Where does informatics fit in health care organizations?

Why is medical informatics important to health care leaders? As an emerging science, informatics focuses on applying computing and communication technology to decision making for clinicians and managers. It enhances the understanding of how information and communication systems can impact the work health care managers must accomplish. As the cost of technology for digital information management continues to decline, organizations and individuals will look for ways to offset the human costs of managing and conveying information. The way of the paper medical record is being replaced by the less expensive and more efficient digital information systems. Leaders of health care organizations need to look for every opportunity to deploy networks and computers to reduce the labor costs of data collection, storage, retrieval, and analysis.     

How Software Project Risk Affects Project Performance: An Investigation of the Dimensions of Risk and an Exploratory Model*

To reduce the high failure rate of software projects, managers need better tools to assess and manage software project risk. In order to create such tools, however, information systems researchers must first develop a better understanding of the dimensions of software project risk and how they can affect project performance. Progress in this area has been hindered by: (1) a lack of validated instruments for measuring software project risk that tap into the dimensions of risk that are seen as important by software project managers, and (2) a lack of theory to explain the linkages between various dimensions of software project risk and project performance. In this study, six dimensions of software project risk were identified and reliable and valid measures were developed for each. Guided by sociotechnical systems theory, an exploratory model was developed and tested. The results show that social subsystem risk influences technical subsystem risk, which, in turn, influences the level of project management risk, and ultimately, project performance. The implications of these findings for research and practice are discussed.     

The Role of Operational Interdependence and Supervisory Experience on Management Assessments of Resource Planning Systems

Greater interdependence among workers and activities not only increases the need for internal communication, but it also imposes complications and barriers to effective information exchange. Intraorganizational communication capabilities of certain information systems can help overcome these barriers. However, the extent to which certain systems are promoted as communication tools depends largely on management's interpretation of their usefulness, which in turn may be largely dependent on operational context and managerial experience. We use a controlled experimental approach to study how these issues interact to impact managerial assessments of resource planning systems. Results show that managers value the communication capabilities of resource planning systems more so in highly task‐interdependent contexts and that these assessments are still more positive among managers with greater supervisory experience. As a result, these findings pose direct implications regarding the management support of technology use.     

Modeling Network Latency and Parallel Processing in Distributed Database Design

The design of responsive distributed database systems is a key concern for information systems managers. In high bandwidth networks latency and local processing are the most significant factors in query and update response time. Parallel processing can be used to minimize their effects, particularly if it is considered at design time. It is the judicious replication and placement of data within a network that enable parallelism to be effectively used. However, latency and parallel processing have largely been ignored in previous distributed database design approaches. We present a comprehensive approach to distributed database design that develops efficient combinations of data allocation and query processing strategies that take full advantage of parallelism. We use a genetic algorithm to enable the simultaneous optimization of data allocation and query processing strategies. We demonstrate that ignoring the effects of latency and parallelism at design time can result in the selection of unresponsive distributed database designs.     

HOW MANAGEMENT USERS VIEW INFORMATION SYSTEMS

The literature of management information systems suggests that substantial discord exists between management users and systems personnel. This paper describes the current attitudes of managers toward information systems and computers as reflected in seventy-five carefully structured interviews with managers from ten major companies. The author concludes that management user attitudes are quite favorable and do not reflect the predicted discord. In fact, the author believes that one of the major systems implementation problems of the future may be apathy rather than antipathy. The data collection was structured to indicate differences in attitudes on the part of users based on organizational level, functional area of work, type of activity, and type of environment.

The impact of autonomy on information systems planning effectiveness

Autonomy for information systems planning may have an impact on the effectiveness of that planning. Theory Y suggests that when managers have more autonomy, they have greater feelings of ownership, commitment, and responsibility, and thus perform better. A postal survey of 131 chief information officers of US subsidiaries of multinational firms collected data to test hypotheses based on the theory. Data analysis revealed that autonomy for IS planning in general and the strategy selection planning activity in particular significantly predicted IS planning effectiveness. These findings thus extend the theory to a new domain, namely IS planning in multinational firms, and thereby facilitate a better understanding of the management of IS planning. They further suggest that parent managers consider delegating greater autonomy to the managers of their foreign subsidiaries.     

A professionalization framework to understand the structuring of work

The notion of professionalization is widely used both by managers and researchers. This use questions the traditional definition of profession. This paper reviews a book published in 1988 – The System of Professions – written by a sociologist, A. Abbott. Though this book had a strong impact in the field of the sociology of professions, it has remained unknown by many researchers in management science. His pragmatic approach to the concepts of profession and professionalization helps achieve better understanding of work structuring and as a consequence can be useful to address issues such as human resources management, organizational control or even the management of information systems.     

