Drivers for Business Systems (1/3)

• Industry boundaries are bluring.• ”OKO Bank acquires majority of Pohjola Insurance”

• “The insurance group Tapiola entered the banking industry on

Monday.”

• Companies are focusing on core business and

outsourcing many support functions.• “Elisa said that it would outsource some of its subscription handling

and invoicing operations.”

• “Stora Enso plans to outsource between 600 and 700 jobs at its

mills in Finland, including its cleaners and security guards.”

Drivers for Business Systems (2/3)• Business goes to information services and processes• “The Delta Nervous System processes 5 million business events each day, dealing with gate, fuel, food, and customer data. The ability to share this information with our employees and customers in real time, and to automate how we share it, has allowed us totransform our business, improve customer service, and reduce costs.” (Delta Airlines)

• "Close integration of manufacturers, service providers, operators and sales channels will enable us to decrease costs in the telecom industry and, at the same time, increase value by enabling business transformation through collaboration and the e-business support for new emerging business models“ (Nokia)

• “E-banking is one of the fastest growing as well as technically innovative groups at Nordea. Simultaneously, e-banking lowered expenses and further increased productivity.” (Nordea)


7

Drivers for Business Systems (3/3)

• Regulations, compliance and governance

requirements

• Basel II, HIPAA, Sarbanes-Oxley (SOX)

• Corporate governance

• B2B compliance and monitoring (e.g. RosettaNet)

• Auditing

• Data protection

• Digital rights management


8

Outcome

• Electronic business and service channels have

become vital in a global competition where.

• Flexible and integrated enterprise information

systems have become the foundation of market

leading enterprises.

• Requirements set by public authorities for business

compliance assurance and business process

governance are here to stay.

SOA and BPM manifesto

• Service-oriented architecture (SOA)

• Business applications are leveraged, integrated and

exposed as context independent composable

services.

• Business process logic is extracted from core

business applications and logic.

• Integration architecture is based on open

standards-based component technologies and

interfaces.


14

SOA and BPM manifesto

• Business process management (BPM)

• Business processes are made explicit and visible.

• Business process owners are identified.

• Business processes are discovered, designed,

integrated, deployed and optimized in evolutionary

manner.

• Business process models are managed in a digital

format that can be shared with IT professionals and

made executable straightforwardly.

17

Landscape of Standards

• BPMN

• BPEL

• WS-CDL

• BPDM

• Web services standards


18

Landscape of StandardsBPMN (Business Process Modeling Notation)

• A widely adopted graphical notation standard for

modelling business processes.

• Initially developed by BPMI.org (www.bpmi.org)

that formerly merged with OMG

• Home page for BPMN: http://www.bpmn.org

Landscape of StandardsBPMN example

From: http://www.bpmn.org/Documents/Mapping%20BPMN%20to%20BPEL%20Example.pdf


20

Landscape of StandardsBPEL (Business Process Execution Language for Web Services)

• An XML-based orchestration language for Web services specified

by OASIS.

• Current accepted version is 1.1. Version 2.0 in draft phase.

• Roots in IBM’s WSFL and Microsoft’s XLANG.

• Issues (v1.1)

• Distributed transactions

• Data transformations

• Choreographies

• Home page for BPEL: http://www.oasis-

open.org/committees/tc_home.php?wg_abbrev=wsbpel


21

Landscape of StandardsWS-CDL (Web Services Choreography Definition Language)

• Choreography definition language specified by W3C.

• Represents a shared public process between process

participants, specifying observable message exchange,

completion criteria and compensation policies.

• A choreography definition is a shared business agreement or

business protocol between multiple process participants.

• Specifies publicly observable behavior of its participants by

defining roles and possible interactions – message exchange

patterns – for them.

• Choreography should represent all essential events in the target

business process.

• Home page for WS-CDL: http://www.w3.org/2002/ws/chor/


22

MDA

Landscape of StandardsBPDM (Business Process Definition Metamodel)

• A metamodel that specifies business process constructs

and relationships in a language and technology

independent way.

• BPDM will be the profile of UML.

• Driven by OMG (EDS, IBM). Currently in draft phase.

25

SOA principles• Service context-independence – Services do not depend on the usage

context they are used.

• Service contract – Services adhere to a communications agreement, as defined collectively by one or more service description documents.

• Service loose coupling – Services maintain a relationship that minimizes dependencies and only requires that they maintain an awareness of each other.

• Service abstraction – Beyond what is described in the service contract, services hide logic from the outside world.

• Service composability – Collections of services can be coordinated and assembled to form composite services.

• Service autonomy – Services have control over the logic they encapsulate.

• Service statelessness – Services minimize retaining information specific to an activity.

• Service discoverability – Services are designed to be outwardly descriptive so that they can be found and assessed via availablediscovery mechanisms.

Impacts on IT professionals

• The role of IT as a company’s support function is at

the end of the road.

• IT departments will be evolved to process

management organizations that contains both IT

professionals and process analysts.

• Software and integration architects/developers need

to be trained on process and systems thinking.
