A Research On Risk Evaluation Methods Of Software Project

In this paper, a thorough research on risk evaluation methods and applications of project lifecycle management for software projects from the viewpoint of project leads is carried out, which is based on project risk management theory and combining with features about software developing.The main clue of this paper is procedure of risk management. According to the features about risk evaluation process, common and practical methods and tools for risk identification, measurement, assessment and techniques are introduced; With reference to relative knowledge, some new models and new methods within each step of risk evaluation process are raised; These methods and models are illustrated with real project cases.The new methods and models given out in this paper are as follows:(1) TCQR, the quantification standard set of risk evaluation based on PMBOK. The framework is a two-tier model about risk factors and risk-driven factors. In TCQR, a risk-amplified modulus that reflects the capacity of management is involved in. So TCQR can reflect the features of software project better.(2) TBQ tool and standard set of quantification. The TBQ questionnaire makes risk identification and assessment of competence of organization more easier, and guarantees the feasibility of TCQR model.(3) Improved two-tier fuzzy evaluation method with the function of risk integration evaluation, and involved project risk modulus that reflects the general risk level of project.(4) Using success degree to evaluate the effect of risk management, and introduce some manners which risk evaluation methods can be used in software developing.The methods given above are as easy as possible for using andpopularizing in practice. This paper aims at supplying a standard, systemic and measurable method system on risk analysis, handling and decision-making for project leaders, and it also aims at providing a basic work for farther research in software project risk management fields.
