ABSTRACT

Business intelligence (BI) technologies have received much attention from both academics and practitioners, and the emerging field of business analytics (BA) is beginning to generate academic research. However, the impact of BI and the relative importance of BA on corporate performance management (CPM) have not yet been investigated. To address this gap, we modeled a CPM framework based on the Integrative model of IT business value and on information processing theory. Data were collected from a global survey of senior managers in 337 companies. Findings suggest that the more effective the BI implementation, the more effective the CPM-related planning and analytic practices. BI effectiveness is strongly related to BA, planning and to measurement. In contrast, BA effectiveness is strongly related to planning but less so to measurement. The study suggests that although both BI and BA contribute to corporate management practices, the information needs are different based on the level of uncertainty versus ambiguity characteristic of the management practice.  相似文献

The increasing demand for software project managers in industry requires strategies for the development of the management-related knowledge and skills of the current and future software workforce. Although several approaches help teach the required skills in a university setting, few empirical studies are currently available to characterize and compare their effects. This paper presents results of an externally replicated controlled experiment that evaluates the learning effectiveness of using a process simulation model for educating computer science students in software project management. While the experimental group applies a system dynamics (SD) simulation model, the control group uses the well-known COCOMO model as a predictive tool for project planning. The results of the empirical study indicate that students using the simulation model gain a better understanding about typical behavior patterns of software development projects. The combination of the results from the initial experiment and the replication corroborates this finding. Additional analysis shows that the observed effect can mainly be attributed to the use of the simulation model in combination with a web-based role-play scenario. This finding is strongly supported by information gathered from the debriefing questionnaires of subjects in the experimental group. They consistently rated the simulation-based role-play scenario as a very useful approach for learning about issues in software project management.  相似文献

The purpose of this paper is to investigate leadership effectiveness in IT-centered organizations giving attention to gender and levels of management. A seven-point scale instrument that measures leadership effectiveness (leading organization, leading people, leading self) was used to collect data. The participants (N = 197) were top, middle, and lower-level managers that used IT for organizations’ strategic, tactical, and operational activities. Collected data were analyzed using MANOVA. Results indicated no overall significant group differences for the levels of management with respect to the three leadership effectiveness groups. However, there were overall significant group differences for gender and the interaction of gender and levels of management. In all three leadership effectiveness groups (leading organization, leading people, leading self), women leaders scored significantly higher than men leaders did. Women also significantly scored higher on all levels of management than men did with respect to the three leadership effectiveness groups. These findings are interpreted, and implications are discussed.  相似文献

Insufficient knowledge of how the working environment (WE) impacts company performance leads to a poor basis for managerial decision making. The objective of this study was to survey and evaluate available tools relating WE to business results. Nine tools were identified and qualitatively evaluated using 11 criteria. The tools were clustered into three categories, ranging from analysis of WE risks as well as calculation of their economic impact to solely investment analysis. Shortcomings in the tools include insufficient attention to quality and productivity issues and insufficient guidance for users. Although further methodological development is indicated, researchers should also attend to the factors affecting tool uptake and application as well as the potential to integrate such analysis into companies' regular accounting systems. © 2011 Wiley Periodicals, Inc.  相似文献

This article aims to offer an alternative method to analyse technology acceptance models, namely a segment‐wise analysis. The empirical illustration of this method involves data that were collected during a company‐wide implementation of a Sales Force Automation technology in Europe. The data comprise a variety of commonly used technology‐related, context‐related, and person‐related variables. The segmentation procedure, which involved a finite mixture partial least squares estimation, provides more insight into the different ways in which people come to accept new technologies. Unlike other segmentation studies published in IS journals, the resulting segments are based on similarities and differences in the structure of the underlying theoretical models rather than (a collection of) individual variables. Further research or a re‐analysis of existing data should help establish robust “technology acceptance model”‐based segments as well as comprehensive profiles of the individuals in each segment.  相似文献

Replication in distributed computing systems provides improved availability and reliability in the event of site failure and network partitioning. However, if strict mutual consistency is required, transactions can be processed in at most one partition, thereby reducing availability. We present a consistency control algorithm that relaxes strict mutual consistency criteria, and allows concurrent processing in all partitions. Inconsistency of data objects in different partitions is resolved at the time of merging the partitions when recovery occurs. The basis of our algorithm is a new merge mechanism that utilizes available semantic information about the data objects and transaction types. We present a formal proof of correctness of the algorithm. Results from a simulation model show that our algorithm performs better than a previously proposed approach that uses compensating transactions to sacrifice serializability of replicated data.  相似文献

Most work related to quality of service (QoS) is concerned with individual system components, such as the operating system or the network. However, to support distributed multimedia applications, the entire distributed system must participate in providing the guaranteed performance levels. In recognition of this, a number of QoS architectures have been proposed to provide QoS guarantees. The mechanisms and schemes proposed by those architectures are used in a rather static manner since the involved entities, e.g., the network, sender and receiver, are known before the connection (call) set-up phase. In contrast to these architectures, we propose a general QoS management framework which supports the dynamic choice of a configuration of system components to support the QoS requirements for the user of a specific application. We consider different possible system configurations and select the most appropriate one depending on the desired QoS and the available resources. In this paper we present an overview of this general framework; especially, we concentrate on QoS negotiation and adaptation mechanisms. To show the feasibility of this approach, we designed and implemented a QoS manager for distributed multimedia presentational applications, such as news-on-demand. The negotiation and adaptation mechanisms which are supported by the QoS manager are specializations of the general framework. The proposed framework allows to improve the utilization of system resources, and thus to increase the system availability; it also allows to recover automatically, if this is possible, from QoS degradations. Furthermore, it provides the flexibility to incorporate different resource reservation schemes and scheduling policies, and to accommodate new system component technologies.  相似文献
