotes
“Nature laughs at the difficulties of integration.”
Pierre-Simon Laplace
“A goal without a plan is just a wish.”
Antoine de Saint-Exupéry
“Vision without execution is hallucination.”
Thomas A. Edison .
