Risk factors are the reason behind cost overruns and delays in long-term large-scale IT service projects. Major risks originate from the integration of complex IT system components, including software, hardware, and solutions; the competitive bidding process; the turnkey and firm-fixed price nature of contracts; and the project execution environment. We have identified several risk factors such as delay in acceptance, low quality of deliverables, delay in payment, adding and changing requirements and scope, unclear definition of roles and responsibilities of the buyer and supplier, and unclear procedures of change and quality management during the project execution phase. One needs to manage risks proactively before signing the contract. In order to weed out or lower the risk factors well in advance, we need to identify and remove risk factors contained in contract clauses and attached contract documents. We propose a checklist for assessing IT service project contracts. To validate the checklist's utility, we applied it to an IT service project in the finance industry. The results show that the checklist is effective in identifying and removing risk factors pertaining to IT service projects.

Black-box testing needs to prepare fitting test data, execute software, and examine the result. If we test software effectively, not only selecting test cases but also representing test cases are important. In static testing effectiveness of testing activities also depends on how to represent test cases and checklist to validate. This paper suggests a method for finding ineffective critical test cases and reengineering them. An experiment of reengineering digital set-top box software shows the process and results of checking effectiveness and conformance of current test cases and patching test cases. The result shows how much save the test time and improve test coverage by reengineering test cases. Methods of reuse and restructuring test cases are also studied to fit into embedded product-line software.

International standard for software quality evaluation, ISO/IEC 9126 defines the quality characteristics and sub-characteristics consisting of quality of the software. Also, in this standard, the quality assessment items are presented in metrics based on maturity, fault tolerance, recoverability and compliance which are sub-characteristics of reliability. However, this reliability assessment items which are presented are not applied now due to the mathematical difficulties and the problems caused by collection of data. In order to resolve these problems, this study introduces measures to develop a specific test technique by quality attributes and to measure the quality. In other words, the detailed guidelines are presented to be utilized as a standard by summarizing test activities and techniques by each development life the most commonly used. The SW quality results are derived by assigning weights to software in order of the most important quality characteristics of respective software using checklist that can be easily utilized and applying test technique that can be utilized for detailed evaluation items and checklist. This improves problems that include reliability assessment item of ISO/IEC 9126 as the measures to measure new reliability quality of software.

This study discussed extensively the CD-ROM evaluation criteria that are necessary for library and information center to acquire the CD-ROM products. The evaluation criteria discussed in previous studies are divided into managerial and technical aspects, and especially the search software and user interface catagories in the technical aspect are investigated separately. Finally the basic checklist is suggested for the evaluation of CD-ROM product in appendix.

This paper proposes methods of evaluating and measuring accessibility of accredited certificate subscriber software which is one of crucial applications to submit personal certifications while web surfing. The presented methodology is to evaluate accessibility by using a certain assessment tool and is to normalize accessibility level into points, so that the software developers who are unfamiliar to screen readers can easily perform accessibility evaluation. The software from the major 78 organizations has went through the assessment. Those of 48 organizations, 62% out of the total, have acquired less than 70 points, implying the software of them is not accessible by the blind. The remaining 18 software got the highest point(88), are partly inaccessible by the blind that uses screen readers. This implies that the proposed methods are applicable to evaluate the accessibility of the software.

In order to enhance the productivity of mobile and develop reliable software, the test of mobile application software should be required absolutely. The most important way to communicate to users has been used to GUI. But GUI test method in mobile has no the test automation system except manual test by checklist. In this paper we present a test method and tool by image flow to reduce the time required and finds out errors to GUI, by carrying out the study on automatic GUI testing tool based on image flow to GUI test of mobile application.

This paper examines how a Computer Engineering Graduate student team ran their Advanced Software Engineering Capstone project using SCRUM. The environment provided contextual challenges in terms of the on-site customer and upfront requirements document, not uncommon in a document driven single-step methodology. The paper details the methodology and practices used to run the project, and reflects on some of the challenges faced by the members of a typical software team when transitioning to a SCRUM process. The paper concludes by evaluating the success of the techniques and practices compared to the Agile Manifesto and Henrik Kniberg's Scrum checklist. The project was undertaken at South Korea's Ajou University.

Based on the prior research which developed the consistency review checklist of the BIM model and 2D drawing through the drawing analysis of the construction documents phase, the apparent limits of the existing template and the template development items were derived. As well, the BIM-based drawing templates of the construction documentation phase were developed and verified using ArchiCAD BIM software. The developed template was then applied to the actual project model in the construction documents phase, and, as a result, 50% of existing work elements could be utilized as templates. This is an increase of more than 30% over the existing template utilization elements, and it is analyzed to be effective in practical application and utilization. Based on the results of this study, if the BIM model construction criteria matching the drawing's utilization purpose are presented, while at the same time the BIM data interlocking and drawing template development studies are conducted, the utilization of BIM data can be maximized and additional drawing work can be minimized to increase the percentage of template utilization elements. In addition, it is believed that this can employed to address functional and institutional problems of BIM-based drawing and make a contribution to the activation of BIM.

There are many defects when we're working on a project. Especially, if we don't have experience in similar field, defects have a strong influence on the system entirely. Therefore, management of risk such like defects is important the factor for success of project. Finally, efficient management of risk can guarantee handling problems such like fault tolerancy, unexpected quality and delay of schedule. In this paper, we propose checkpoint for improvement of reliability and are willing to improve the reliability of an entire system using it.
