Outline Challenges for enterprises

Change of business environment Shift of SOA

EERP concept EERP key issues

QoS Service granularity Standards to be researched on Reference implementation EERP design&deployment strategy

EERP integration platform EERP Promotion and Implementation

Change of business environment business environment is tougher than

ever: Demanding customers

Shorter time and lower cost; Intense competition

Subject to frequent changes at technology and business process

new regulation Trade barriers and regulation.

Globalization Have to deal with partners across the world

Change of business environment

Companies want to: maximize their business results Revenues up Sustaining profits up Costs down

Profit growth becomes critical Sustaining profit growth is a key core

competence.

State of the enterprise

Operational Costs Consume IT Budgets ~70% of IT budget spent on sustaining and running

existing systems, only ~30% on new capabilities Enterprises typically want to spend ~45% on new

capabilities

Crisis of Complexity No “green-field” development New applications must integrate with

existing heterogeneous “legacy” systems

IT Must Deliver Business Agility Support new business opportunities Leverage new technologies

Changes in IT Architecture…

Shareholders ask for better IT utilization and greater ROI

Re-Use of IT assets and Integration of historically separate systems

Merger and acquisition have become a fact of life Integration of systems of different enterprises

New systems must be developed with (current or future) heterogeneity in mind

Always prepare for integration. Internet everywhere has created a set of new business models

Innovative business models may aggregate resources across the Internet world.

Shift to SOA

What is a "Service" ? A reusable business process or business function that can

be accessed through the standard web technologies Why?

Business to Business processes drive organizations – not IT

Better colaboration with Businesses Implications

Re-factor existing systems extracting correct business services

Shift to SOA

Exposing business partners as services that are: loosely coupled standards based, message driven, published and discoverable, and QoS measurable.

Shift to SOA

Data, logic and infrastructure accessed by routing XML-based messages (Web Service) throughout Internet

Location is meaningless Multiples Services suppliers Ubiquitous computing Preserves and connects existing systems Using the Right Software Architecture brings

exponential productivity gains

SOA in Action (example)

Next step of SOA How to coordinate services internal and

external to meet certain business objectives ?

How to achieve better business model for a enterprise?

How to form an end to end business process automatically and intelligently?

The answer is Service Oriented Resource Planning (SORP)






EERP concept: resource planning

With SOA and open standard, we can now help enterprises to improve their profits and sustain the profits, we introduce:

SORP: Service oriented resource planning SORP can optimize resources inside or outside of a enterp

rise, for example: SO-SCM

Optimize the resources of a enterprise and its suppliers. SO-CRM

Optimize the resources of a enterprise and its sales/mareking partners or its customers.

EERP: End to end resource planning, optimize the resources along an s

pecified value chain.

What does EERP do?

What is it? A new way to look at enterprise IT application

Integration inside and outside of a enterprise border. A new software architecture and platform

a collection of Web Services that perform various enterprise functions, data exchange, process integration, collaboration and other relevant work.

A self-healing, intelligent, and reliable service choreograph platform (SoftGrid)

EERP: basis

•Based on Web Services to link up applications in a “loosely-coupled” manner

•“Software as Services” and decouple environments and systems

•Eventually

•More robust

•Cost effective to develop

•Infinitely more flexible

EERP briefing

How does it work? Vendors base on EERP principle to develop next generat

ion enterprise application; SaaS for enterprise application Backend platform to support flexible service choreograph Service management

Enterprises use EERP to manage all relevant resources to achieve specific operation objectives.

Value chain integration Dynamic decision support Integration with eCommerce / online marketplace

Introduction to EERP

EERP is one of the most important practices of Service oriented resource planning.

EERP consulting services Help enterprises understand the operation objectives from 36

0 degree of their specific value chains. EERP toolkit

Value chain decomposition, service identfication, service choreograph and integration.

EERP implementation Different deployment strategies, could be either SOE or true

SOE implementation with third party service integration. EERP QOS management

Model, protocol to precisely manage QOS along the value chain to achieve end to end QOS assurance.

EERP: the possible killer app on SOA

SOA vs. past technology It directly maps business to the IT implementation, so it solves

today’s enterprise’s big problems (fast changing world); It enables the enterprise IT application integrate with almost

every partners’ services, and run on a much broad and heterogeneous network environment.

