| Summary: | 碩士 === 中原大學 === 企業管理學系 === 85 === The topic of information systems outsourcing (IS outsourcing) is an important subject under discussion, but there are few domestic to probe into the topic. In addition, there is few integrate research framework about IS ortsourcing, so the srudy attemps to establish and explain the framework of expounding the relationships between subjects, whicg related with IS outsourcing, with IS outsourcing and to propose the methods of conducting IS outsourcing successfully.
The study raises six hypothesizes after studying related papers including:
1.IS outsourcing decisions are positively related to the perceived discrepancy in the performance of IS outsourcing , and the high deprivation group will be more likely to outsourcing than the equilibrium group which in turn, will be mor likely to outsource than the saturated group.
2.IS outsourcing decisions are related to a firm''s particular strategy type:defender, prospector, analyzer, or reactor.
3.ISoutsourcing decisions will differ across the four different strategic roles of IT in the firm:support role, factory role, turnaround role, or strategic role.
4.The degree of outsourcing will be positively related to outsourcing success.
5.The association between the degree of outsourcing and outsourcing success is moderated by the level of service quality.
6.The association between the degree of outsourcing and outsourcing success is mediated by the quality of partnership between the service the provider and the firm.
Five performance measures for IS resources are examined in the current study: information quliity, IS staff quality, IS cost effectiveness, and firm''s financial performance. Five component functions of IS outsourcing are examined for their relationships with outsourcing success: applications development, systems operations, telecommunications, end-user support, and systems planning and management.
The study mailed questionnaires to the sample companies. There are 400 IS department managers being invited to fill the questionnaire and 104 questionnaires are available.
The main findings of the study are listed below:
1.IS outsocrcing decisions are positively related to the perceived discrepancy in the performance of information quality, IS support quality, and IS cost effectiveness. IS outsocrcing decisions are not positively related to the perceived discrepancy in the performance of IS staff quality, and firm''s financial performance.
2.The relationship between Miles and Snow''s strategy types and outsourcing decisions are not positively related.
3.The relationship between the IT strategy roles of MoFarlan et al and outsourcing decisions are positively related.
4.The degree of system operations and telecommunications outsourcing will be positively related to outsourcing success. The degree of applications development, end-user support, and systems planning and management outsourcing will not be positively related to outsourcing success.
5.Applications development and systems planning and management show a significant moderating effect of service quality.
6.Applications development and systems operations show a significant mediating effect of partmership.
The counsel of the study are listed below:
1.The considerations that decisions to outsourcing information systems functions are not only cost discrepancy, but also quality discrepancy.
2.The outsourcing degrees of system operations and telecommunications are higher, also there are more knowledges and experiences for outsourcing venders in the two items.
3.Overall service quality show a significant moderating effect, and parnership show a significant mediating effect, so the service quality and partnership should be importance.
