Differential effects of ERP systems on user outcomes—a longitudinal investigation

Adopting a model of job enrichment we report on a longitudinal case investigating the perceived impact of an Enterprise Resource Planning (ERP) system on user job design characteristics. Our results indicated that in the context of an ERP geared towards centralisation and standardisation the extent to which users perceived an increase or decrease in job enrichment was associated with aspects such as formal authority and the nature of their work role. Experienced operational employees proficient in the original legacy system perceived ERP system protocols to constrain their actions, limit training and increase dependence on others in the workflow. Conversely, managerial users reported a number of benefits relating to report availability, improved organisational transparency and increased overall job enrichment. These results supported our argument concerning the relationship between ERPs with a standardisation intent and positive job enrichment outcomes for managerial users and negative job‐related outcomes for operational users.

The role of ICTs in the servitisation and degradation of IT professional work

Recently IT work has been subjected to management approaches that apply production methods to service work. Specialised information and communication technologies (ICTs) used by IT professionals have played an important role in this ‘service turn’, but this has not been adequately explored in the literature. Via a qualitative study of IT professionals situated across the servitised IT functions of five UK‐based organisations, this article considers how these ICTs are inscribed with managerial logics that afford control benefits to managers while undermining professional autonomy and job quality. The article makes two main contributions to the literature. Firstly, it sheds light on how ICTs introduced into organisational IT functions support managerial control objectives and impact the job quality of IT professionals. Secondly, it suggests that ICTs may infect the logic of professionalism that takes pride in the quality of the work performance with a dominant managerial logic that places an emphasis on meeting management objectives.     

The dynamics of factors affecting the adoption of innovations

An abundance of IT innovations are constantly struggling for market acceptance. Various models have been proposed in the literature in order to aid understanding of the principles behind the adoption of IT innovations, but most of them implicitly assume that the factors explaining adoption decisions do not change over time. This study challenges that assumption and adds to the existing literature by investigating the dynamics of the factors influencing adoption. Our general proposition is that the driving factors in adopting innovations will change as the diffusion of the innovation in the market progresses. A large-scale empirical study was carried out among medium-sized companies in a variety of European countries and industries concerning the adoption of enterprise resource planning (ERP) software. The findings strongly indicate that the factors affecting late adoption of ERP differ significantly from the factors explaining early adoption. At early stages of the diffusion process adoption tends to be especially driven by a combination of internal strategic drives and attitudes of the firm together with external forces like industry competition and supplier activities. Later on, the mix of adoption stimulating factors seems to be focusing more on implementation issues such as the scalability of the system, the number of seats and the yearly available budget. The study leads to both new methodological insights and substantive conclusions that also have practical implications.     

Technology empowerment: A path to poverty alleviation for Chinese women from the perspective of development communication

By 2020, China had won a comprehensive victory in poverty alleviation, having completed the largest poverty alleviation task in human history and provided a Chinese solution to poverty alleviation worldwide. From the perspective of development communication and through the case study approach, this paper focuses on the practice of poverty alleviation conducted by Chinese rural left-behind women with the help of Internet technology. Furthermore, the paper summarizes three main forms of women's poverty alleviation, including the model of Internet celebrities using social media to sell local products; the model of the government taking the lead in building an online learning, training and sales platform; and the model combining government guidance, enterprise empowerment and media promotion. This paper explores the paths to poverty alleviation and the sustainable development of poor Chinese women in rural areas. It also provides a reference for the future practice of women's poverty alleviation for developing countries and regions.     

Information technology change,work complexity and service jobs: a contingent perspective

We examine the contingent impact of implementing an enterprise‐wide information technology system (Enterprise Resource Planning) on perceptions of work complexity in clerical, technical and managerial service sector jobs. Using matched and control samples of employee survey data, we compare pre‐ and post‐intervention perceptions of work complexity and importance of analytical skills across three hierarchical job levels: clerical, technical and managerial. We find that employees in clerical jobs, at the lowest level in the hierarchy, experience a significant increase in work complexity and need for analytical skills, whereas those in technical and managerial service jobs do not. Implications for theory, management of technology and employment policy are discussed.     

