This paper verifies the effectiveness of system engineering by its impacts towards enterprise system generation. An industrial case studies is presented about IBM adopted a model-driven engineering method to determine intentional services that meet business goals. It aims to extend the understanding of a specific method of system engineering- Service Oriented Architecture (SOA), with its flexible integration of business process and effective simplification of generation framework. Besides, system engineering tool is also proved to benefit asset collection for enterprises in fashion industry, with Service Oriented Computing (SOC) applied, along with integration of wireless sensor networks framework. In the last, several specific methodologies are also implemented to demonstrate the examinations and assessment ways of the proposed approach, supporting how system engineering provides a practical approach to balance all needs, satisfying enterprise operators, and benefit the system operation throughout the life cycle, not a single tool used for demand analysis.
