摘要：Dalmadge and Wong [1] identified an array of risk factors that contribute to the increase in system vulnerability, which may in turn trigger discontinuity in eBusinesses. Among others, scalability has been identified in the information systems literature as one of the most prominent risk factors for eBusinesses discontinuity. In this paper we use a popular network simulation tool to test the impacts of scalability on a network based student registration system. The objectives of the simulation are to: (i) evaluate the extent to which scalability affects system performance, and (ii) identify individual attributed of scalability that are most significant in determining the likelihood that an information system or eBusiness will perform at a desired level under increasing load. Our results supported the fact that scalability serves as a risk factor for eBusiness discontinuity but our number of simulation runs failed to deliver conclusive results on the individual attributes of scalability that serve as discriminator for eBusiness discontinuity.
