IT capability and organizational performance: the roles of business process agility and environmental factors

The business value of information technology (IT) has been one of the top concerns of both practitioners and scholars for decades. Numerous studies have documented the positive effects of IT capability on organizational performance but our knowledge of the processes through which such gains are achieved remains limited due to a lack of focus on the business environment. Such a linkage therefore remains the subject of debate in the information systems literature. In this study, we fill this gap by investigating the mediating role of business process agility and the moderating roles of environmental factors. On the basis of matched survey data obtained from 214 IT and business executives from manufacturing firms in China, our analyses show that even though firm-wide IT capability presents the characteristics of rarity, appropriability, non-reproducibility, and non-substitutability, its impact on organizational performance is fully mediated by business process agility. Our results also show that the impact of the environment is multifaceted and nuanced. In particular, environmental hostility weakens the effect of IT capability on business process agility, while environmental complexity strengthens it. The theoretical and practical implications of this study, and its limitations, are also discussed.

From transactional user to VIP: how organizational and cognitive factors affect ERP assimilation at individual level

This study extends the enterprise resource planning (ERP) assimilation research from organizational level to individual level with the argument that it is the individual users who transform ERP systems’ capabilities into organizational performance. We employed a multi-case study method in this exploratory research with the objectives of defining individual level ERP assimilation and identifying key influential factors. Interviews with ERP users at all levels in five organizations revealed four key drivers: influence of supervisors, performance evaluation schemes, intrinsic motivation, and perceived usefulness, as well as two significant moderators: job specifications and individual absorptive capacity. Moreover, evidence suggests a potential relationship between individual level and organizational level ERP assimilations. Our findings highlight the importance of individual level assimilation within a firm in the post-implementation phase and provide managerial insights on how firms could improve ERP assimilation at the individual level that could impact the organizational level assimilation.     

The mediating effect of organizational culture and knowledge sharing on transformational leadership and Enterprise Resource Planning systems success: An empirical study in China

Senior leadership has been identified as a critical factor in fostering Enterprise Resource Planning (ERP) systems success, however, the specific impact mechanism of transformational leadership on ERP success is still largely unknown. Based on organizational culture theory and knowledge based view, this study developed a theoretical model to explore the mediating effect of organizational culture and knowledge sharing on transformational leadership and ERP success. Data was collected from 115 IS executives and 413 ERP end users in 115 organizations in China. Partial Least Squares (PLS) analysis results suggest that transformational leadership is directly related with all the four types of organizational culture – development culture, group culture, hierarchical culture and rational culture, and is indirectly related with knowledge sharing and ERP success. Specifically, development culture has direct impact on ERP success, while hierarchical culture, group and rational culture are indirectly related with ERP success, mediated by explicit and tacit knowledge sharing. The research findings can provide guidelines for the top executives to facilitate appropriate organizational culture, so as to foster ERP knowledge sharing and achieve business benefits with the assimilation of ERP systems.

Food safety management system performance in the lamb chain

This study describes a performance measurement of implemented food safety management system (FSMS) along the lamb chain using an FSMS-diagnostic instrument (FSMS-DI) and a Microbiological Assessment Scheme (MAS). Three slaughterhouses, 1 processing plant and 5 butcher shops were evaluated. All the actors along the lamb chain achieved a moderate risky contextual situation, operating in a basic-average FSMS, which was not enough to obtain a good food safety output. Different suggestions are advised for each actor along the lamb chain for improvements towards higher FSMS activity levels or lower risk levels in context characteristics. The combined assessment is a useful tool to identify the possible causes of poor food safety performance in the lamb chain using few sampling locations, saving time and money.     

新形势下做好广播电视内容监管工作的几点思考

随着广播电视事业的快速发展,监管模式也在不断发展.既要确保安全播出,又要做好播出内容监管,才能保证广播电视播出质量,更好地发挥监督监管作用.新形势下,广播电视播出具有多极化、多元化和多样化的特点,广播电视监管相应的就具有监管范围扩大、要求提高、难度增加的新变化.随着广播电视播出内容的日益丰富,做好节目内容监管,净化荧屏风气,具有重大现实意义.本文从分析目前广播电视播出现状入手,结合实际,对现阶段内容监管工作中面临的困难进行分析,提出一些做好内容监管工作的建议性观点.     

埕岛油田中低含水期提注开发试验

埕岛油田是河流相疏松砂岩油藏,初期采用温和注水政策,压力降低、液量下降等开发矛盾逐步暴露。为实现海上油田的高速高效开发,通过油藏数值模拟计算和分析,提高注采比可有效提高水驱效果,提高采油速度,实现高速高效开发。2005年7月井区开始提注,提注后对应受效油井出现明显增油效果,液量不断上升,开发形势明显好转。
