Enhancement of business agility is not possible unless greater flexibility is built into IT infrastructure. More often than not, MIS's today are not flexible enough in this sense to agilely accommodate demands for system change incessantly confronting them. We have been focusing our research on MIS flexibility, its evaluation and the development of methodology for its enhancement. This paper aims to present a comparative evaluation via future oriented POC (penalty of change) analysis of system alternatives involving a case of new technology implementation. To start with, we will define the concept of MIS flexibility. We will then describe an actual case of technology implementation and define the problem it involved and go on to illustrate the evaluation procedure of MIS flexibility via future oriented POC analysis.展开更多
