A methodology is often used in solving complex problems. As a typical case of complex problem solving, development of information systems mostly requires a use of system development methodology. However, it is not always easy or smooth for organizations to adopt the methodology and to achieve a positive outcome from their application in real project situations. Although there are a few studies to find out success factors in the implementation of the methodology, they did not take into consideration essential characteristics of the methodology. This study aims to analyze the quality of the methodology as a key determinant to influence the performance of the methodology application.

Research issues in software engineering in recent may be object oriented methodology and software quality. Since Halstead has proposed metric-software science in 1977, software quality area has been studied in steady but inactively until 1980s. As international standards such as ISO 9000-3, 9126 were enacted in 1990s early, interest in software quality is increased but many problems such as how to validate metric, measure quality or apply metric are remained. This paper proposes software quality metric methodology which software developer or project manager can use in measuring quality and validating metric during software development. The methodology is classified by several phases: establishment of quality requirement, identification of quality metric, data collection, metric implementation, metric validation. In order to show its applicability, test program, metrics and data are applied to each phase of the methodology. Consideration of this methodology as a methodology for software quality measurement similar to development methodology for software development is needed.

Quantitative methodology has been the predominent methodology utilized in research in nursing. However since the 1970s qualitative methodology has also emerged as a useful methodology and has been utilized by many researchers. But in the use of this methodology, the philosophical, epistemelogical, and theoretical backgrounds have been neglected by many researchers. This paper reports a review of the literature on methodologies, quanitative and qualitative, used in nursing, and makes suggestions for future research directions. It explains why qualitative methodology has emerged as as effective methodology in nursing and discusses how the qualitative methodology differs from the quanitative one. A comparison of the two is made based on perspectives of humane being and human behavior as well as the development of nursing science. This paper also presents several views on change in nursing science, since viewpoint not only influences the determination of the current stage of nursing science but also the shaping of the future directions of nursing science and research. Scientific revolution by Kuhn, the evolutionary perspective by Toulmin, the transition of research tradition by Laudan. and convolutionary processes are presented. However, this paper indicates that it is too early to adopt these points of view, because the history of nursing science is too short. It suggests that nursing needs pluralism in philosophy, paradigms and theory, as well as in methodology. Although we experience paradoxes in adopting different perspectives in nursing, it is wise for us to continue to include a variety of viewpoints including those to which we are not accustomed, such as qualitative methodology, since we are not yet able to decide what is best for the development of nursing science.

Our study focuses on the implementation of IS development methodology as the innovation of IS organization. We have two main research objectives. We Intend to understand the critical factors affecting the implementation process of IS methodology. We also intend to deeply analyze the relationship among the implementation processes of methodology. The whole innovation process is divided into detailed four levels tilth dynamic and evolving Point of clew a cognition level, an adoption level, an acceptance level and an usage level. The results of our study are as follows. The main factors affecting initiation level of the IS methodology are the innovativeness of IS members, the existence of champion manager, training, the existence of IS performance gap, executive supports for IS organization, and the relative advantage of IS development methodology At the Implementation level, It is understood that the existence of champion manager executive supports, training and the relative advantage of innovation are the main factors. However, the complexity of Innovation is a megative factor about the quality of accepting and using the methodology In Innovation process. In performing the Innovation process, the Previous level gives very notable affection to the continuous next level. However it's also understood that positive attitude of adoption level does not directly affect the quality of using Innovation. Therefore, IS managers must pay attention to manacle each level of the Innovation Process to successfully accomplish the Implementation of IS methodology.

The software development methodology has not caught up with the rapid change of information technology. Most of the software development projects use structural methodology or information engineering methodology. If established software development methodologies don't reflect technologies applied to the project, the project may be performed ineffectively. This paper describes a model in which we can apply a new information technology to an already existed structural methodology or information engineering methodology. This model uses the technique of the divide and conquer that software development life cycle is divided into phases, each phase is divided into viewpoint- areas and the software development processes of a new information technology are applied to each small area. By using the design phase this paper shows application example, in which I applied web-based development processes to CS@RoadMap Methodology of KCC Information & Communication, a system provider in Korea. The CS@RoadMap Methodology reflecting the Web technology, Web@RoadMap Methodology, has been applied to the public-domain projects.

The market size of Internet portals has been continuously expanded and also competition has been fierce. For the business success of Internet portals, it is necessary to repeatedly perform a renewal project which improves their services, reflecting more improved or changed strategies. Accordingly, this paper proposes an analysis methodology for performing the renewal project more systematically and effectively. The methodology consists of four phases : establishing improved strategies, analyzing customers, deriving service alternatives, and determining services. The methodology places an emphasis on reflecting effectively customers' standpoints (i.e. customers' needs) and service providers' standpoints (i.e. business strategy) upon service improvement. Furthermore, the methodology includes a specific technique for analyzing the feasibility of services. To demonstrate the practical usefulness of the methodology, a real-life case is illustrated.

A simplified statistical methodology is developed in order to both reduce over-conservatism of deterministic methodologies employed for PWR fuel rod internal pressure (RIP) calculation and simplify the complicated calculation procedure of the widely used statistical methodology which employs the response surface method and Monte Carlo simulation. The simplified statistical methodology employs the system moment method with a deterministic approach in determining the maximum variance of RIP The maximum RIP variance is determined with the square sum of each maximum value of a mean RIP value times a RIP sensitivity factor for all input variables considered. This approach makes this simplified statistical methodology much more efficient in the routine reload core design analysis since it eliminates the numerous calculations required for the power history-dependent RIP variance determination. This simplified statistical methodology is shown to be more conservative in generating RIP distribution than the widely used statistical methodology. Comparison of the significances of each input variable to RIP indicates that fission gas release model is the most significant input variable.

Information strategy planning (ISP) pursues alignment of business strategy and IT (Information Technology) strategy as well as derivation of feasible and valuable IT projects. However, conventional ISP methodology hardly obtains the objectives because of its intrinsic shortcomings. Diverse ways are proposed for the improvement of the conventional methodology including, for example, combination of EA (Enterprise Architecture) with ISP. Meanwhile, six-sigma methodology which is characterized by quantification, scientific and systematic approach, customer orientation, process orientation has been gaining considerable attention and extending its application scope continuously. In this paper, an innovative ISP methodology is proposed by decomposing activities, methods, and tasks from conventional ISP process and reorganizing them into DMADOV six-sigma framework. In addition, the usefulness and applicability of the newly proposed methodology are provided using an electronics company example. The methodology enhance the possibility of producing future oriented and beneficial IT projects by associating IT strategy and the projects in the form of quantified causal relationship. Besides, it can also increase the objectivity of IT vision and strategy.
