조직의 ITA/EA 기능이 IT 거버넌스에 미치는 영향 = (The) Influence of the Organizational ITA/EA Functions on the IT Governance

다국어 초록 (Multilingual Abstract)

This research covers the possible influence to IT Governance infrastructure to organization by various effect and function of ITA/EA. Also, provides corroborative verification of differential of influence based on character of organization by effects of ITA/EA. Recently, the government, public organization, Private Corporation, bank and Insurance Company are in preparation to have major informationlization and consider to participate on ITA/EA and IT Governance.
With the efforts by government and NIA(National Information society Agency), the concept of ITA/EA has been in the thesis stage but in the result of research shows that 33.6% of total is planning to adopt the ITA/EA, 68.1% of total are in 1-2 stages to recognition and form of formation, and 22.7% are in 3 stages to developing stage. As it indicated total of 90% are either in developing stage or recognition stage. Also for the consideration of IT governance, it's not even in forming stage of getting a concept.
Due to the lack of execution on research of ITA/EA, developed the research variable by using all the capabilities and effects from domestic and international references to come up with 24 categories and to tie up to four (4) major sections. Also with various lead on definition and field of IT Governance, gather around all the categories from existing research data and organization to put into five (5) major sections to developed the research variable. Therefore, with survey and analysis procession the developed variable determined categories, it regrouped to five (5) kind of ITA/EA's function and three (3) kind of IT Governance. Thus, some of categories came out to be differently than what it predicted originally. However, organically the research was focus on factor analysis, appropriate analysis and reliability analysis of the presented article and the result came out to be exceed the point of reliability, it required continuous research with modified research model. It actually formed to new research model after include regulation variable and add new variable to the topic.
After the verified result on new research model, it indicated the adequate statistical point led to function of ITA/EA could apply the affection to IT Governance. Therefore, when ITA/EA needs to be measured, it arranged in order of importance of IT integration, Infrastructure systemization, IT alignment, improvement on effective use of resource and efficiency of investment. With this sequence, the influence are effecting to IT Governance.
When the concept of IT Governance is limiting and effecting by function of ITA/EA, the arrange of importance are management of IT resource ＆ result, management of IT project, and management of IT service.
Also, the result provides a statistical differential based on the type of organization whether it's a planning type, performance type, and mixed type.
This research offers the following results.
First, on function of ITA/EA originally arranged with 20 types of specific function, the result of this research developed to five (5) type of positive variable with evolution management of IT resource, Infrastructure systemization, effect of decision-making, improvement on effective use of resource and efficiency of investment.
Second, with various lead on definition and field of IT Governance, gather around all the categories from existing research data and organization to have three (3) types at the result of this research, which are management of IT resource ＆ result, management of IT project, and management of IT service.
Third, the research verified the positive answer that focus on ITA/EA could gives infrastructure to establish the IT Governance.
Forth, based on business type of organization, the function of ITA/EA has different effects to establish the IT Governance.
To summarize the result of this result, the ITA/ EA ＆ IT Governance are very popular in informationalize field and this research is indicating that the successful adoption of ITA/EA will benefits to establish the IT Governance. Also, it gives meanings to the territory of function of ITA/EA and IT Governance that were developed based on environment of domestic market.
But the this research might has limitation due to the possibility of leave out partial categories from using all the capabilities and effects from domestic and international references and possibility of leave out few other kind of field on character of organization even efforts to cover most of different organization.
As it indicated in above, the more organization shall need to adopt the ITA/EA and operating of IT Governance. Then more detailed and research should be achieve based on the reference and experience. Hope this research could bring the foundation to have continuous research on ITA/EA ＆ IT Governance which are the foundation to informationlization.
