A Path to Successful IT Outsourcing: Interaction Between Service‐Level Agreements and Commitment
研究了服务水平协议（SLA）的三个特征集与外包成功的关系，以及承诺如何调节这种关系，发现不同外包目标需匹配不同合同维度，且承诺有时会阻碍SLA的有效使用。
ABSTRACT Although service‐level agreements (SLAs) are important for IT outsourcing management, appropriate mechanisms for constructing effective SLAs are still poorly understood, leading to inadequate or overcomplicated contracts that are ineffective. This study examines the associations among three distinct sets of SLA characteristics and outsourcing success, as well as the role of commitment in these relationships. Analyzing survey data based on a model theorizing the alignment of SLA characteristics with intended outsourcing objectives, we find that different types of benefits attained through IT outsourcing arrangements are associated with the use of specific contractual dimensions. We also find that commitment, in general, moderates the impact of SLAs on outsourcing success, although the nature of the moderation varies with the different benefits IT outsourcing engagement is intended to achieve. Interestingly, in certain cases—change characteristics for achieving technology benefits, in particular—commitment can be a barrier to the effective use of SLAs in achieving intended outsourcing benefits. As such, our study extends the literature on IT outsourcing, contracting and commitment, as well as provides a general guideline for practitioners to structure effective SLAs and to properly use commitment for managing IT outsourcing engagements to successfully achieve intended benefits.
