Abstract
IT systems are widely used in today's society, so project managers (PMs) in IT system development play an increasingly important and responsible role. In such projects, the qualifications required for PMs are not limited to project management skills, but also include the capability to lead a project to success even in the face of difficulties. Outstanding PMs are said to demonstrate common behavioral characteristics called PM competency. This paper discusses how to practice "dandori" as a means to increase PM competency. Dandori consists of practical know-how that includes recognizing the need to pay special attention to risk management. The paper explains that the concept and practice of "dandori" are effective in developing PMs and improving their discipline. As PMs repeat projects operations based on "dandori", this becomes a regular practice for them, improving their competency over time.
