Software testing is a key process that ensures a reliable quality product, and like other activities in the development process, have a wide range of tools available, but still requires a lot of human work, where the final quality of the software can be impacted directly by several factors. In this sense, this study aims to identify the human factors (cognitive, operational and organizational) present...
Demonstrating software reliability across multiple software revisions has become essential to end users of an end point detection system used in the semiconductor industry. This would enable them to make informed decisions of upgrading software versions without making significant impact to their current established processes. We show how one can use standard defect data normally collected in any software...
High Reliability Organizations (HROs) operate in risky and safety-critical environments where failure avoidance overrides cost efficiency and other traditional performance measures. Research on military, air traffic control, and similar domains has identified five key HRO characteristics: preoccupation with failure, reluctance to simplify interpretations, sensitivity to operations, commitment to resilience,...
There are large, medium, and small enterprises which develop software projects that can be influenced by a risk. Identifying risk is first step of perfectly assessing and controlling risks in a project. In the literature, a lot of researchers identified risk factors in software projects but none of these can be generalized as base of risk factors in the software projects as they differ in time, culture,...
Agile software development is known by focusing on interaction among team members to share knowledge. However, little guidance is provided to encourage interaction across agile teams. Based on a preliminary conceptual model, this paper examines influencing factors, such as organizational strategy, and communication flow and channels, regarding inter-team knowledge sharing (KS) effectiveness in agile...
This article presents the results of an industrial study about the reliability of expert judgment in cost estimation in a medium-sized software company. The purpose of the study was to assess current practices within the company, and to use the results as a catalyst for improving the company's cost estimation processes. The study included the analysis of two aspects: variability and calibration. First,...
The estimation of effort is at the heart of project tasks, since it is used for many purposes such as cost estimation, budgeting, monitoring, project planning, control and software investments. Researchers analyze problems of the estimation, propose new models and use new techniques to improve estimation accuracy. However, effort estimation problem is not only computational but also a managerial problem...
Once, long time ago, there was a very old dinosaur living on the planet Earth. Big yet invisible to most, living in the dark places full of cold, dust and cables; surrounded by several groups of faithful - very specialized software teams, the only ones who truly understood him. But the life on the planet Earth had never been steady and recently spinning faster and faster around, so it happen that...
With the business development of large enterprise groups, the collaborative office platform has many administrative, business, work flow processing system, these flow systems respectively issue discrete tasks, there is no a unified task tracking and evaluation method. This paper put forward a multi task tracking evaluation model (MTEM) based on group Enterprise Collaborative Office Platform (ECOP),...
Consumer device is a newly coined term which refers to a new category of industrial products used by end users including automobiles, service robots, consumer electronics and smart houses. Unlike traditional industrial machineries, consumer devices are used in diverse, open, and dynamic environments. Furthermore, as accountability of manufacturing companies becomes crucial, they need to assure that...
We proposed a new approach for target value sequencing problem using weighted evidence theory. Target value evaluation index system is constructed located at artillery battlefield, the uncertain target information are fused based on the evidence theory, the index weight is decided based on analytic network process. The case proves the reliability of the results and the validity of this method. This...
Based on the Muncy-Vitell Consumer Ethics Scale (CES), this study develops a Chinese version of CES. Three dimensions are added, they are (1) consumer hegemony, (2) uncivil or discourteous acts in public and (3) drawing upon public funds or resources for personal consumption. The study also compares the present scale with the previous ones. Results show that 'passively benefiting acts' were considered...
Abstract-On the basis of previous literature, we propose five dimensions of relationship quality in information technology outsourcing (ITO): trust, effective communication, commitment, interdependence and harmonious conflict resolution; then we build a theoretical model of relationship quality, knowledge sharing and outsourcing performance, and propose some hypotheses about them. To test these hypotheses,...
We established a conceptual model of the association between cultural difference, knowledge sharing, relationship quality, and performance in IT-based service outsourcing, posed some hypotheses. In the survey that we conducted in the companies specialized in IT-based service outsourcing in Xi'an Software Park, we collected 170 valid answered questionnaires from the employees who involve in the outsourcing...
Research on globally distributed software development (GSD) assumes the characteristics of the GSD projects to differ from collocated projects. Results of mainly qualitative studies describe communication, coordination, and issues related to team dynamics as typical problems in GSD projects. However, there is a lack of quantitative studies using real project data, and proven research instruments and...
In this paper, optimal placement of distributed generations has been studied accurately. A proper objective function is proposed for distribution network losses reduction and improvement of reliability indices,. A 20 kV sample network, 114 buses from Azarbaijan (Tabriz) Power Electric Distribution Company is selected and different simulation has been performed by using DIgSILENT software. Simulation...
A review is carried out on how quantitative approaches have been applied so far to the Reliability Prediction and Assessment (RPA) for computer and communication systems. A series of the reliability evaluation technology based on analytic models and computer simulations are developed for use in product design and test, shape, system operation and maintenance, during a research initiative towards understanding...
Globalization, tougher competition and increasing customer expectations have led many organizations to adopt enterprise resource planning systems (ERP). However, organizations are beginning to realize the real impacts of ERP systems can be less than expected and that there is a need to better utilize ERP systems. This has led to greater focus on improved configuration and implementation. An important...
Trustworthiness is a crucial characteristic when it comes to evaluating any product, even more so for open source software, which is now becoming widely used. The authors conducted a survey to identify the reasons and motivations that lead software companies to adopt or reject open source software; they then ranked, according to importance, the specific trust factors used when selecting an open source...
Large number of scientific publications and press releases demonstrate that organizations are adopting the Scrum software development method with success in almost all areas. Nevertheless, traditional Scrum method is not sufficient for managing work in Network Organizations where Third Party Service providers may know nothing about the Scrum. This paper describes the findings of a field study that...
