IT Software Project Risk Management Research Based On The Relations Of Risk

When the world entered the information age, technology, software development tools have made great progress, software industry has become the fastest growing industry, the national development influence. During 90 time, global software production value of average annual growth rate has been maintained at 15-20%, the software industry has become the biggest industry in the world. In recently officially released 2011 blue book" Chinese informatization situation analysis and forecast (2011)" pointed out that, in 2010 China software business income 133,64 billion yuan, grow 31% compared to the same period, industrial scale is enlarged 22 times 2000, with an average annual growth rate of about 36%. In the global share rose from less than 5% to 15%. Software industry employees from less than 300 thousand to more than 2 million people. Software information products in most of the knowledge intensive and the core competitiveness of the part, is the core of informatization work and premise to enhance national competitiveness, is of great significance. With software increasingly complex and large, software development and management are increasingly complex, software risk also increases. Especially in the IT software project development, often need to use many new, complex technology, invest huge amounts of funds, organize a huge R & D team, as well as a long development cycle. All these will bring a wide variety of unforeseeable uncertainty or risk, ultimately leading to the failure of the project. According to the world bank, a statistical data shows that, in developing countries the government information systems project, 85% above are not successful. IT software project development and management has been the existence of various uncertainty, serious impact on the smooth delivery of the project.IT software project risk management is increasingly valued by people, become the field of software engineering to ensure the smooth implementation of the project and ensure software quality indispensable key link. Strengthen the IT risk management of software project management in software development is one of the most important jobs. According to the United States of America Microsoft quantitative studies show that, in the management of risk investment 5% workload can be increased by 50%-75% of the timely delivery of possibility. Visible risk management in IT software development and project management important degree.In this paper, through the study of IT software project risk management theory and the present situation, will be both qualitative and quantitative research, according to IT software project risk to make objective and scientific analysis and evaluation, the analysis and comparison of domestic and foreign classical risk management theory and model study based on the results, a prospective presents the application of principal component analysis method for the identification of risk factors and risk analysis of the relationship between the link between and the introduction of IT software project risk management process, focusing on the IT software project requirement analysis stage of the risk identification, risk analysis, risk management strategy and risk control risk management process is discussed, by using the principal component analysis and correlation analysis of IT software project risk factors identification and analysis, system of establish a set of operational risk based relationship of IT software project risk management method.
