EERP Progress:Technology and Standards

Confusion of SOA

• Perfect in theory– To close the gap of IT system and business objectives, and ena

ble business people to participate the IT system design, and SOA also very fits in trend of servicialization.

• Difficult in implementation– What is the Service? How to define a Service when considering i

ts relationship to the business objectives.

• Different points of views– Currently SOA is promoted mainly by the vendors, they probably

intend to create another technology area, so that can ask their users to upgrade the existing IT systems 。

– We think SOA should be a revolution for users to solve their business program, rather than another design methodology for vendors 。

Users’ point of views

• Factors to achieve busines objectives ：– Business models– Human resource configuration– Knowledge structure– Partnership and allinaces– 。。。。。。

• Next generation of IT system ：– Directly support users’ business objectives– Consider both internal and external business resource

s– Evaluate the whole business process rather than a sin

gle point of function.

Difficulties of WS• Perfect in theory

– Intend to provide a standard interoperability, and standard system that supports the integration of any third party tools 。

• Difficult in practice– Because of the performance issues and the compatiblity among differen

t versions of WS standards, WS does not provide the better price/performance ratio in the tradition of data and application integration 。

• Different points of views– Currently the vendors seem mainly position WS as the alternative data/a

pplication middleware, and it could be a market strategy, the vendors haven’t fully utilized the interoperativity of third party applications.

– Should use WS for service interoperability, that integrates and exchanges the performance of services, in this way, WS can best exhibit its interoperability, while not to be required for the performance.

The view of services

• Description of services– Business quality of a service– The SLA and Rating of services– Service composition– 。。。。。

• Service integration– The aggregation of composite service QoS to form th

e business objectives.– End to end service QoS monitor and performance eva

luation.– ……

EERP

• A new system design methodology and a set of standards to support.

• SOA can best support the implementation of EERP– EERP system consists of services that can be evaluated, optimized and

replaced, …….

• WS standard can be adapted– Adoption of existing WS standards to support the interoperability of servi

ces ：• Adoption ： WSDL, WS-Policy, WS-TX• Extend ： WS-bQOS, WS-SLA, WS-Rating, ….

• Extend and adopt BPM technology– EERP-BPM

• Focus on the optimize the end to end business objectives– Directly support the business objective optimization.

EERP progress

• Business model investigation– From customer

• Close up the gap between IT terms and business objective terms;

• Lower the learning curve• Reduce the adoption barrier

– From vendors• How to introduce an application that deals with business

objectives,• how to stimulate the market demand, • how to overcome the possible long adoption period and

sales barrier.

EERP progress

• Technology R&D– For customers

• SaaS deployment, fewer clicks to result• Easy to lookup relevant service provider• Domain knowledge and industry vertical stat.

– For vendors• SOA/Webservice• Service QOS/Rating data generation (static, dyna

mic, …)• Service SLA implementation

EERP frame

• Characters of EERP ： On demand– Platform to support third party services– Dynamic identification of services– Flexible integration of services– Loosely coupled integration environment– Share of service resources with other EC service providers– Business collaboration support– Intelligent service composition– End to end collaboration– Optimization of business process– ….

EERP early adoption

• Customer acquisition– China Netcom EERP based Chemical eCom

merce service portal• Government funded• Changfeng member company, eBridgeChina, deve

loped the service portal• Launched Dec. 15, 2007• 20,000 chemical companies and service providers• Over 2000 usages of EERP process evaluation too

l.

EERP reference implementation

• EERP in chemical industry– Why choose chemical industry:

• Chemical industry typically is company clusters around a few major industry giants;

• Those industry giants usually are the producers, master distributors or key consumers of raw/basic materials, while the SME in these clusters conduct frequent business transactions with those giants ；

• The transportation, warehouse, and other logistic process may take a significant portion of transaction expense. The EERP can substantially reduce the over transaction expense by optimizing external service costs 。

Summary and Plan

• After three year’s R&D, promotion and sales marketing activities:– Completion of basic theory and relevant framework– Completion of the framework of some initial standards– Completion of two prototypes– Establish International collaboration force

• Focuses in 2008 ：– OASIS TC– Completion of three OASIS EERP standard drafts – Continue to push for large scale adoption
