This paper investigates the applicability of Use Case Point estimation model to global software project development. Nowadays, there is growing trend among leading software companies to outsource their project geographically, in countries with lower labor rate. This new trend increases competitiveness in the software market, which in turn shortens the development lifecycle time. This leads to several...
Many IT change initiatives involving the development of software fail, and the scale of the failures can be large. We believe that the traditional contract model for software development is generally responsible for these failures. Even if an IT project is resourced internally, the organisation applies similar management practices to the IT project as if it were outsourced to a third party supplier...
This survey deals with the problem of evaluating the submissions to crowd sourcing websites on which data is increasing rapidly in both volume and complexity. Usually expert committees are installed to rate submissions, select winners and adjust monetary rewards. Thus, with an increasing number of submissions, this process is getting more complex, time-consuming and hence expensive. In this paper...
Tag collision arbitration for the multiple tags is a significant issue for fast identification. This paper proposes a tree-based backoff (TBB) protocol to reduce the number of the iterations implemented in the procedure of the tag collision arbitration. Compared with traditional tree-based protocol, simulated results show that the TBB protocol reduces the computational complexity efficiently by employing...
Concept of Internet of Things has been proposed by professor Ashton from MIT Auto-ID for the first time, EAN and UCC established a none-profit organization EPCglobal, a lot of standards established to make the relative application canonical, aims to raise visibility in supply chains by enabling interested parties to query item-level data. EPCglobal defines EPC-IS, EPC-ONS, DTD, DTS etc. in its architecture...
Enterprises in the industrial sector of large-scale plant engineering are currently experiencing an extremely high level of competitive pressure. In order to stay profitable in the long run different approaches are suggested. The approach to increase the efficiency of a company during the project execution of turnkey plants, which is pursued in the present paper, refers to the establishment of process...
Drawing on the diffusion of innovation (DOI) theory as well as on the emerging literature on RFID technology, this study explores a set of technological, organizational and environmental characteristics that will play an important role in the RFID adoption decision process within the Saudi retail industry. Results of data collected among seven (7) Saudi large-scale retailers are presented and discussed,...
There are different concepts of what complex systems are, and as a result, there are also many approaches for how to define and measure their complexity. The current paper argues that the very representation of a system can indicate what its complexity is, and how to measure it. The paper represents systems from a communication perspective. From this perspective, a system interacting with its environment...
During the last years, companies are developing a growing interest in improving the efficiency and quality of their internal business processes. The need of reuse of some business part to fulfill compagnie's requirements leads to the need of extracting business fragments from business process model. The aim of this paper is to propose an approach for identifying business fragments from business process...
Researchers and practitioners have employed various analytical and empirical examinations of financial data in their attempts to detect fraud. Nonetheless, despite the various comprehensive analytical examinations and other supporting techniques, there are still fraud incidences that are not discovered. There have been scarce research works that examine the readability of qualitative text in company...
Global Software Development projects could be best understood as intrinsically complex adaptive living systems: they can not purely be considered as 'designed systems', as deliberate design/ control episodes and processes (using 'software engineering' models) are intermixed with emergent change episodes and processes (that may perhaps be explained by models). Therefore the evolution of GSD projects...
In the light of globalization it is not uncommon that different teams from different locations get involved in the development of a software product during its evolution. However, empirical evidence that demonstrates the effect of changing team members on software quality is scarce. In this paper, we investigate quality of a software product, across subsequent software releases, that was first developed...
Cities serious about achieving sustainability need to consider what the role of information might be for them, while acknowledging their municipalities as being more complex than the sum of the physical infrastructure. This paper argues that predicting the future is not a useful mechanism for city planning, and claims that this can actually be disruptive to sustainability because adaptability, differentiation...
Learning curve has been known as a method to describe the learning capability of an organization. This paper will investigate the impact of learning to assembly line capacity. A case study has been conducted in one of major car manufacturers in Indonesia. It produces variants of products and implements a mixed model assembly line. The purposes of this research are to identify the learning curve model...
Smart Grid software applications are a kind of ultra-large-scale system (ULSS) where complexity has a profound impact on their quality and defect profiles. Their complexity also adds challenges to the process of designing studies to investigate their complicated software development. In this paper we propose an empirical research agenda to study the relationship between the characteristics of Smart...
The influences of project environment and leadership style on team performance are examined in a field study of 74 technology-based project teams. The findings provide insight into the business processes, organizational conditions and managerial leadership style most conducive to high project performance in complex and technology-based team environments. One of the most striking finding is the large...
Current guidance for the USA's defense acquisition processes have been formalized in the Joint Capabilities Integration and Development System (JCIDS). The enhanced requirements from these policies and procedures have made system of systems (SoS) acquisitions more difficult as defense agencies try to implement the updated practices. Many of the associated challenges are a result of the fundamental...
This paper presents a maximum power point tracking (MPPT) method based on fuzzy logic theory. A comparative study of conventional fuzzy methods is carried out and advantages and disadvantages of each one are explained. Additionally, different situations that may cause a fuzzy logic control (FLC) system fail to track or degrade in performance are analyzed. Accordingly, the theory and concept of a new...
Businesses are increasingly engaging in inter-organizational collaboration. At the same time, assessing the benefits and the success of an inter-organizational system is still a challenge. Academia and businesses alike struggle with insufficient assessment methods and benefits measurement processes. Our research applies and extends a recently developed framework for the assessment of expected and...
This paper takes the recent example of a European company's efforts to develop a global electrical safety program tailored to the wind industry. In order to get top management buy-in, three components are demonstrated to be essential. First, the complexity of a comprehensive global electrical safety program will create great confusion unless there is a clear focus on the two most basic safe work practices:...
