| Summary: | 碩士 === 國立臺灣大學 === 資訊管理學研究所 === 92 === In recent years, due to the rapid development of information technology, organizational investments in IT are increasing substantially. However, many empirical studies in the past do not definitely indicate the corresponding improvements on the relationship between IT investments and organizational perfor- mance.Bryjolfsson(1993) pointed out the shortcomings in the past researches, including mismeasurements of input and output datas, lags between cost and benefits, redistribution and dis- sipation of profits, mismanagement of IT. Moreover,from resea- rches of Sircar et al.(1998),Shafer & Bryd(2000),Santhanam & Hartono(2003), they also have obtained the great results,show-
ing this issue is worth for doing the research.Again,the resu-lts show the importants of the evalution in organizational IT investments.
To solve these problems, clearly, we need the proper IT ev- aluation methodologies that can eliminate disadvantages propo- sed by Bryjonlfsson(1993), and a way to improve the resource management in IT investments.This paper proposes a framework for evaluating investments in IT.In this study, we illustrate with more than 200 Taiwanese companies which belong to differ- ent industries, including IT investments and several business outputs. The datas used to validate the framework exceed that used in previous analyses in both quality and quantity.There- by,the study can provide an appropriate analysis. Through res- earch process,framework application and ananlysis, these resu- lts we have found facilitate us to believe if an organization can manage IT resources well, IT investments will have positi- ve effects on organizational performance.
