BPM versus BPMS

When to choose BPM

Overview of BPM system

Vision and caveat

BPM and process enabled SOA

Design implication for SOA architects

Conclusion

Introduction to BPM Business Process Reengineering (BPR) Emerged in the early 1990 – Michel Hammer & James Champy. Many of projects resulted in complete failure Resistance to change Lack of understanding of business model and underlying process Failure of nerve on the part of the client companies. Business Process Management (BPM) After 10 years from BPR. BPR  start from scratch BPM  build on and transform that which already exist [ incremental change and evolutionary optimization ]

Business Process Reengineering (BPR)

Emerged in the early 1990 – Michel Hammer & James Champy.

Many of projects resulted in complete failure

Resistance to change

Lack of understanding of business model and underlying process

Failure of nerve on the part of the client companies.

Business Process Management (BPM)

After 10 years from BPR.

BPR  start from scratch

BPM  build on and transform that which already exist [ incremental change and evolutionary optimization ]

BPM versus BPMS BPM ISO9000, Six sigma BPMS Technical platform for realizing BPM management initiatives. not limited the automatic execution of digital process model, but “encompasses the discover, design, and deployment of business processes as well as the executive,administrative, and supervisory control over them to ensure that they remain compliant with business object”

BPMS

Technical platform for realizing BPM management initiatives.

not limited the automatic execution of digital process model, but “encompasses the discover, design, and deployment of business processes as well as the executive,administrative, and supervisory control over them to ensure that they remain compliant with business object”

When to choose a BPMS Complexity and cost of BPM should be considered When to choose?  고려사항 IT and business must work hand-in-hand Business management in enterprise should be prepared together with IT organization to apply BPMS . [IT:BPMS, Business:6Sigma] Utilize process template Incremental process change from Business process template from BPM vendor can reduce risk Match the right technology to your problem Two key characteristic of business process is “complexity” and “frequency of change” Adopt the development model

Complexity and cost of BPM should be considered

When to choose?  고려사항

IT and business must work hand-in-hand

Business management in enterprise should be prepared together with IT organization to apply BPMS . [IT:BPMS, Business:6Sigma]

Utilize process template

Incremental process change from Business process template from BPM vendor can reduce risk

Match the right technology to your problem

Two key characteristic of business process is “complexity” and “frequency of change”

Adopt the development model

Overview of BPM System Modeling language Graphical modeling language – BPMN (Business Process Modeling Notation) Process modeling Language Define business process Enable the exchange of process definitions between different vendors BPEL4WS (Business Process Execution Language)  Developed by IBM & Microsoft BPML (Business Process Modeling Language)  Developed by BPMI.org and supported by SAP,SeeBeyond,Sun etc. BPMN

Modeling language

Graphical modeling language – BPMN (Business Process Modeling Notation)

Process modeling Language

Define business process

Enable the exchange of process definitions between different vendors

BPEL4WS (Business Process Execution Language)  Developed by IBM & Microsoft

BPML (Business Process Modeling Language)  Developed by BPMI.org and supported by SAP,SeeBeyond,Sun etc.

Overview of BPM System Architecture of BPM System Processes are modeled graphically – BPMN Process are stored in a blocked model  BPEL4WS,BPML Processes are executed by process engine

Architecture of BPM System

Processes are modeled graphically – BPMN

Process are stored in a blocked model  BPEL4WS,BPML

Processes are executed by process engine

Vision and caveat Vision Instead of application hard coding, BPM facilitates the modification,reconfiguration, and optimization of process definitions with graphical tools that can be used by less technology-oriented business analysis Caveat ?? Topology of Hub&Spoke and BPM The scope of BPM is limited to a single business unit Crossing the border of the organization requires distributed process control and largely heterogeneous standards

Vision

Instead of application hard coding, BPM facilitates the modification,reconfiguration, and optimization of process definitions with graphical tools that can be used by less technology-oriented business analysis

BPM and the Process-Enabled SOA PAST Data & Function  OOP  Distributed Object Limitation Fine grained Performance problem : Coarse grained (SOA) require less frequent interaction between client and server Reuse problem : Fine grained granularity has complex dependency. It reduce reusability.

PAST

Data & Function  OOP  Distributed Object

Limitation

Fine grained

Performance problem : Coarse grained (SOA) require less frequent interaction between client and server

Reuse problem : Fine grained granularity has complex dependency. It reduce reusability.

BPM and the Process-Enabled SOA Future (SOA) Past : Data and functionality Future : Core business logic & Process control logic  increasing agility Core business logic Comprise basic data access service,c o mplex caculation, and complex business rule. Orchestrated by BPM or process centric service Process control logic Orchestrate Core business logic

Future (SOA)

Past : Data and functionality

Future : Core business logic & Process control logic  increasing agility

Core business logic

Comprise basic data access service,c o mplex caculation, and complex business rule.

Orchestrated by BPM or process centric service

Process control logic

Orchestrate Core business logic
