Keynote I: DTTN - The E-commerce Platform
Justin Yue

Abstract
The HKSAR Government has initiated the establishment of the Digital Trade and Transportation Network (DTTN) with the vision of helping the overall competitiveness of Hong Kong through an open, neutral, secure, and reliable community e-platform that facilitates information flows amongst all parties involved in the supply chain. The DTTN acts as a catalyst to promote e-business adoption specifically by SMEs. It also provides an infrastructure that generates new business opportunities for the IT industry to develop software and value added services to be used in conjunction with the DTTN.

Keynote II: Digital Communities and Implication for e-Business
Josephine M. Cheng

Abstract
Humankind has always benefited from geographically co-located communities as it provides social values by allowing members to feel a sense of belonging, to share knowledge and to collaborate and innovate. In recent years, we have seen an explosion in the number and the diversity of digital communities, e.g. MySpace, SecondLife, Massively, and Multiplayer Online Games (MMOG). Enabled by emerging technologies such as social software and 3D internet, these digital communities are providing new forms of interactions that are important to individuals. In this talk, we examine characteristics of digital communities and their potential to provide value to the globally integrated enterprise. In particular, digital communities technologies such as tagging, blogs, wikis, reputation systems, social network analysis and virtual worlds can be leveraged in the enterprise to enable collaboration and learning, team building and interaction with customers and business partners. With the increased use of digital communities such as MySpace and SecondLife as venues for viral marketing, we will discuss the implication to the e-Business.

Keynote III: Proposition for E-DoD: An Overall Plan for Network-Centric Operation
Raymond A. Paul

Abstract
DoD currently has a crisis of software economics. As software becomes complex, our ability to design, develop, produce, distribute, and maintain software is being increasingly challenged. This crisis shows every sign of deepening in the future. What is required to address this crisis is a change of paradigm in the economics of software. This memo briefly outlines an emerging approach, called E-DOD. The E-DOD model is based on software as a service (SOAS) that is enabled by the rapid adoption by industry of the Internet and Web (I&W) technologies. The time is ripe for DoD to adopt this E-DOD model. The software industry emerged with the economic model of software as a product. The product is designed and produced in a "software factory," purchased by a client as part of a "change of ownership transaction," and shipped to the client on some media. Maintenance was originally based on shipping upgraded versions of the software to the client through the postal system. The I&W technologies have made it possible for the clients to control the entire distribution network by downloading software from sites maintained by vendors. This has seen the emergence of "software distribution aggregators" like Digital River (http://www.digitalriver.com) which handle the download, shipping, and payment for thousands of software vendors. The architectural principle behind E-DOD and SOAS is the "service oriented architecture (SOA)" that impacts the entire engineering cycle of software. New software applications are offered as a service on the network that meets the standards of security, reliability, availability, and scalability. Each service has a "definite range of behavior" that is published to all potential users and implemented according to their engineering decisions. This concept of "service level agreements (SLA)" also has significant business impact. In this open environment it is important to know what others have done, and other applications can be leveraged, rather than built anew. There are two kinds of users of a service in the E-DOD SOAS model. The "end user" implements the service, and "service developers" build new services with one or more existing services. End users' requirements are usability, human-machine interaction, performance, security, availability, etc. Service developers' requirements are based on the specific functions of a service and the potential to adapt to their own service. To address the needs of service developers, all service providers must publish a clear description of their offering through an application programming interface (API) or definition of service parameters in SLAs.

Biography

Keynote IV: Emergent Trends on Green Business and Service Engineering Green Business
Jen-Yao Chung

Abstract
Climate change, rising energy costs and resource constraints are increasing becoming global issues for government and business. These global issues are driving new trends in the development of Green Technologies. Renewable energy sources, advanced water management, efficient resource recycling, waste reduction, and intelligent utility networks are gaining strong interests and supports from both the public and private sectors. One of the key initiatives is the application of Green Technology to supply chain management. The objective of this green application is to reduce the carbon emission of company operations. In this talk, we will discuss the new wave of green business and the emerging services on green assessment, diagnosis and consulting, tools and modeling, manufacture process and re-design. We will also discuss the carbon disclosure project and the new emerging business in the carbon trading.

Keynote V: Accountable Services
Kwei-Jay Lin

Abstract
Accountability has been a major concern in the financial industry and public institutions, especially after ratification of the Sarbanes-Oxley Act of 2002. Service accountability means that a service deployed should impose an obligation or willingness to accept responsibility or to account for one's actions. For enterprise and public services, this is especially important in order to gain trust from their customers or support from their constituents. The main issues in providing accountable services are the transparency, accessibility, and fidelity of service execution traces, especially after some undesirable result is detected. In this talk, we will discuss the goal, the issues, and the technology to achieve accountability in service engineering.
