| Abstract | Failures in software projects are a prominent factor in the approach taken by the software engineering community and much has been done for the success of such projects; however, there will always be risks. Increasing rates of success in software projects represent a significant challenge for the industry in which some risks (e.g., schedule delays, increased costs) may lead to failure in projects. In this context, the area of risk management has a significant importance. However, the lack of a process in risk management combined with deficient estimates of cost and time are some of the major causes of failures in software development projects. The risk management contributes positively to the reduction and control of the risks in the software project through its identification and quantification. Various techniques were proposed to evaluate the effects of such undesirable problems, but probability estimates are generally neglected, thus affecting the proper assessment of the risks. Therefore, the impact of risk on the performance of a software project is an important aspect that should not be overlooked. This paper proposes a methodology and models of dependability and performability for probabilistic assessment of development risks in software projects. In this methodology, the risk assessment is performed by using reliability block diagrams and stochastic Petri nets. Two case studies demonstrate the feasibility of the proposed technique. With the application of the methodology and proposed models, it is possible to verify the impact and assess the performability of development risks in software projects. Furthermore, this methodology allows the assessment of other development risks, as well as the performability evaluation in other stages of the software development process. All this can be used by software project managers to assess the impact of risks on different projects. |