Organizing for Global Competition

Global information technology (i.e., computer hardware, software, and data communications shared across country boundaries) can support the multinational firm as it seeks to coordinate global operations, diffuse innovations worldwide, or provide integrated service to a global corporate customer. The current study uses information processing theory as the basis for examining alternative organizational designs for information technology in a globally competing firm. Mail survey data gathered from information technology managers in 109 multinationals provide evidence that multinational firms use different and distinct ways of organizing their global information technology activities. The survey data also reveal that in nearly half of the organizations, the way information technology activities are organized is inconsistent with the way the organization is reportedly structured. A follow-up interview-based study sought explanations for these misfits. Several contingency variables were identified that may shed some light to the misfits. These included factors from both the firm's internal and external environments.     

Managing Enterprise Risks of Technological Systems: An Exploratory Empirical Analysis of Vulnerability Characteristics as Drivers of Exploit Publication*

Enterprises experience opportunistic exploits targeted at vulnerable technology. Vulnerabilities in software‐based applications, service systems, enterprise platforms, and supply chains are discovered and disclosed on an alarmingly regular basis. A necessary enterprise risk management task concerns identifying and patching vulnerabilities. Yet it is a costly affair to develop and deploy patches to alleviate risk and prevent damage from exploit attacks. Given the limited resources available, technology producers and users must identify priorities for such tasks. When not overlooked, vulnerability‐patching tasks often are prioritized based on vulnerability disclosure dates, thus vulnerabilities disclosed earlier usually have patches developed and deployed earlier. We suggest priorities also should focus on time‐dependent likelihoods of exploits getting published. We analyze data on software exploits to identify factors associated with the duration between a vulnerability discovery date and the date when an exploit is publicly available, a time window for patching before exploit attack levels may escalate. Actively prioritizing vulnerability patching based on likelihoods of exploit publication may help lessen losses due to exploit attacks. Technology managers might apply the insights to better estimate relative risk levels, and better prioritize protection efforts toward vulnerabilities having higher risk of earlier exploitation.     

风险环境下企业信息系统项目控制对绩效的影响机制研究:基于项目经理和用户代表的双重视角

虽然当前项目管理水平不断提高,但是企业信息系统项目实施的成功率仍然不容乐观。项目干系人缺乏准确的相互认知和角色定位,以及风险与控制的关系无法有效处理是导致项目绩效偏低的重要原因。为了从不同视角探索风险和控制对企业信息系统项目绩效的共同作用,通过对65位项目经理和63位用户代表所经历的128个项目的调查,利用结构方程模型进行实证分析,并采用层次回归分析技术进行检验。实证结果表明,正式控制和非正式控制对信息系统项目绩效都具有积极的影响,但是项目经理认为正式控制具有更加重要的作用,而用户代表认为非正式控制的作用更为显著。此外,项目经理和用户代表均认为组织风险和技术风险会减弱正式和非正式控制对绩效的有效作用。因此在控制方式的选择和组合上不仅要基于项目自身的特点,而且要基于干系人的角色。同时,信息系统项目绩效并非单纯由成功或失败因素所决定,而是取决于两类因素的均衡程度。研究结论为信息系统项目的风险控制提供了全新的理论依据和决策支持。     

A Methodology for Constructing Collective Causal Maps*

This article develops a new approach for constructing causal maps called the Collective Causal Mapping Methodology (CCMM). This methodology collects information asynchronously from a group of dispersed and diverse subject‐matter experts via Web technologies. Through three rounds of data collection, analysis, mapping, and interpretation, CCMM constructs a parsimonious collective causal map. The article illustrates the CCMM by constructing a causal map as a teaching tool for the field of operations management. Causal maps are an essential tool for managers who seek to improve complex systems in the areas of quality, strategy, and information systems. These causal maps are known by many names, including Ishikawa (fishbone) diagrams, cause‐and‐effect diagrams, impact wheels, issue trees, strategy maps, and risk‐assessment mapping tools. Causal maps can be used by managers to focus attention on the root causes of a problem, find critical control points, guide risk management and risk mitigation efforts, formulate and communicate strategy, and teach the fundamental causal relationships in a complex system. Only two basic methods for creating causal maps are available to managers today—brainstorming and interviews. However, these methods are limited, particularly when the subject‐matter experts cannot easily meet in the same place at the same time. Managers working with complex systems across large, geographically dispersed organizations can employ the CCMM presented here to efficiently and effectively construct causal maps to facilitate improving their systems.     

