The nine parts of project management are classified into content type and objective type, whose mutual relation is expressed in chart. Meanwhile, based on the characteristics of engineering project management, supplement content about technical management is described. Content-type management is defined according to the functions and contents of technical management. Technical management is an important part in project management, because it is a starting point for objective-type management and the basis for content-type management.
