It will be more constructive to probe how to create and achieve information system(IS) value than todiscuss whether IS will return value to firm's investment. The realization of IS value is impacted by various factors, it will be very helpful to evaluate and control the IS realization process and impact factors in the full cycle of IS building. The traditional IS value management research is facing three problems include: short of systematic IS value realization process and factors analysis, excessively monopolized method and lack of maneuverability. It's very difficult to satisfy the practice requirement of IS buiding management and IS value creation.The practice of Information system(IS) building management presses for one holistic IS value management system, which could selelct various actions and methods under a unitive value and principle to facilitate the achievement of IS value.But Aimed at these three problems, this dissertation presents a holistic assistant system that considering IS value realization impact factors ,IS value management theory, and IS evaluation et al solution, which named as "Evaluation based Active Value Realization(EAVR)" model. Combined with IS full cycle building management, this model can actively facilitate and guarantee the achievement of IS value.Follow up the research route "Concept-theory-methodology-method", EAVR research is firstly rooted in the literature review of IS value management and evaluation, then making the three problem of IS value management as the breach point, analyzing the IS value and its achievement impact factors before setting up corresponding IS value management system. This system then is combined with IS full cycle evaluation and project management framework to be put forward as the formal and comprehensive "EAVR" Model, the succeeding is the detail introduction of EAVR's application method. Finally, this paper adopt DEA to validate the EAVR's contribution to IS value realization process through ten cases' data, and explain the different IS results of two cases by EAVR theory. The innovation point of this dissertation can be concluded as: Introduce the concept of value management into IS building management, integrate various brilliant but dispersed IS management methods into a holistic theory framework to improve the IS realization degree together. Put forward the detail connotation and components of IS value ,analyze the IS value achievement process and conclude the key factors that impact the achievement of IS value and demonstrate its effectiveness. Bring forward IS value management system contra posed the IS value achievement impact factors, and combined with IS full cycle evaluation and project management framework to form an IS active value realization model to assist IS project management. Apply DEA theory to construct the evaluation model of IS building process effectiveness, and manifest the active influence of EAVR activities to ultimate IS value achievement.
