IBM's project management methodology has also undergone a process of development. In the process of transition from product to the service, IBM incorporated a variety of internal project management methods, such as application project development methodology, ERP Software implementation methodology, integrated products development methodology and so on, in the mid-90s, IBM launched a WSDDM methodology, that methodology actually consists of many different project management methodologies, crossing project management and technical methods together. In the late '90s, IBM established a Project Management Committee (PM / COE, Project Management Best Practice Center), integrating IBM's all project management methodologies, and built up a unified internal project management methodology, called WWPMM.WWPMM consists of four components: Project Management Domain, Project Management Work Product, Project Management Working Pattern, and Project Management System. In which, Project Management Domain can be understood as project management knowledge areas, it is similar with 9 major knowledge areas in PMBOK, but it also extended the content of PMBOK in the depth and breadth, to meet IBM’s unique characteristics and management philosophy.
