Information System Synergy Governance Theory And Its Application

After entering into the information era,Information System(IS) is able to comprehensively support the production and management of enterprises,and the enterprises begin to know about the role of IS in the survival the development of enterprises,so more and more enterprises increase their invest in IS projects.But,the enterprises is alarmed to take cognizance of the risk of IS investment and be cautious to IS projects by the debate whether the"IS Paradox"exists or not and the cases about the enterprises turning to bay only for the failure of IS.Therefore,how to increase the successful rate of IS projects and how to maximize the IS value are the key issues during enterprises implementing IS.The Information System Synergy Governance Theory put forward in this dissertation provides the enterprises a new idea and a new method to optimize their IS implements and improve the actualization of IS value.This theory focuses on IS Synergy,and points out that the synergic action between IS and enterprise resource is the condition of obtaining IS value and the synergic effect from this synergic action is the source of IS effect.Governing IS Synergy is a necessary way to improve application effect of IS and obtain more IS value.The main contents and the creative points of this dissertation are as shows:A.Analyze deeply the necessity and feasibility of IS synergy governance,based on Synergy Theory,Information Entropy Theory,Competitive Advantage Theory,matrix operation and the analysis of evolution of the attitude to IS.There are two creative points in this section,one is verifying the necessity of IS synergy governance by the definition of information entropy,another is verifying the feasibility of IS synergy governance by the evolution model of the attitude to IS.This section lays a foundation for the later research.B.Build up the frame of IS synergy governance theory.By analyzing the relative literatures,the dissertation confirms that there are five enterprise key resource elements: business strategy,organization structure,business process,enterprise culture,human resource,which are the main synergic objects of IS.And then,the dissertation analyzes the interaction between IS and each key resource element respectively,and confirms the conditions of whether IS can form synergic relation with such resource element or not. Based on these conditions,the governance measures about how to improve the synergic degree between IS and key resource elements are put forward.This section is key content of academic creativity of this dissertation.C.Set up a IS synergic governance evaluation model.The synergic degree between IS and key resource elements can reflect the degree of realization of IS value indirectly, so this evaluation model focuses on the IS synergic degree.This evaluation model, which is based on Entropy theory and other evaluation theories,shows the method to compute the sub-synergic degree between IS and each key resource element and the method to sum up these sub-synergic degrees to enterprise IS synergic degree.The evaluation model is both scientific and agile.This section is key content of applied creativity of this dissertation.D.Lastly,an enterprise is analyzed by IS synergy governance evaluation model. The analytic result,which accords with the actuality of this enterprise,shows the basic status of realization of IS value and the role of the measures of IS synergy governance in promoting the realization of IS value,and points out the direction for optimizing IS in the future.This case proves the evaluation model is valuable and universality.
