  • The Post-Construction Evaluation and Management System has been operated over the past 20 years not only to analyze the performance of large-scale construction projects, and but also to provide useful reference data for future similar projects. Although the Post-Construction Evaluation and Management Center has been legally designated and operated since 2020, various problems have been occurring in the operation of the system. Accordingly, this study proposes strategies for facilitating Post-Construction Evaluation and Management System in terms of the following three aspects: (1) improving the implementation rate of post-construction evaluation; (2) improving the information management system related to post-construction evaluation; (3) improving the utilization of post-construction evaluation outcomes. Based on the results of this study, a specific action plan will be prepared, which is expected to contribute to the efficiency of construction project performance management in the future.

  • Post-evaluation system reflects the results of performing a public construction project in the future similar public construction projects to be utilized in the planning. However, the current system simply compares the expected values, such as demand, B/C ratio, cost of construction, construction period, with the actual values after the completion of construction. In addition, most public owner does not actively conduct the post-construction evaluation tasks, so that the evaluation results has not been returned to early stage of a construction project. In this study, status of the post-construction evaluation system is investigated by a survey of the public owner and the construction project evaluation system of the United States and Japan was analyzed. This paper presents the improvement scheme of utilization of the results of the post-construction evaluation system. Through improving the post-construction evaluation system, it is expected that public agencies would easily utilize the post-construction evaluation.

  • The purpose of this longitudinal case study is to shed light on the reliability problems of IS performance evaluation by analyzing the discrepancy between ex ante evaluation in 2011 and ex post evaluation in 2012. Through an information system development project of a public enterprise, the gap between ex ante and ex post evaluation was ascertained and the causes as to why such gap occurs and the success factors that can solve the problems were derived. The ex ante evaluation of IS performance was performed based on both IS success model and BSC model and the ex post evaluation was carried out at the time after the target system has been built up by applying the evaluation measures and process that are similar to the ex ante evaluation. In the ex ante evaluation the business performance improved by the target system was estimated to 18.2%. On the other hand, it was seen as being low at 15.2% in the ex post evaluation and the differences were found to be statistically significant in 6 out of 10 measures. The reasons as to why such gap occurs were diagnosed as being of 2 types : (1) changes in the evaluation psychology according to the differences in the evaluation objectives; and (2) excessive expectation levels of the target system that is formed at the time of the ex ante evaluation. In other words, the users who have excessive expectations tend to overestimate in the ex ante evaluation and, in the ex post evaluation, tend to underestimate lower than the actual performance mainly due to disappointment on the results that do not meet the early expectations. As solutions to overcome the reliability problem of ex ante evaluation, 3 factors were derived : (1) the temperance of excessive expectation levels of the users; (2) a clear definition of the scope and functionality of the target system; and (3) actual commitments for the evaluations of IT performance.

  • The purpose of this study is to investigate the evaluation perspectives of IT business value and empirically analyze the differences of evaluation perspectives between ex ante evaluation and post implementation evaluation, and among various information system types. 4 evaluation perspectives which have been used in the previous studies and in the field of industry practices are financial, customer, internal process, and growth, which are based on the BSC model. Data of 98 information systems have been collected from 89 companies including manufacturers, banks, insurances, and stock trading companies. As results of multi-way MANOVA test, 3 out of 8 hypothesis have been accepted statistically. While the order of importance of 4 perspectives in ex ante evaluation is customer, financial, internal process, and growth, the order of post implementation evaluation appears to be much different : that is, internal process, customer, financial, and growth. These findings provide insights for both IT practitioners and researchers.

  • In this study an evaluation method is proposed, with the strong relationship between the ante and post audit works evaluation. The ante evaluation does in general and systematic ways, with past audit results and proposals. The criteria-based evaluation is used for the audit activities and outputs. The critical success factors for the projects applies to the activities evaluation and product evaluation framework to the output. The ante and post evaluation have the cross evaluation items to be the whole and continuous one. Eighteen common evaluation items are derived, with their own evaluation elements in detail, which have only differences of the actually done and expectations between the ante and post. The proposed evaluation makes the ante and post one to be related with each other in a systematic and objective ways, to enhance the reliability of audit results and effectiveness of the audit.

  • Postmortem evaluation through the dictionary and the lack of points for the wrong strategy to respond to the avoid the prediction is important. However, the prevailing system of ex post facto assessment of postmortem simply does not have statistical figures to be provided only for the conditions. Thus, in this study, rail business is mainly evaluation procedures and evaluation of the verification system of ex post facto evaluation as to the issue, do not improve.

  • The post-evaluation system after construction projects can evaluate estimates of use demand, project cost, and project schedule estimated in the planning phase of construction projects in public sector. Thus, it was introduced in 2000 for the purpose of reduction in future errors during similar constructions by project orderer by referring the post-evaluation results. However, many barriers to the post-evaluation system after construction projects have been reported due to evaluation systems that lack objectivity and reliability and lack of main bodies that utilize the system. Thus, this study derived implications for improvements of the post-evaluation system in Korea by benchmarking building project evaluation system and management as well as utilization systems of developed nations. Then this study conducted a survey with experts who have experienced activities in the post-evaluation committee and members of post-evaluation for public project owners. Therefore it identified the need of installation of specialized post-evaluation institutions as well as functions and work tasks to be taken by specialized institutions. Based on the analysis results, this paper provided revision drafts of related legislations and guidelines to be effective in post-evaluation. Through the study results, many trial and errors can be reduced in similar projects in the future by performing in-depth analysis on large-scale construction projects and repeatedly applied building project practices can be improved to raise technical competitiveness if the specialized institution is installed.

  • A diverse rural development projects are continuously increasing. However, in most villages, the business run by residents is not being operated normally. Followed by these problems, a follow-up management evaluation system has been created and utilized, but the existing evaluation system is only administratively approached and not suitable for application in reality. This research emphasizes that the perspective of community and re-startup support should be added to the evaluation system as these are projects that are carried out to improve the quality of life of local residents and enhance the rehabilitation of villages. Based on the evaluation system proposed in this study, field surveys and interview surveys were conducted targeting 10 villages in Taean-gun, Chungcheongnam-do in South Korea. As a result of the study, various types that have not been activated were derived, and they were presented by categoriz ing them. The purpose of this study is to help the rehabilitation of common rural villages by providing a updated post evaluation system and items that can be applied not only to Taean-gun but also to numerous villages in the entire villages in South Korea.
