- This study explores the factors that can impact individual performance when using enterprise resource planning (ERP) systems. Starting from the proposition that organizational performance depends on individuals' task accomplishments, we test a structural model of task-technology fit, ERP user satisfaction, and individual performance in ERP environments. This research utilizes a survey method to examine the perceptions of ERP users. We performed factor and reliability analyses to assess the validity of the survey instrument. Six factors were identified as having an impact on individual performance: System Quality, Documentation, Ease of use, Reliability, Authorization, and Utilization. To explore the relationships among these factors, we conducted regression and multivariate adaptive regression splines analysis, and compared the findings from these two analytical techniques. The study provides evidence that System Quality, Utilization, and Ease of Use are the most important factors bearing on individual performance in ERP environments. Our findings also provide IT managers and researchers with knowledge of how these factors can be manipulated to improve individual performance when using ERP systems.

- Information systems outsourcing is now almost standard practice for many companies. Outsourcing the information processing activities is a complex issue that entails considerable implications for the strategy of the firm. An important mechanism for managing the performance of outsourcing vendors is incentive contracts. But to develop an outsourcing contract the IS manager must quantify risks and benefits. However methods and tools for analyzing and quantifying outsourcing risks that IS managers have at their disposal are rudimentary. In this paper we offer a method and some mathematical models for analyzing risks and constructing incentive contracts for IS outsourcing. We are aware that most managers do not like to use mathematical models, consequently we have minimized the technical discussion and have illustrated how this model could be implemented using spreadsheet software for ease of use.

- Predicting successful implementation of enterprise resource planning (ERP) systems is still an elusive problem. The cost of ERP implementation failures is exceedingly high in terms of quantifiable financial resources and organizational disruption. The lack of good explanatory and predictive models makes it difficult for managers to develop and plan ERP implementation projects with any assurance of success. In this paper we investigate the Klein & Sorra theoretical model of implementation effectiveness. To test this model we develop and validate a data collection instrument to capture the appropriate data, and then use multivariate adaptive regression splines to examine the assertions of the model and suggest additional significant relationships among the factors of their model. Our research offers new dimensions for studying managerial interventions in IT implementation and insights into factors that can be managed to improve the effectiveness of ERP implementation projects.
