The herd behavior of technology users, i.e., adopters observe the decisions (but not the reasoning) of prior adopters and imitate their system usage behaviors, is prominentin the information technology (IT) industry. However, such en mass adoptions areprone to be fragile. Adopters may reverse their decisions, after an initial adoption, andabandon system use when updated contradictory information is presented. This phenomenon of herd-like abandonment, at both individual and organizational levels, is significant and requires more investigation, since it is connected to the durability of particular products and technologies in the marketplace. In addition, IS behaviors of users at the later phases of IS life cycle, i.e., termination phase, are the primary source of benefit for organizations. This study develops and empirically validates a theoretical model of IS abandonment in a herding context. We test our model via a longitudinal research design, which surveys adopters at two different points in time. The study examines the determinants of adopters’ abandonment intentions, which occure specially after an initial en mass adoption (i.e., a herding setting). Results suggest that post-adoptive task-technology fit, perceptions of niche, and observation of a criticalmass of abandoners are all salient factors affecting IS abandonment intentions.

技术用户的羊群行为，即采用者观察先前采用者的决策（而不是推理）并模仿他们的系统使用行为，在信息技术（IT）行业中较为突出。然而，这种大规模采用往往是脆弱的。在最初采用之后，采用者可能会改变他们的决定，并在出现更新的矛盾信息时放弃系统使用。在个人和组织层面，这种像羊群一样的放弃现象很重要，需要更多的调查，因为它与市场上特定产品和技术的耐用性有关。此外，用户在IS生命周期后期即终止阶段的IS行为是组织的主要利益来源。本研究开发并实证验证了在放牧背景下放弃 IS 的理论模型。我们通过纵向研究设计来测试我们的模型，该设计在两个不同的时间点对采用者进行调查。该研究考察了收养者遗弃意图的决定因素，这种情况特别发生在最初的大规模收养（即放牧环境）之后。结果表明，采用后任务技术的契合度、对生态位的看法以及对大量放弃者的观察都是影响 IS 放弃意图的显着因素。放牧环境）。结果表明，采用后任务技术的契合度、对生态位的看法以及对大量放弃者的观察都是影响 IS 放弃意图的显着因素。放牧环境）。结果表明，采用后任务技术的契合度、对生态位的看法以及对大量放弃者的观察都是影响 IS 放弃意图的显着因素。
