Software risk management is the practice of assessing and controlling risks that affects the software projects, process or products. Those who practice risk management agreed that it is must be performed regularly throughout the lifecycle of a software system. But one of the main challenges in dealing with software risks is to provide a visual risk assessment tool. This paper intends to report on the visualization tool development based on a traditional software development process model -"Waterfall Model". This paper also shows the proposed framework and structured approach for this tool. The objective of this research is to construct a visualization tool for software risk assessment for all phases in software development processes.

“…We develop a Markov model to determine scenarios risk factors using components and connector risk factors. This model provides exact closed form solutions for the scenarios risk factors, while the algorithm for traversal of the component dependency graphs used in [31] [30] based on the methodology presented in this paper. The paper is organized as follows: Section 2 describes the well-known cardiac pacemaker system and presents its UML specification based on the use case diagrams and sequence diagrams.…”

Abstract-Risk assessment is an essential part in managing software development. Performing risk assessment during the early development phases enhances resource allocation decisions. In order to improve the software development process and the quality of software products, we need to be able to build risk analysis models based on data that can be collected early in the development process. These models will help identify the high-risk components and connectors of the product architecture, so that remedial actions may be taken in order to control and optimize the development process and improve the quality of the product. In this paper, we present a risk assessment methodology which can be used in the early phases of the software life cycle. We use the Unified Modeling Language (UML) and commercial modeling environment Rational Rose Real Time (RoseRT) to obtain UML model statistics. First, for each component and connector in software architecture, a dynamic heuristic risk factor is obtained and severity is assessed based on hazard analysis. Then, a Markov model is constructed to obtain scenarios risk factors. The risk factors of use cases and the overall system risk factor are estimated using the scenarios risk factors. Within our methodology, we also identify critical components and connectors that would require careful analysis, design, implementation, and more testing effort. The risk assessment methodology is applied on a pacemaker case study.

“…Since the methodology is entirely analytical and provides a closed form solution, it is very suitable for sensitivity analysis and automation. In fact, a prototype of the risk assessment tool written in JAVA which reads the embedded UML information from Rational Rose, and calculates the various risk factors has already been developed (see chapter 9) [Wang, 2003].…”

“…Figure 6.1 describes the use case model of the risk assessment methodology. To automate this risk assessment methodology the UML model is implemented as a prototype tool and is described in chapter 8 [Wang, 2003]. The use case model of the proposed methodology is described as follows: Figure 6.1 Overall Use Case UML model of the proposed methodology…”

Many companies develop and maintain different types of large-scale software systems for public and financial institutions. Should a failure occur in one of these systems, the impact would be enormous. It is therefore essential, in maintaining a system's quality, to identify any defects early on in the development process in order to prevent the occurrence of failures. However, testing all modules of large-scale systems to identify defects can be very expensive. There is therefore a need for methodologies and tools that support software engineers in identifying the defected and complex software components early on in the development process. Accurate early estimates will help v TABLE OF CONTENTS
