Software defects cost time and money to diagnose and fix. Consequently, developers use a variety of techniques to avoid introducing defects into their systems. However, these techniques have costs of their own; the benefit of using a technique must outweigh the cost of applying it. In this paper we investigate the costs and benefits of automated regression testing in practice. Specifically, we ...

Financing demands for the increasing number of large-scale build–own–operate–transfer (BOOT) hydropower projects in Nepal have necessitated greater mobilization foreign investment. International investors and lenders perceive significant exchange (FoREX) risk when investing such projects. In various developing countries, FoREX risk-allocation mechanisms offered by public sector allocate risks t...

The application of information and communication technology (ICT) in the architecture, engineering and construction (AEC) sector has evolved over several years. Organisations continue to invest in ICT in their bid to harness technology and streamline business processes. However, construction organisations continue to experience perennial problems that militate against successful implementation ...

While many successful and well-known open source projects produce output of high quality, a general assessment of this development paradigm is still missing. In this paper, an online community of both small and large, successful and failed projects and their programmers is analysed mainly using the version-control data of each project, also according to their productivity and estimation of expe...

California hospital construction projects are large, complex, and extremely difficult projects to execute and navigate successfully. One of the primary reasons for this is the OSHPD permit, review, and inspection process. The quality control rigor imposed by this third party inspection procedure has caused great angst amongst most general contractors and subcontractors. This study examined over...

The value of information technology has been proved to be related to alignment between business and information systems (IS). However the constant report of failed IT projects suggests a misalignment between business and IS at the implementation stage. The majority of alignment assessment approaches focuses on the strategic level and overlooks the connections with IT projects. Although research...

S oftware is constantly evolv ing, and its effect on business operations and daily life continues to grow. It’s hard to imagine a day without using your cell phone, browsing the Internet, sending an email, watching TV, or using other IT products and services. Today, most human activities and organizational businesses depend heavily on software. Unfortunately, software failures happen across man...

Hydroelectric projects are often pursued on the promise of economic development and environmental co-benefits as a source low-carbon energy. We analyse case Muskrat Falls hydropower mega-project (located in Labrador, Canada) to understand why this project failed live up its promised benefits, but instead delivered double disaster cost risk. The key concepts anti-reflexivity deep stories help us...

From observations ga!hered during a study of large software development projects, it was concluded that the so&are engineering technology (SET) transfm process is plagued with problems involving learning, technical communication, and negotiation. The underlying causes of these problems are discussed. The observations presented here attempted to help facilitate the MCC Software Technology Progra...

background and importance: pseudomeningocele is a rare complication of spine surgery, and it is the collection of cerebrospinal fluid in paraspinal tissues. giant pseudomeningoceles are still rare, and very few cases have been reported in literature. it is usually occult in presentation, and patients do not have any symptoms ascribable to it. case presentation: we came across two symptomatic pa...
