Although there are many processes in which factors interact with each other during enterprise resource planning(ERP) implementation, factors affecting ERP implementation have been investigated in an isolated way. In order to bridge the gap, this study attempts to provide a research model to explain how these factors affect ERP implementation success from a holistic perspective. In particular, this research focuses on how bundling and leveraging processes affect ERP implementation success using resource based theory, a strategy formulation framework, and a dynamic resource management model of value creation. The model amalgamates organizational resources and capabilities via the bundling and leveraging processes to identify the effect on ERP implementation success. This paper validates the proposed model by presenting Australian aviation industry case study. Case findings will be in help to reveal the effect of resource bundling in establishing capabilities and effect of capabilities leveraging in deriving the ERP implementation success.

As customers are becoming increasingly important in corporate management, there is a growing demand for migration to customer-focused organizational structures. Unlike the manufacturing industry, the construction industry is non-iterative and non-standardized. As a result, a wide variety of materials, human resources, technologies and equipment must be mobilized in complex work activities to complete a structure. Consequently, surprises are bound to occur as such work activities progress. This paper intends to study a strategy that is designed to improve customer services for apartment building units. It aims primarily to focus on cost control and brand management. Housing tenants and industry experts are surveyed to collect input for issue analysis. In addition, the external circumstances and internal capabilities of major builders in Korea are analyzed, and a SWOT analysis is performed regarding market conditions related to customer service. These analysis results are utilized to develop a strategy implementation plan over different time frames, and the operational resources available for such strategy implementation are analyzed in order to forecast its performance. This research will facilitate communication between construction companies in Korea and their customers by proposing a customer service improvement strategy for apartment building units, and is expected to provide resource material for a strategic analysis of efforts to fully incorporate customer requirements

The study reports a preliminary analysis for the No-Gun Ri massacre documentation strategy based on Hackman and Wornow-Blewett's implementation model, as an appraisal and selection method for No-Gun Ri Digital Archives. It intends to review the theoretical background for this process, inlcuding a history of the No-Gun Ri massacre and the development of documentation strategy. From the theoretical analysis, this study identified the No Gun Ri documentation strategy processes in 5 categories: "cooperative collecting", "collecting in specific areas", "identifing missing areas" and "advisory group". With these 5 categories, this study discusses the application of the Hackman and Wornow-Blewett's implementation model in the No Gun Ri case and reviews the strategy's pros and cons. As a result, firstly, we classfy focusing groups into "victims and bereaved family", "government", "civil society", "the press" and "literature and art". Secondly, we also classify documentation categories into "massacre records", "investigation activity records" and "cherish memory".

Recently, implementing ERP(Enterprise Resource Planning) systems has been one of major concerns of many companies. Despite the trend in the business area, few theoretical researches about the ERP have been published to date. The primary propose of current study, therefore, lies in examining the effects of change management characteristics on ERP performance. Top management support, user participation, and consulting support were selected as change management characteristics. Additionally, ERP implementation characteristics were considered as contingency variables which may moderate the relationships between change management characteristics and ERP performance. Two ERP implementation characteristic variables introeuced in this study were ERP implementation approach and ERP implementation strategy. Hypotheses concerning the relationships among those variables of change management characteristics. ERP performance and ERP implementation characteristics were empirically tested. The findings show that change management characteristics are strongly correlated with ERP performance, and ERP implementation characteristics have contingency effects, partially at least, on the relationship between change management characteristics and ERP performance.

Commonality strategy is a popular design practice in designing a product line as it enables the firm cost saving and simplification in design, manufacturing, and distribution processes. However the issue of commonality has been mostly analyzed from a profit maximizing firm's perspective and, to our knowledge, there is no literature that deals with the issue from a different perspective. in this paper, we consider the issue of commonality strategy from a social welfare maximization perspective, and argue that commonality strategy used in designing of public goods can bring certain benefits not just for a firm but also for consumers, i.e., for society as a whole. While we assume certain cost saving in production process due to economies of scale under commonality strategy, we conceptualize two different effects of commonality strategy, utility effect due to cost saving and weighted-averaging effect, and show how these two effects interplay to determine the design of common attribute and desirability of commonality strategy. We also discuss how the implementation of commonality strategy differs under different objectives of a product line designer : social welfare and firm's profit maximization.

Use of ICT in Government has ability to improve service delivery to its citizens, and yet many developing countries have lagged behind in the implementation of e-Government. Many e-Government initiatives also failed to achieve their objectives in developing countries. This paper therefore aims to identify critical failure or success factors in Kenya, using Heeks' Factor Model. A survey questionnaire was developed and data were collected and analyzed from officials and interested citizens. The analysis results enabled to highlight seven specific success and failure factors, and their constituent elements in Kenya. The Kenyan overall e-Government implementation score belongs to the Zone of Improvement (3.52 of total 5.0), which means partial success or failure. The enablers of e-Government projects are good strategy formulation, and internal and external drive, whereas main failures of e-Government are weak ICT infrastructure. The areas for improvement are project management, design, competencies and funding. Data analysis highlights both strengths and weaknesses for each factor or variable. In particular, Kenyan government excels at the drive for change by top to bottom government officers as well as external stakeholders, while the government officers who are using e-Government are satisfied with the availability of vision, strategy and plan of e-Government implementation. Both technologies and e-transactions laws were the worst of all the variables in e-Government implementation. Two areas should be improved using immediate corrective action. In-depth study reveals that government officers and citizens can't fully use their laptop and mobile devices due to the lack of both ICT network and its operating technology, and legal system associated with the transaction of business information. Finally, the study ends up with recommendations for policy makers to shape the future of e-Government system in both developing and developed countries.

In this paper, a novel overmodulation strategy for space-vector PWM(SVPWM) inverters to utilize dc link voltage fully Is presented. The proposed strategy uses the concept of SVPWM based on the zero sequence signal(offset voltage) injection principle. So, by modifying the pole voltage simply, the linear control of inverter output voltage over the whole overmodulation range can be achieved easily The proposed strategy is so simple that its practical implementation is easy. The validity of the proposed strategy is confirmed by the experimental results.

In this paper, behaviors performing controls of a mobile robots are designed based on the concept of closed-loop controls. A control architecture, in which the behaviors coordinate concurrently with one others to achieve a task is also proposed. In the control architecture, task manager allocates valid resources and configures the weight of the behavior outputs to achieve the task. For practical implementation, a rate modulation strategy based on RMS(Rate Modulation Strategy) is proposed for efficient resource allocations. The rate modulation strategy is performed with considering control stability. The efficiency of the proposed rate modulation strategy is validated through simulation tests.

The basic assumption of analytical Dynamic Traffic Assignment models is that traffic demand and network conditions are known as a priori and unchanging during the whole planning horizon. This assumption may not be realistic in the practical traffic situation because traffic demand and network conditions nay vary from time to time. The rolling horizon implementation recognizes a fact : The Prediction of origin-destination(OD) matrices and network conditions is usually more accurate in a short period of time, while further into the whole horizon there exists a substantial uncertainty. In the rolling horizon implementation, therefore, rather than assuming time-dependent OD matrices and network conditions are known at the beginning of the horizon, it is assumed that the deterministic information of OD and traffic conditions for a short period are possessed, whereas information beyond this short period will not be available until the time rolls forward. This paper introduces rolling horizon implementation to enable a multi-class analytical DTA model to respond operationally to dynamic variations of both traffic demand and network conditions. In the paper, implementation procedure is discussed in detail, and practical solutions for some raised issues of 1) unfinished trips and 2) rerouting strategy of these trips, are proposed. Computational examples and results are presented and analyzed.