EERP vs. past IT application It tells the whole story of the enterprise performance and

operation. It ties enterprise operation with the market dynamics

EERP: manufacture(1/2)

Reference implementation A furniture manufacturer.

Value chain identification Service-lization: SCM, ERP, CPM (channal partner managemen

t), eMarektplace (Alibaba, furniture.com.cn and many other relevant eCommerce portals)

Service choreograph guideline (direct sales, channel sales, rental instead of sales and so on.)

EERP decision support console Batch and then real time interaction with all operational systems

EERP: manufacture(2/2)

Results: Identify the key revenue / profit bottlenecks and reveal the

dynamic pattern of those bottlenecks. Demonstrate the revenue / profit strong correlation with market

environment, even with the stock prices of certain key related companies.

Prove concept: the cost of manufacture is no longer a key problem for today’s manufacturers, instead the resources outside of the company command the revenue and profit.

Help company to completely change its business to furniture lease and customized furniture manufacture.

EERP: eGovernment(1/2)

Reference implementation GSP (government service platform)

20 government processes selected Objectives identified as: fast throughput, tighter contr

ol, accuracy, policy impact and correlation with central government policy.

200+ eGovernment applications are converted to WebServices.

Modified ESB to a GSP (SOAP + WSDL + BPEL)

EERP: eGovernment(2/2)

Early results: Help government customer to understand the G-B,

G-P dynamics. Identify the bottleneck of policy implementation

and rule adoption. Identify which crowd has a better access to the

government services. Help innovation in the process reform and

organization simplification.

EERP: consumers(1/2)

Reference implementation Best career planning service for college graduates

10 career paths selected 300+ career develop related services identified (employee

services, training services, marriage services, real estate agency, travel services…)

UDDI setup for career related service management Drag/draw to define the career paths, and selection of

personal objectives (key words: Fast path to rich, pleasant family life, entrepreneur, and so on).

Could be a very good online personal career service portal.

EERP: consumers(2/2)

Results: Very sticky online service for students. Now can compare different career paths for “the

most efficient way” to achieve goals Identified the college education importance is less

than 10% for certain career objectives Identified early marriages are vital for certain career

objectives Help government office to review the career training

policy.






EERP: QoS

Services are: able to measure; able to map to a business practice; may consist of services; able to test independently; able to observe the state change Security, access control

EERP: Quality of Service Service Classification QoS Classification QoS Requirements QoS Measurement and Evaluation QoS Control

Service Classification Service classification is the basis of t

he QoS definition Service can be classified on the basi

s of : Application envirement (Transportation,

communication, energy, ...) Objective ( QoS requirement (Time sensitive, cost

sensitive, …)

QoS Classification Quality level

Based on customer sense: Excellent, good, normal, not too bad, bad)

Based on quality data gathering: 1~10 grades

QoS types Time Cost Convenient…

QoS Requirements EERP QoS parameters definition

Response time Cost Complexity Convenient….

EERP QoS Requirements Excellent quality (range of time, cost ,…) Normal quality (range of time, cost ,…) Bad quality (range of time, cost ,…)

Quality requirements depart One service can be provided

on basis of the other service or sub-services , so the qualities of others may determine its quality.

The quality requirements of one service must be departed to a series of sub quality requirement based on its formed sub service.

QoS can be defined as several layers.

There is a mapping relation between upper layer QoS and lower layer.

Service A QoS Req

Sub Service A1 QoS Req

Quality assessment can be multi-objective:

Cost/time/accuracy/…… or any combination of them






EERP: Service granularity

Three types of service according its semantic meaning:

Fine granularity service Medium granularity service Coarse granularity service

EERP: Service granularity granularity effects service re-usability greatly

Aim of Optimization To reduce un-stable factors within coarse

granularity services as much as possible, utilize superiority of re-use coarse services, to improve re-user efficiency.


Granularity: how to measure Amount of computation the service afford granularity can be calculated by the business

process the service implements, namely, count of the code lines in the source code of the service.

Generally it’s difficult to measure service granularity accurately.
