We investigated perceptual similarity and the difference between client and vendor in information technology (IT) outsourcing projects. Specifically, we focused on each player's perception of how the fit of governance and peripheral knowledge affects the performance of IT project outsourcing. For 107 IT projects, we surveyed both client and vendor in the same IT projects and compared the responses of each side. Through a dyadic analysis, we first found that both client and vendor put more weight on the vendor's peripheral knowledge than that of the client as a positive influencer of project performance. However, regarding the governance style of an IT project, client and vendor showed completely different perspectives. The client believed that the vendor's peripheral knowledge positively contributes to the performance of IT project under the governance of outcome control. However, the vendor showed that its peripheral knowledge creates synergy effects under the governance of process control. Our interpretation of the perceptual similarity and difference between client and vendor delivers managerial implications for businesses that process IT projects.

Due to the deterioration of the business environment, many companies become more interested in IT adoption to strengthen their internal competence. The recent expansion of the ERP adoption in the small and medium-sized enterprises (SMEs) can be interpreted as an example for this. However there are still a number of questions over the outsourcing effectiveness and its performance of IT adoption by characteristics of SMEs. This study aims to investigate the relationship between the software process quality and the product quality, and additionally the moderating effect of IT adoption factors, from the case of SMEs' ERP adoption by the outsourcing. For this purpose, the empirical analysis through the structural equation model has been carried out, based on the software quality model defined in ISO/IEC 15504 and ISO/IEC 9126. The result of analysis shows that the acquisition process quality can affect the product quality characteristics, currently applied in the national software quality certification, and this supports the practical usefulness of the ISO standard of software engineering. But another result shows that there is little moderating effect by IT adoption factors, in contrast to the expectation, and this can be explained due to the inappropriate measurement and the data constraint such as short duration-time of IT adoption. These can be used as an informative reference for continuing studies of the quality model application and the effect of IT adoption factors in SMEs.

In this study, small and medium-sized manufacturing and distribution businesses were asked to demonstrate how the risks that could arise from implementing ITOs affect their performance. Small and medium-sized enterprises that want to reduce costs or secure competitiveness through outsourcing ITO conducted research to identify and analyze risks of ITO and improve corporate performance. Strategic, technical, and financial risks were selected as independent variables for analysis by the survey method. In addition, relationship risk was selected as a parameter and corporate performance was selected as a dependent variable to conduct a path analysis. The analysis showed that the variables injected as independent variables had indirect and total effects on corporate performance. This can be interpreted as the higher the level of awareness of strategic and technological risks and financial risks, the higher the level of relational risk, and thus the positive impact on corporate performance. We expect to improve corporate performance through analysis of more and more risk factors in the future.

Recently, a market size for IT outsourcing has grown. As internet technology has been developed for accessing information resources, information systems have become internet-based, which is called an ASP(Application Service Provider); evaluating the performance for ASP becomes important. Therefore, this paper attempts to investigate the salient characteristics of ASP. An ASP success model is proposed based on information systems success models found in the literature. Our model is tested through a survey from 291 small companies. LISREL is used to demonstrate the suitability of our model, and the success factors for ASP are also investigated. Our result is likely to help provide useful guidelines for the successful ASP implementations.

ASP service that is emerging as a new form of application outsourcing has the advantage of lower cost and risk. Therefore, ASP service may be attractive for small firms and even some new companies. However, studies about ASP service are rare in academic and professional journals, and most of the articles about outsourcing were considering mainly large enterprises. The purpose of this article is to analyze the effects of the some context variables of Korean small businesses on ASP service usage pattern, and the effect of ASP service usage pattern on user satisfaction and firm performance. The analysis results show that firm size has a positive impact on IT need of small businesses, and IT need of small businesses have a positive impact on training period and past usage period. Also, firm size, IT need, training period has an positive impact on ASP service usage pattern. However, ASP service usage period has no relationship on ASP service usage pattern. Finally, ASP service usage pattern has a positive impact on firm performance and user satisfaction, and user satisfaction has an impact on firm performance.

Recently, research on database encryption for data protection and query result authentication methods has been performed more actively in the database outsourcing environment. Existing database encryption schemes are vulnerable to order matching and counting attack of intruders who have background knowledge of the original database domain. Existing query result integrity auditing methods suffer from the transmission overhead of verification object. To resolve these problems, we propose a group-order preserving encryption index and a query result authentication method based on the encryption index. Our group-order preserving encryption index groups the original data for data encryption and support query processing without data decryption. We generate group ids by using the Hilbert-curve so that we can protect the group information while processing a query. Finally, our periodic function based data grouping and query result authentication scheme can reduce the data size of the query result verification. Through performance evaluation, we show that our method achieves better performance than an existing bucket-based verification scheme, it is 1.6 times faster in terms of query processing time and produces verification data that is 20 times smaller.

Focal companies (hereafter called buyers) adopt outsourcing practices from a supply chain management strategy to be competitive. Buyers face the bridge transfer after outsourcing contracts, and the monitoring practices would be the only control mechanism left to prevent losing control over the suppliers. This study suggests the set of monitoring practices (i.e., capability, activity and outcome monitoring) as the independent variables to enhance the buyer-supplier collaboration and supplier's performance. In addition the buyer's efforts of monitoring are assumed to influence the buyer's shop floor productivity mediated by the supplier's performance and buyer-supplier collaboration. The results showed that the monitoring practices are meaningful antecedents to the supplier's performance and buyer-supplier collaboration, which fully mediates between the monitoring practices and buyer's shop floor productivity. The mediating role of the buyer-supplier collaboration between activity monitoring and shop floor productive has been rejected, because the negative effect of activity monitoring on buyer-supplier collaboration conflicts with the positive impact of buyer-supplier collaboration on shop floor productive. The theoretical contribution and managerial implications with limitations have been discussed.

Even though logistics service outsourcing becomes widespread in manufacturing and service industries, logistics service providers encounter fierce competition and lower profit. Decreased profit has negative impact on service providers' competitiveness, which in turn threats successful relationship with shippers. In this paper, we investigate the factors which influence the performance of service providers. Factors related to service contract are examined and we test an effect of concreteness and fairness of service contract. PLS (Partial Least Square) modeling method is applied and validated using data from logistics service providing companies in Korea. In the model, service contract clauses are classified into two categories including cost and risk sharing terms. PLS analysis shows that partnership and performance of service relationship is improved when contract clauses are specified in detail. This study will contribute in providing an operational direction in effectively establishing a positive relationship between the logistics service provider and the shipper.
