Abstract This paper presents the results of a replication construct measurement perceived usefulness and ease use. extends work recent research which examined these constructs through structural equation modeling. uses new data set for two different technologies in conducting measurement. The use this are quite consistent with reported minor variations. Perceived usefulness, not use, is determinant predicted future usage.

Recently, Bayesian probabilistic models have been used for predicting software development effort. One of the reasons interest in use models, when compared to traditional point forecast estimation is that provide tools risk and allow decision-makers combine historical data with subjective expert estimates. In this paper, we a network model illustrate how belief updating procedure can be incorporate decision-making risks. We develop causal from literature and, using set 33 real-world...

Nearly all information technology educators and practitioners are familiar with the concept of a systems development life cycle (SDLC). The SDLC model is mainly based on new software development. stages vary methodology, but mostly include planning requirements definition, analysis, design system, implementation, post-implementation support such as maintenance security. Less explored known involved in commercial off shelf installation. actual implementation ERP (enterprise resource planning)...

Purpose Regardless of the diverse research on big data analytics (BDA) across different supply chains, little attention has been paid to exploit this information service chains. The healthcare where chain operations consume second highest expenditures, have not completely attained potential gains from analytics. So, paper explores challenges BDA at various levels Design/methodology/approach Drawing resource-based view (RBV), organizational and operational level nodes in To demonstrate links...

The widely discussed scientific data deluge creates a need to computationally scale out eScience applications beyond the local desktop and cope with variable loads over time. Cloud computing offers scalable, economic, on-demand model well matched these needs. Yet cloud gaps that must be crossed move existing science cloud. In this article, we propose Generic Worker framework deploy invoke in minimal user effort predictable cost-effective performance. Our addresses three distinct challenges...

Provenance that captures e-Science activity has long term value only if the right amount and kind of information is collected. In this paper, we propose a two-layer model for representing provenance capable both execution higher level process details.

:Integrated computer-aided software engineering (ICASE) tools and their effect on development effort productivity have gained interest in recent research. This research studies the applicability of function points technical complexity factor as estimators for ICASE projects. In addition, three factors—ICASE tool type, systems method, experience—on is studied. ICASE-based projects from Texas Instruments Electronic Data Systems were used this empirical Function accounted 74 to 82 percent...

A number of frameworks have been proposed to study the competitive use information systems. While these help in choice systems provide strategic use, approval and funding depends solely on business justification value applications as perceived by top management. The perception (PSVIS) management is conceptualized ii) an operational support type, a managerial productivity enhancement iii) decision aid type. An instrument was developed validated measure PSVIS. associated with good reliability,...

Introduction The success of system development is most often gauged by three primary indicators: the number days deviation from scheduled delivery date, percentage proposed budget, and meeting needs client users. Tools techniques to help perform well along these dimensions abound in practice research. However, project view systems should be broader than any particular tool or methodology. Any given philosophy approach can inserted into a best fit conditions, product, talent, goals markets...

Drawing upon the Organizational Information Processing theory principles, this study delves into impact of explorative and exploitative artificial intelligence (AI) capabilities on supply chain (SC) performance, specifically regarding efficiency resilience. A cross-sectional descriptive through survey leverages structural equation modeling data gathered from 267 distributor firms to test proposed model. Results indicate that Explorative AI have a positive SC resilience, but they do not...

Enterprise Resource Planning (ERP) systems are a growing area of research in business information systems. The primary purpose this was to test the effect ERP implementation on users. We used and performance stage model studied issues related adaptation, acceptance, routinization stages. An exploratory case study conducted these issues. consisted survey interview 25 employees at one organization. results provide data analysis findings from qualitative interview. point positive user climate...

Accurate software effort estimation is crucial for consulting organizations to stay competitive in their development costs and retain customers. Artificial Neural Network (ANN) an effective tool obtain accurate estimates. In this paper, models using ensembles regression analysis are developed based on data collected from 163 projects. The main emphasis of the paper developing experimental design achieve superior results. addition, we compare ANNs multiple analysis. We found two interesting...

Abstract The field of data ethics is concerned with the ethical considerations surrounding data, algorithms, and associated practices, aim identifying solutions. application principles to handling practices can facilitate identification delineation quandaries within domain science. present study focuses on topic ethics, specifically pertaining processes collection, model construction, evaluation, deployment. This introduces a comprehensive framework designed management in science projects....

<span>Outsourcing is the contracting out of all or part a companys information systems functions to outside parties. This research provides preliminary findings on perceptions IS (Information Systems) professionals outsourcing. The this study indicate that in order effectively deal with human aspects outsourcing, management must understand what exist within employee ranks and develop plan which addresses needs perceptions.
