In maintenance and operation of information system, it is extremely difficult to crimp operation mistakes and troubles completely. Program developers and maintenance operators have modified cause in case of trouble, and have improved feedback on review, however, mistakes and troubles have still occurred. Besides, we have gone to a great deal of trouble to post handling and explaining to client. As for countermeasures, we made use of tree diagram, matrix diagram, 5 Whys analysis, and Mind Map[○!R] etc, we couldn't determine proper root cause, because most of members included offshore members haven't experienced enough quality management. Therefore, we used SCAMPER, which are new-products development and the method for idea, and then devised "SAFETY Framework". This is the method to consider countermeasures of compulsory association in IT service management. In addition, it is available if members wouldn't have any knowledge about quality management and experiences, so I make a suggestion below. This paper shows a way of thinking about "SAFETY Framework" and an improvement example of maintenance and operation to which "SAFETY Framework" is applied.

In late years the quantity of ordering of the Offshore Development increases, and it becomes important that we manage the project quality appropriately. One of the points to divide the success or failure of the project is "Bridge SE", but the examples "that a user company orders from a directly overseas IT vendor without using Bridge SE" begin to appear in these days (I call that "Direct Offshore Development" as follows). In this report, I mention a risk and measures of the Direct Offshore Development, and I report the case study that Tokio Marine & Nichido Systems tried the application by Direct Offshore Development in Vietnam.

Recently Japanese companies have been moving into overseas more actively than before. In such a case, systems construction and operation support for their overseas business has been mainly conducted by overseas bases. However, there is the gap about quality management between Japanese customers and local system integrator in overseas. Two factors cause the gap. One is about Japanese management approach. Another is about mind for quality improvement. Therefore, we conducted management training because we considered that it is necessary for local staff to understand Japanese management approach correctly and instill it into their business process. Furthermore, we included some of case studies in the training so that participants can take in others' idea as their own knowledge by combining self-learning and discussion. As a result, this training has affected change of working approach and activation of quality management for local people. We believe this activity will contribute to improve system quality and lead to success of many projects.

Nagoya University has tried to design the evaluation criteria to manage reliability of the Nagoya University Information Environment according to the Nagoya University's Strategic Plan 2010 for Information Environment. Although the reliability evaluation index for services levels has been developed, the continuity criteria of service operation projects had not been developed. In this paper, 67 indices to evaluate service continuity of operation projects can be designed based on IT service continuity management description of ITIL. A case study to introduce the criteria and evaluate the continuity of 13 services is also described.

With the advancement in Information Technology (IT), software industry has made significant growth over the past years. Nearly all companies are using some kind of "IT systems" to do their business. Those systems are aimed to the have all the functionality designed, as well as to able to meet the quality attributes such as reliability, usability, maintainability and so on. However, during the last few decades, few improvements in the quality of software is observed. While QCD is critical to all projects, the "quality" attribute is difficult to quantify and has often been disregarded. As a result, delay of the service happened when system performance problem arise, loss of business opportunities due to the sudden stop of the system, and worse of all, even lives and properties are endangered due to malfunction of the systems. To most companies, it is a major challenge to improve quality with limited cost. While some of them spend a good portion of cost on testing, they are not getting the results they expected. According to our research, many of these systems are not having their test done correctly, and in some cases, they cannot even create the test cases from the specification for testing. In this paper, we first revisit static testing. Then we make a discussion focus on "testability" and show how can we improve the testability of the system and create test cases from documents of the upstream development process such as requirement definition documents and design documents.

Risk-based testing is the technique that quantifies risks of functions and attributes under test to reduce test cases reasonably according to the risk degree. However, there is a possibility that if risk assessment ends in failure it lead to bad quality by reducing test cases. So we considered the method to evaluate validation for risk assessment in a statistical way such as multiple regression analysis. Then we applied the validation method to an actual project. We summarized its efforts in this paper.

With the slowdown of enterprise IT spending, it is getting harder to win a new system integration contract. In order to reinforce the relationship with an existing client and secure business opportunities, it is essential to deliver satisfactory maintenance services after a systems delivery. During the long term maintenance phase of a large scale system, your client is supposed to request various system improvements, which may spread from a simple functional change to overall transformation. However, the human resources should be minimized due to severe cost reduction pressure from the client. In many cases, a limited number of experts maintain the whole aging system, which often causes human errors especially in analyzing the impact of the system changes. In order to ensure the service quality, you must grasp all the client requirements and their attributes, and comprehensively manage them. This approach will enable appropriate resource allocation and suitable risk management. It is also effective to redefine and visualize all the work process, which may have been obsolescent during the long maintenance phase, to avoid excess dependence to the individual skills. In the reference case in this report, we redefined the upper process of the system improvements. For "Requirements Definition Phase", consistent criteria were developed to identify the attributes of the requirements, and a guideline to determine quality assurance level based on the attributes. Furthermore, "Impact Analysis Phase" and its work process were newly created to track how the impacts were judged based on what input. In this case, the appraisal of the service quality was drastically improved. The approaches introduced here are reusable in terms of how risk and impact could be visualized for evaluation, and will be good references for any organization which provides applications maintenance services.

From the 1990s, most companies adopt the ERP package when they choose the financial accounting system. The account data which are dealt with the ERP packages are managed as a lot of master data. These master data are one of the important properties of the company, and it is necessary to manage them appropriately. This kind of management method is called MDM (Master Data Management). In this paper, we will introduce a case study which is we are determined the cause of problems which is occurs in the dealing with the master data and the subject which is the quality improvement activity.

This study proposed a method to visualize the risk structure using FTA (Fault Tree Analysis) as a time-dependent fault tree (TDFT) for quantitative project risk management considering the project time factor. The project risks are characterized by a risk relationship structure and an occurrence mechanism comprising the cause, risk event, and effect. The project risks are not stable; rather, their occurrence probability and importance change with the project progress. The project manager should consider risk's status and its structure for the adequate actions in a timely manner. Therefore, there is a need for a method to capture the risk structure and its changing status. Hence, this study proposes a quantitative method for structuring the project risk using TDFT. The proposed method enabled project managers to manage the project risk by visualizing the risk structure and quantitative evaluation using the TDFT, and monitoring the status using the project risk control chart. The feasibility and effectiveness of the proposed method were verified through a case study.
