그룹지원시스템(GSS)의 사용 및 성과에 대한 집단의 전유방식의 영향|RISS 상세보기

다국어 초록 (Multilingual Abstract)

This study uses the Hierarchical Linear Modeling method to investigate the effects of individual and group level factors on the use of GSS (Group Support System) and task performance from GSS use. GSS facilitates the group work, so that GSS adoption is not necessarily influenced only by individual perceptions on information systems as TAM insists. Adaptive Structuration Theory (AST) joins with TAM in our study to explain the adoption and success from GSS use. AST contends that the success of IS is not necessarily the technical fit between tasks and technology, instead the political outcome among user socializations. However, a new analysis method is necessary when we put the different level of constructs, which are nested to each other in hierarchical relationship, in the same model like in our study. For example, when data are collected from individuals of multiple groups in organizations, individual analysis is not appropriate because individuals in the same group must have high correlation, which violates the assumption of independent analysis units. Meanwhile, aggregation to the group level contains the risk of shrinking the number of data points below the critical mass. In HLM, the variances of dependent variables are divided into individual and group levels, and groups level variances are further broken down to the slope and intercept effects.Appropriation of GSS is categorized into two types: consensus on appropriation (COA) that means the social agreement among group members on GSS usage, and faithfulness of Appropriation of GSS is categorized into two types: consensus on appropriation (COA) that means the social agreement among group members on GSS usage, and faithfulness of appropriation (FOA) that denotes the consistency between IS designer’s plan and user group’s actual usage pattern. In our research model, individual level constructs are the perceived usefulness (PU) and ease-of-use (PEU), while the group level constructs are COA and FOA.We collected data from 303 individual IT staffs of 40 teams in a national bank. Our results demonstrate that traditional theories on TAM (Technology Acceptance Model) need to be refined, when considering the GSS appropriation by group members. When COA is low, traditional theories of TAM are replicated: both PU and PEU render high influences on our dependent variables. However, high COA mitigates the influences of PU and PEU, so that individuals of GSS are significantly influenced by the consensus of group members rather than make independent judgment upon the technical characteristics of GSS. In the mean time, FOA helps improve the task performance from GSS use, but does not moderate the influence of GSS use on task performances. This finding concludes that GSS use has an absolute and additional influence in improving task performances onto the independent influence of FOA on task performances.Our study proves that TAM does not provide paramount explanation about the adoption, use, and success of information systems beyond the individual levels. Our study is an early effort to combine different level of theories and develop a hybrid theory to provide a comprehensive insight over individual adoption and use of information systems in a group or organizational context.
