From the literature, it is evident that there are various kinds of process models that are used by the software industries for the development of small, medium and long-term software projects, but many of them do not cover risk management. It is quite obvious that the improper selection of the software development process model leads to failure of the software products as it is time bound activity. In the present work, a new software development process model is proposed which covers the risks at any stage of the development of the software product. The model is named a Hemant-Vipin (HV) process model and may be helpful for the software industries for development of the efficient software products and timely delivery at the end of the client. The efficiency of the HV process model is observed by considering various kinds of factors like requirement clarity, user feedback, change agility, predictability, risk identification, practical implementation, customer satisfaction, incremental development, use of ready-made components, quick design, resource organization and many more and found through a case study that the presented approach covers many of parameters in comparison of the existing process models. .展开更多

The requirements designing—house of quality is designed to evaluate the maturity degree of the solution, and the evaluation results can help to manage and control the development process. Furthermore, a fuzzy evaluation method based on the minimum deviation is proposed to deal with the fuzzy information. The quantitative evaluation result of the maturity degree can be calculated by optimizing the semantic discount factor aim for the minimum deviation. Finally, this model is illustrated and analyzed by an example study of the aircraft collaborative design software.展开更多

It has two main objectives: to facilitate the understanding of concepts learned in theory and to facilitate the monitoring of SW projects that students develop. The system gives the teacher control and the students a guide on the activities that must be carried out throughout a software project development. QualiTeam is a tool conceived to help in the challenge of providing students with concrete examples with which they can practice and clarify the topics taught in the classroom. With it, students can apply concepts that, in the initial training of a software engineer, are generally taught only at a theoretical level such as: review process, change requests, trouble reports, document version control and testing documentation management. QualiTeam is free and available online. It has been in operation for 5 years, through which improvements have been made until achieving a quite stable version.展开更多

Developers may have a hard time knowing what could happen to the software when making changes. To support the developer in reducing the uncertainty of the impact on the software run behavior due to changes in the source code, this paper presents a tool called IMPEX which analyzes the differences in the source code and differences on the run behavior of two subsequent software versions, in the entire repository, demonstrating to the developer the impact that a change in the source code has had on the software run, over the whole software history. This impact helps the developers in knowing what is affected during execution due to their changes in the source code. This study verifies that the software runs that are most impacted by a given change in the source code, have higher chances in being impacted in the future whenever this part of the code is changed again. The approach taken in this paper was able to precisely predict what would be impacted on the software execution when a change in the source code was made in 70% of the cases.展开更多

However, the quality requirements analysis is a very difficult matter because it is non-formulaic and demands much of product customer’s technical perceptiveness. Traditionally, analysis of quality requirements of a product has been conducted through questionnaires or interviews with customers based on survey investigator’s personal experience. This kind of lack of structure and incompleteness in the traditional approach introduced missing requirements and errors in prioritizing requirements to implement in the requirement analysis of a product. On the other hand, we have been working on developing the techniques (SQuaRE) for quality requirements and evaluation for system and software product for a long time in ISO/IECJTC1/SC7WG 6. For the purpose of specify the quality requirement of system product, the method of quantitative quality requirement definitions based on ISO/IEC9126 [1] quality model that includes six characteristics is widely recognized. However, independency among each quality characteristic is not sure and the suitability of method by using these six quality characteristics for quality requirement is not certified statistically. In this paper, we propose the concept of quality requirements definition method based on the SQuaRE quality models define in ISO/IEC25030 [2,3]. Also, this paper proposes the result of verification about effectiveness of quantitative quality requirement definition approach from the view point of six quality characteristics described in ISO/IEC9126.展开更多
