As information technology (IT) success is both essential and elusive, researchers and practitioners are faced with an ongoing challenge to determine what IT capabilities should be developed to ensure IT success. Drawing on the paradox and ambidexterity theory, we highlight paradoxes in IT success and propose that firms manage these paradoxes by developing an IT ambidexterity capability. We hypothesize that IT ambidexterity capability enhances IT success, and that uncertain environments strengthen this relationship. Our hypotheses find support in a sample of 292 British high-tech firms. This research contributes to conceptualize paradoxes in IT success and advances the theory for a more comprehensive understanding of the impacts of IT ambidexterity capability.

由于信息技术（IT）的成功既必不可少，也难以捉摸，因此研究人员和从业人员面临着不断的挑战，以确定应开发哪些IT能力以确保IT成功。利用悖论和歧义性理论，我们强调了IT成功中的悖论，并建议公司通过开发IT歧义性能力来管理这些悖论。我们假设IT的灵活性能够增强IT的成功，而不确定的环境会增强这种关系。我们的假设在292家英国高科技公司的样本中得到了支持。这项研究有助于概念化IT成功中的悖论，并推动了该理论的发展，从而可以更全面地理解IT灵活性的影响。
