Abstract
In order to improve project quality and to prevent project failure, NTT DATA has been implementing risk assessment process. Sector PMOs implement risk assessment to prevent project failure. Since quality improvement is essential for an efficient risk assessment process, not only the assessor's ability but also cooperation of the project is required. PMOs aim to "establish and improve risk assessment processes and procedures" with emphasis on "assuring a swift and reliable assessment process" and "delivering clear and acceptable assessment." This paper presents our approaches to risk assessment process improvement (visual control and sharing of process through process standardization) and future tasks.
