Abstract
Compared with development of the operating system of the former project construction (it is henceforth called SI project) of the unified type system which consists of two or more operating systems, an operating side, an organization side, and a period become large-scale, and many risks hang around development. What does the risk of a project generate as a cause when? You discover. How should you cope with it? The point of the risk management for leading SI project to a success is considered from a real failure project.
