  • Over the past decades, there have been numerous studies for approaches to build and operate electronic government systems. Among those studies, work breakdown structure(WBS) has been gained attention increasingly. As a general system engineering techniques. WBS is a kind of methods to engineer and manage electronic government systems effectively. WBS is to organizes tasks and data items for management and engineering for electronic government systems. In this paper, the authors proposed a conceptual WBS model for management and engineering electronic government systems. Also, the authors conducted a case study based on the conceptual WBS model. The results of this study provide useful insights and guidelines for applying the WBS to management and engineering for electronic government systems. The authors believed that the conceptual WBS models will be widely used to management and engineering an electronic government systems.

  • Over the past decade, the topic of work breakdown structure (WBS) has gained an increasing amount of attention from information technology professionals as an effective tool for managing the complexity of a large-scale information system development project. It is a method for planning and controlling a large-scale information system development. A WBS provides the basis for project organization, cost estimation, task scheduling, and contract management. Based on the authors' practical experience, this paper discusses how to establish a specific WBS and some considerations for developing a well-defined WBS. The model of WBS suggested in this study will provide useful insight and guidelines for establishing the spec-ific WBS for a large-scale information systems development.

  • Work breakdown structure (WBS) can be used as an information center in earned value management system (EVMS) for the construction project. Because EVMS results, such as schedule variance and cost variance, are analyzed for the selected WBS code, the role of WBS code is important in EVMS. This study suggests a methodology for organizing WBS map with a quadrant. It can represent the project organization collectively by work level in a coordinate system. And the study developed an EVMS tool based on the WBS map and this tool can visualize various attribute indexes of EVMS by color symbols. Those methodologies can be used for improving practical application of EVMS.

  • Development of construction project management information system is accelerated because information management system has become more important by recent complicated and large-sized construction industry. There are many problems to operate PMIS efficiently because no standardized WBS exist in current. This study has identified the problems of WBS in building construction of multi-family house projects with 4 public and private organizations by interviews and compared each WBS. From those facts, this research presents the integrated WBS and the improved application form in PMIS.

  • The government abolished the existing method to calculate the construction price by the quantity take-off and pricing. It has introduced a new estimating system which uses the actual cost data on the basis of actual contract unit price. However, in the case of the current method to calculate the estimate price of BTL educational facilities, it is difficult to prepare an accurate ground for calculating unit prices due to a lack of standardized work breakdown structure (WBS) and guidelines for the detailed bidding documents. Thus, this research aims to establish WBS using the actual construction price on the basis of the actual bidding documents for the previous construction of BTL educational facilities. This specific WBS can be differentiated from the general WBS which is not suited for construction of the educational facility. It makes possible to build the construction information classification system and it helps to systemize the maintenance and repair cost items.

  • This paper discusses WBS (Work Breakdown Structure) that is known for technique of basic project management. The WBS use in domestic industries often exhibit errors in Its structure. The most common serious error is space-oriented breakdown structure of PBS (Product Breakdown Structure) that becomes the core element of the WBS. This paper proposes a method to correct the problem of space-oriented breakdown structure constructed in domestic railroad industry. DSM method was adopted to construct PBS containing function-oriented structure. The proposed process and method will contribute to minimize time that take to construct an accurate and useful PBS.

  • The schedule management in construction project have been performed independently by two method, WBS base management and CBS based management, However, the integrated management model is needed according to efficiency of construction project management and introduction of new EVMS system of KOREA government. For this purpose, interworking database system is designed through efficient modeling of WBS based management data and CBS based management data and relation establishment between entities in this paper. WBS based management DB consists of 4 entities and CBS based management DB consists of 3 entity and one of the 4 WBS DB entities is used to play interworking role between WBS and CBS, Also, attributes of all entities are well defined so that data consistency, integrity and newest are guaranteed. The designed interworking database model was realized using Nex-Pert Pro and the efficiency of data interworking was proved.

  • National construction project for SOC(Social Overhead Capital) is led by the government and invested high cost and all capabilities for long times. In general case the life times of SOC facilities are permanently. According to the long life time of the facilities documents and records of national projects are also retained permanently. Consistent classification systems are required to operation and maintenance of the facilities efficiently and to support the organic co-works for several Stakeholders. Therefore the classification of national construction projects are based on WBS of the project. WBS is the hierarchy structure that established and developed in project management project management methodology to produce deliverables of the projects. As a result, this study provides a prospect of project records classification systems in the 21st Century.
