36 Guah（ASP商业模型中的重要问题）

As indicated in this chapter and elsewhere in this book, the significant problems in the ASP business model are the information deficiency（缺乏） and asymmetry（不对等） between the business participants. It is also difficult for each participant to exchange information products and services in an efficient manner, and to partner in an intelligent enterprise. The social nature of knowledge sharing—especially critical business knowledge—carries high complexity. The capability advertisement and knowledge discovery, upon which agent-based approach to ASP depends, can only be achieved by message interaction among dynamic processes. Knowledge or service relevance is one basis for such approach to be introduced to real-life business procedure and service contracting in the 21st century by companies.
