Platform-based customer agility is the ability to leverage the voice of the customer on a platform to achieve market intelligence and to explore competitive action opportunities. Prior studies have indicated the critical role of customer agility in enabling the survival and prosperity of contemporary organizations in a turbulent business environment, although how to develop this capability is not answered. The current research attempts to fill this theoretical gap. Drawing on the information management literature, we propose an integrative information management framework to investigate the process of developing customer agility. By conducting a case study of a leading e-commerce platform in China, we identify three types of platform-based customer agility (i.e. reactive customer agility, proactive customer agility, and coactive customer agility) in different phases of the growth of the platform. Furthermore, a process model is developed from the case study. It shows that platform-based customer agility is achieved by establishing information management structure, developing information management capability, and instilling information management culture. This study contributes to the knowledge on customer agility and information management. Detailed recommendations are also provided for potential practitioners.  相似文献

As a core organizational resource, business processes are vital for organizational teams. To deal with today’s volatile business environment, organizations need to be ambidextrous in terms of process capabilities. However, little is known about how process ambidexterity, process standardization, and process agility, are enabled by information technology (IT) and related to team-level activities. To fill this gap in the literature, we conducted a field study based on 160 teams of 1081 individuals from seven companies in South Korea. Our results show that IT enables both process standardization and agility, and that a team’s process ambidexterity has a positive effect on inter-team coordination and team innovation, which in turn have a direct impact on team performance. Our findings highlight the importance of process ambidexterity by investigating the enabling role of IT and its outcomes in a team. Our results offer theoretical and practical implications from the perspective of team process ambidexterity.  相似文献

信息技术(IT)的快速发展对于实现企业的可持续发展机遇与挑战并存。信息技术的运用一方面会导致能源消耗、社会分化,另一方面绿色技术创新也为可持续发展提供了现实可能。但现有文献对IT能力的可持续发展价值及其过程研究较为匮乏。本文根据资源基础观,构建企业可持续发展绩效的整合模型。以214家汽车制造企业为样本,运用结构方程模型实证分析了IT能力对经济、社会和环境多层面可持续发展绩效的全面影响及其内在机制。实证结论发现IT能力有助于提升企业整体绩效表现,促进可持续发展绩效;业务流程敏捷性是IT能力重塑企业的关键环节,对于IT能力与可持续发展绩效之间的关系具有显著的中介效应。最后,本文基于上述研究发现提出相应的管理启示和未来方向。  相似文献

To determine the effect of circadian rhythm on neuromuscular responses and kinematics related to physical tennis performance, after a standardised warm-up, 13 highly competitive male tennis players were tested twice for serve velocity/accuracy (SVA), countermovement vertical jump (CMJ), isometric handgrip strength (IS), agility T-test (AGIL) and a 10-m sprint (10-m RUN). In a randomised, counter-balance order, tennis players underwent the test battery twice, either in the morning (i.e., AM; 9:00 h) and in the afternoon (i.e., PM; 16:30 h). Paired t-tests were used to analyse differences due to time-of-day in performance variables. Comparison of morning versus afternoon testing revealed that SVA (168.5 ± 6.5 vs. 175.2 ± 6.1 km · h?1; P = 0.003; effect size [ES] = 1.07), CMJ (32.2 ± 0.9 vs. 33.7 ± 1.1 cm; P = 0.018; ES = 1.46), AGIL (10.14 ± 0.1 vs. 9.91 ± 0.2 s; P = 0.007; ES = 1.23) and 10-m RUN time (1.74 ± 0.1 vs. 1.69 ± 0.1 s; P = 0.021; ES = 0.67) were significantly blunted during the morning testing. However, IS was not affected by time-of-day (P = 0.891). Thus, tennis performance may be reduced when competing in the morning in comparison to early evening. Therefore, coaches and tennis players should focus on schedule the SVA, power, speed and agility training sessions in the afternoon.  相似文献

This paper responds in part to a special edition of this journal (39/2) on dual-mode provision. We were concerned that contact providers might drift into distance education provision through extending campus-based online learning without first thinking through the underpinning implications of its administrative systems, an issue that was not addressed in the special edition. Proceeding from a pragmatic and constructivist perspective, while adopting a transactional orientation drawing on systems theory and hermeneutics, this paper focuses on the challenge for administrative staff and systems of the changing nature of provision in terms of both the underpinning learning and business models. Based on experience and reflection, we conclude that the move into dual- and multimode provision is inevitable and that this requires agility on the part of both administrative staff and systems that is often overlooked in planning and review processes.  相似文献

运用文献资料法和逻辑分析法对近十年网球体能训练理论相关论文进行综述,结果发现,中国网球体能训练理论研究起步较晚,取得科研立项的较少;网球相关体能训练论文虽多,但整体科研质量有待提高;目前的体能训练研究多集中在身体形态、技能和素质方面,对网球体能指标体系、体能训练结构模型及体能水平的评价研究尚不多见。因此,体能训练要加大安排体能训练的比例,根据网球专项特征科学实施理论素质、速度素质和耐力素质训练;混合供能训练并根据赛制特点进行以赛促练。  相似文献

The purpose of this study was to examine the ability of two educational leadership university programmes to improve the cognitive agility of their graduates. The research looked to discover whether the aspiring principals exited the programmes with an increased ability to employ cognitive agility – the ability to use the multiple thinking skills of systems thinking, reflecting, and reframing – when engaged in their professional work and solving problems. Both Masters programmes were in School Leadership, offered through the same university department and following the same core curriculum leading to Level 1 educational leadership certification. The results indicate that of the two programmes studied, the Principal Rapid Orientation and Preparation in Educational Leadership (PROPEL) programme, designed to prepare leaders for turnaround schools, produced more cognitively agile graduates than the traditional Master’s programme. The mediating variables of participants’ years of experience and budget responsibility increased the level of cognitive agility of both programme’s graduates.  相似文献

Abstract

In spite of the increased acceptance of artificial turf in football, few studies have investigated if matches are altered by the type of surface used and no research has compared physiological responses to football activity on artificial and natural surfaces. In the present study, participants performed a football match simulation on high-quality artificial and natural surfaces. Neither mean heart rate (171 ± 9 beats · min?1 vs. 171 ± 9 beats · min?1; P > 0.05) nor blood lactate (4.8 ± 1.6 mM vs. 5.3 ± 1.8 mM; P > 0.05) differed between the artificial and natural surface, respectively. Measures of sprint, jumping and agility performance declined through the match simulation but surface type did not affect the decrease in performance. For example, the fatigue index of repeated sprints did not differ (P > 0.05) between the artificial, (6.9 ± 2.1%) and natural surface (7.4 ± 2.4%). The ability to turn after sprinting was affected by surface type but this difference was dependent on the type of turn. Although there were small differences in the ability to perform certain movements between artificial and natural surfaces, the results suggest that fatigue and physiological responses to football activity do not differ markedly between surface-type using the high-quality pitches of the present study.  相似文献
