In this chapter, we discuss XML Web services, which integrates different systems and applications into one comprehensive system. XML Web services connects different entities such as corporations, governmental bodies, and nonprofit organizations, enabling the adaptive collaboration work (ACW) which is essential to promptly meet the increasingly diverse needs and kaleidoscopic changes in the economy. ACW is critical in the ubiquitous society where constant improvement of business processes and cooperation and collaboration with both existing and new systems are required. We propose the advanced application of XML Web services based on the ACW would enable a variety of organizations to collaborate with each other on the Internet and ultimately increase their productivity and efficiency. XML Web services effectively strengthens business management as it enables organizations to share personnel information across the board, therefore, organizations can unify management of their human resources. In the ubiquitous society, whether it is public or private, organizations need to develop and cultivate human resources capable of planning integrative strategy with information and communications technologies (ICT), designing and developing systems, managing hardware and software, and operating/maintaining systems.XML Web services based on the ACW gives suggestions on tactical solutions for these emerging agendas.
