Fujitsu's system development methodology: SDAS

Recent information systems have become critical infrastructures for both industry and society, and there are growing requirements for higher quality and reliability and a shorter development period to meet ongoing changes in the business environment. To meet these needs, Fujitsu has strengthened and enhanced its system development methodology called System Development Architecture & Support facilities (SDAS). Also, Fujitsu has adapted WAS to new technologies and expanded its scope to cover the complete lifecycle of systems in Japan, from analysis and development to maintenance and rebuilding of existing customer systems. WAS provides a development methodology, framework, and tools for improving quality and reducing the time needed for development. WAS features an accurate definition of requirements, a high degree of expandability and maintainability by using a mission-critical application framework, and effective development tools to automate testing and documentation. This paper outlines the features of WAS methodology, its framework, and development tools.