Pursuing consumer empowerment in the age of big data: A comprehensive regulatory framework for data brokers

Data brokers play a central role in the big data ecosystem, compiling personal data from numerous sources and subsequently selling them to businesses worldwide. Such practices, however, generally occur clandestinely without consumers' knowledge or consent and can harm consumers in a discriminatory manner. In recent years, US policymakers have been urged to regulate data brokers by promoting individual choice but have failed, whereas the European Union has introduced broad data privacy guarantees for consumers and a data protection regime that limits data brokers' activities if consumers' consent has not been obtained for specific purposes. Because of the power imbalance between consumers and data brokers, the author argues that the European Union's coherent data protection framework serves as an effective model for regulating data brokers.     

Strategic planning in a turbulent environment: evidence from the oil majors

The long‐running debate between the ‘rational design’ and ‘emergent process’ schools of strategy formation has involved caricatures of firms' strategic planning processes, but little empirical evidence of whether and how companies plan. Despite the presumption that environmental turbulence renders conventional strategic planning all but impossible, the evidence from the corporate sector suggests that reports of the demise of strategic planning are greatly exaggerated. The goal of this paper is to fill this empirical gap by describing the characteristics of the strategic planning systems of multinational, multibusiness companies faced with volatile, unpredictable business environments. In‐depth case studies of the planning systems of eight of the world's largest oil companies identified fundamental changes in the nature and role of strategic planning since the end of the 1970s. The findings point to a possible reconciliation of ‘design’ and ‘process’ approaches to strategy formulation. The study pointed to a process of planned emergence in which strategic planning systems provided a mechanism for coordinating decentralized strategy formulation within a structure of demanding performance targets and clear corporate guidelines. The study shows that these planning systems fostered adaptation and responsiveness, but showed limited innovation and analytical sophistication. Copyright © 2003 John Wiley & Sons, Ltd.

Contingent value of director identification: The role of government directors in monitoring and resource provision in an emerging economy

Research summary: Although previous studies have explored the value of government directors, less attention has been directed at the antecedents of government directors' engagement in value‐adding activities, such as managerial monitoring and resource provision. Drawing on social identity theory, we offer a novel model that specifies how a government director's dual identifications with the focal firm, and with the government individually and interactively affect his or her governance behavior. An investigation of government directors in China shows that their identification with the focal firm enhances monitoring and resource provision, while their identification with the government affects monitoring and resource provision differently. depending on the dominance of state ownership. The synergistic/substitutable effects between the two types of identification are contingent on state ownership and governance roles. Managerial summary: This study examines how a government director's dual identities—as a government official and as a board member of a focal firm affect his or her engagement in managerial monitoring and resource provision. Using data of Chinese listed firms, we find that government directors who strongly identify with the focal firm or with the government are highly motivated to fulfill their fiduciary obligations. However, the positive effects of their identification with the government differ between state‐owned enterprises (SOEs) and non‐SOEs. The combination of the two identifications offers a further boost to monitoring in non‐SOEs, and to resource provision in both SOEs and non‐SOEs, but it acts as a disincentive to monitoring in SOEs.

Derivation of confidence intervals of service measures in a base-stock inventory control system with low-frequent demand

We explore a base-stock system with backlogging where the demand process is a compound renewal process and the compound element is a delayed geometric distribution. For this setting it holds that the long-run average service measures order fill rate (OFR) and volume fill rate (VFR) are equal in values. However, though equal ex ante one will ex post observe differences as actual sample paths are different. By including a low-frequency assumption in the model, we are able to derive mathematical expressions of the confidence intervals one will get if OFR and VFR are estimated in a simulation using the regenerative method. Through numerical examples we show that of the two service measures it is OFR that in general can be estimated most accurately. However, simulation results show that the opposite conclusion holds if we instead consider finite-horizon service measures, namely per-cycle variants of OFR and VFR.     

Predicting the cost of environmental management system adoption: the role of capabilities,resources and ownership structure

This research explores why some facilities accrue greater costs when adopting an environmental management system (EMS) and why costs vary among three different ownership structures. Using survey data of organizations that documented their EMS adoption costs over a 3‐year period, the results show that publicly traded facilities had stronger complementary capabilities prior to EMS adoption and therefore lower adoption costs. By contrast, government facilities and privately owned enterprises had fewer capabilities and accrued higher EMS adoption costs. The development of organizational capabilities and resources therefore appears to be a function of both organizational exploitation of imperfect or incomplete market factors, and the institutional context of these decisions.
