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.

The Agile methodology is a new trend in software development. Nowadays enterprises have been adopting the agile methodology in an effort to deal effectively with rapidly changing user requirements. In most cases, much improvement was accomplished in the software development. Some studies have mentioned that the motivation of software developers is a contributing factor on the improvement. However, it is not known yet what aspects of the agile methodology get them to be motivated. The aims of this study are the comparison between the traditional methodologies and agile methodology and look into potential motivation of software developer and their jobcharacteristics. For the empirical analyzing, research data were collected by 77 developers of 4 domestic IT companies. The analysis shows that there is significant differences on developer's potential motivation according to what kind of methodology is used. Agile developers to be more motivated than others methodologies developers. It also shows in detail that what kinds of job characteristics of developer are different among them depending on methodologies.

To develop of a new software, software development methodology is offering the most efficient development methods and management methods. But, it require a lot of time, cost and software engineering specialist. For this reason, we are awaking to the need of it, but it has its problem that is only applied to large-scale software. In this paper, we suggest optimized software development methodology that you can apply to a lot well-used small software development methodology in present, and we prove it through AHP(Analytic Hierarchy Process). This helps small and business not to introduce specialist can efficiently develop and manage software.

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.

Agile software development methodology has been implemented by software industries over a decade ago and well accepted in the practitioner community. However, there is limited understanding on how agile practitioners aware towards implementation of agile practices in software development. Lack of awareness will lead to misunderstandings among agile practitioners and misuse the agile practices. In order to understand the awareness of agile practices, this paper aims to investigate the factors that affect awareness of agile practitioners in implementing agile practices. A systematic literature review (SLR)was conducted in order to classify and define the factors of awareness in agile software development methodology. The review was based on papers between 2002 and December 2014 from seven electronic databases. The relevant papers were included 20 journal articles, 24 conference papers,16 book chapters, 9 workshop papers. Consequently, 69 papers were identified that closely related with awareness in agile software development methodology. From the thematic analysis, 13 factors were classified from 42 elements. Based on the review result, understanding the influential factors on the awareness of agile practices will provide benefit to researchers and agile practitioners.

To develop high-quality software systems satisfying the customer's needs, user-centered design (UCD) process has been emphasized in the area of human-computer interaction. And component-based development (CBD) has been extensively studied to realize a systematic software reuse, thereby reducing the time-to-market and the development cost. Balanced integration of user-centered design process and CBD process will be a promising way for successful software construction, which effectively achieves three goals: the quality of software, the cost of software development, and the time-to-market. However, traditional CBD methodology seems to lack the concept of user-centered design process and the relevant methods. This paper proposes a way of incorporating user-centered design process into a CBD methodology. Firstly, this paper gives the brief introduction of UCD. Secondly, we explain typical UCD activities and methods along the phase of systems development lifecycle and propose the use of usability maturity model (UMM) for integrating UCD activities and methods with those of CBD methodology. Finally, as a case study, we describe the results of comparing the UCD activities to the activities of MaRMI-III, which has been developed as a CBD methodology at ETRI.

Recently, concepts of the Fourth Industrial Revolution technologies such as artificial intelligence, big data, and cloud computing have been introduced and the limits of individual or team development policies are being reviewed. Also, a lot of latest technology source codes have been opened to the public, and related studies are being conducted based on them. Meanwhile, the company is applying the strengths of the open source software development methodology to proprietary software development, and publicly announcing support for open source development methodology. In this paper, we introduced several software development methodology such as open source model, inner source model, and the similar DevOps model, which have been actively discussed recently, and compared their characteristics and components. Rather than claiming the excellence of a specific model, we argue that if the software development policy of an individual or affiliated organization is established according to each benefit, they will be able to achieve software quality improvement while satisfying customer requirements.