Using a stress audit: The construction site manager experience in the UK

The aim of this study was to conduct a stress audit among construction industry site managers in the UK as a precursor to a stress management intervention programme. Qualitative data were obtained from in-dept interviews with a total of 36 male middle and senior construction site managers; and aquantitative data were obtained by questionnaire. Based on the analysis of 561 postal quenstionnaires, eight stressor factors were identified, most significantly, ambiguity (i.e. role and task). Job satisfaction levels were low compared to a normative population and influenced by grade level. Measures of mental health were similar to the norm for males, but both grade of management and type of contract affected mental health. Anxiety levels were signficantly high, independent of managerial grade. The stress of work overload and role insecurity (fear of failure) were associated with reduced mental health and high anxiety, and the stress of the organizational culture and climate was the strongest predictor of job dissatisfaction. There was some cause for concern for the vulnerable high-risk groups, i.e. the extreme type A and those working overtime. Medical data from a small subset of managers (n = 78) revealed that this group evidenced a better quality of psychological health than the group in total; but a high percentage of personnel had high levels of triglycerides and cholesterol. Recommendations for action focused on the needs of specific subgroups, and guided the organization on the acceptability of possible interventions at individual, interpersonal and organizational levels.     

The bureaucratic side of computers: Memory,evocation and management information

Management information systems fail to support management because they are not flexible enough to keep pace with the unstructured nature of decision making processes. Observations made in four welfare management information systems suggest that computerization improves evocation—the means by which decision makers pool data from the collective memory, only to the extent that choices and the relevancy of data are predetermined. Facing rigid procedures and irresponsiveness to irregular data needs, managers of all ranks duplicate the computerized memory with manual records and files so as to retain access to their memory under their terms.     

Technology management: Fundamental issues for engineering education?

Although technology management has been a subject of concern in recent years, its importance to the technical community is not well established. The fundamental implications of technology management for the engineering profession is explored. A definition of technology is sought that best communicates the full implications of the term. In particular, the importance of knowing “how to apply” in contrast to understanding the “scientific fundamentals” is developed as a basis for defining technology.It is concluded that the current attention being given to technology management has significant fundamental implications for engineering and business education. Technology management is shown to focus attention on the importance of decision making processes for engineers and managers. It is concluded that including decision making as a fundamental engineering process may provide a new basis for structuring the “non-science” part of engineering curricula and provide a link between engineering and business curricula. Coupling this with a recognition of the differing characteristics of what is defined as Science Knowledge and Application Knowledge may provide a new paradigm for better preparing engineering students for entering professional practice and also provide a new basis for planning professional development and life long learning.     

Development of an integrated information management model: A case of textile industry

For past two decades many organisations have tried to implement integrated information management systems for better production management based on co-ordination of information and therefore activities of different departments. Although Enterprise Resource Planning systems have been in the market for the past decade, many industries find it difficult to implement such systems due to the amount of work involved in streamlining the documentation, customisation and of high costs reported in implementation. An attempt is made through this paper to propose an integrated model, which can be easily understood by production personnel, with specific emphasis on the textile sector.

Capacity Planning and Allocation for Web‐Based Applications

Motivated by the technology division of a financial services firm, we study the problem of capacity planning and allocation for Web‐based applications. The steady growth in Web traffic has affected the quality of service (QoS) as measured by response time (RT), for numerous e‐businesses. In addition, the lack of understanding of system interactions and availability of proper planning tools has impeded effective capacity management. Managers typically make decisions to add server capacity on an ad hoc basis when systems reach critical response levels. Very often this turns out to be too late and results in extremely long response times and the system crashes. We present an analytical model to understand system interactions with the goal of making better server capacity decisions based on the results. The model studies the relationships and important interactions between the various components of a Web‐based application using a continuous time Markov chain embedded in a queuing network as the basic framework. We use several structured aggregation schemes to appropriately represent a complex system, and demonstrate how the model can be used to quickly predict system performance, which facilitates effective capacity allocation decision making. Using simulation as a benchmark, we show that our model produces results within 5% accuracy at a fraction of the time of simulation, even at high traffic intensities. This knowledge helps managers quickly analyze the performance of the system and better plan server capacity to maintain desirable levels of QoS. We also demonstrate how to utilize a combination of dedicated and shared resources to achieve QoS using fewer servers.
