This paper analyzes the effect on productivity by measuring Function Point per MM(man-month) in a software development project and code inspection which performed in Agile methodology, and introduce the method of applying MDA/MDD technology in the e-government standard framework project. MDA/MDD which recently raising its head is technology that increase software development productivity through automatic transformation form abstract model into lower abstract model, or from model to code. but, many Lessons obtained through the case studies, the analysis suggests a limited effect measurements. In this study, efficient development methodology and utilizing a e-government framework to measure the effectiveness of the MDD to the new measures through a case study applied to real information system development process. In addition to, managing information modeling through integrated repository presents a traceability and visibility.

In this paper, we will present brief design feature, implementations, and tests for verification of KOMPSAT-2 simulator, which is a subsystem of KOMPSAT-2 MCE. SIM is implemented on PC server to minimize costs and troubles on embedding onboard flight software into SIM, OOA/OOD methodology is employed to maximized S/W reusability, and XML is used for S/C characteristics, TC, TM and Simulation data instead of commercial DB. Consequently, we can reduce costs for the system, efforts embedding flight software, and maximize software reusability. SIM subsystem test was performed successfully.

ATC on-board equipment require realtime embedded software with high level of safety and reliability. To satisfy these requirements, many techniques are applied to the development of software during the lifecycle. In case of software modeling, object-oriented methodology is widening its niche replacing traditional structured methodology and modeling in UML using a CASE tool is a growing trend. In this paper, we modeled ATC on-board software in UML using Rhapsody, which is a modeling tool for realtime embedded software. We modeled the behavior of ATC on-board equipment based on state machine diagram and validated the model using the animation feature provided in the tool. According to our study, the CASE tool based on UML showed high level of applicability in modeling and verifying the software with complex behavioral characteristics.

Though any method in various software development methodology is selected and used in performing IT project, there are quite a few problems in applying it to the project environment, thus customizing effort as a reasonable method is continuously demanded. Therefore, the study attempted to track a basic frame formation process of quality management model applying the software development methodology based on SDLC that is widely used. The study analyzes and modelized an empirical cases of a financial company that is relatively highly rated by expert groups through a variety of trial and error and continued supplementation for it for a long time. And in addition to it, it analyzes cases of public institute project, derives problems, and also proposes a guideline related to creating artifact.

The various software engineering techniques have been appeared in order to cope with the software crisis since 1980's. Currently, the research against the techniques likes the Design pattern, Component which improve the software's re-use are spread out. Also S/W Development Process are interested intensively which attempts the quality and a increasing productivity of software development with the basic policy. The design pattern is the solution against the problem which occurs repeat in a specific area. Many design pattern are developed and researched, but the method which accommodates the developed design pattern efficiently in the phase of analysis and design software development process is not good enough, so it is the actual applying technique is difficult. In this paper we suggest and the “UML components+” which is a efficient component development process from customizing EJB based the J2EE using the “UML Components” which is a component development methodology. Applying J2EE pattern efficiently with UML components+, there is a possibility of efficiency in the component development based pattern.

Component-based software development (CBD) is a methodology that has been embraced by the software industry to accelerate development, save costs and timelines, minimize testing requirements, and boost quality and output. Compared to the conventional software development approach, this led to the system's development being completed more quickly. By choosing components, identifying systems, and evaluating those systems, CBSE contributes significantly to the software development process. The objective of CBSE is to codify and standardize all disciplines that support CBD-related operations. Analysis of the comparison between component-based and scripting technologies reveals that, in terms of qualitative performance, component-based technologies scale more effectively. Further study and application of CBSE are directly related to the CBD approach's success. This paper explores the introductory concepts and comparative analysis related to component-based software engineering which have been around for a while, but proper adaption of CBSE are still lacking issues are also focused.

Experimental software datasets describing software projects in terms of their complexity and development time have been the subject of intensive modeling. A number of various modeling methodologies and modeling designs have been proposed including such approaches as neural networks, fuzzy, and fuzzy neural network models. In this study, we introduce the concept of the Rule-based fuzzy polynomial neural networks (RFPNN) as a hybrid modeling architecture and discuss its comprehensive design methodology. The development of the RFPNN dwells on the technologies of Computational Intelligence (CI), namely fuzzy sets, neural networks, and genetic algorithms. The architecture of the RFPNN results from a synergistic usage of RFNN and PNN. RFNN contribute to the formation of the premise part of the rule-based structure of the RFPNN. The consequence part of the RFPNN is designed using PNN. We discuss two kinds of RFPNN architectures and propose a comprehensive learning algorithm. In particular, it is shown that this network exhibits a dynamic structure. The experimental results include well-known software data such as the NASA dataset concerning software cost estimation and the one describing software modules of the Medical Imaging System (MIS).

In this paper, a model of cost evaluatino for computer software development is proposed . This model is designed to cope with various development environment since the development cost is directly dependent on the development environments. The model that satisfies the users request is turned out to be a function point model. For the future research , a model that contain new technique and new development environment and an imaginative model are desired . Also, in order to effective cost estimation a systematic research on structure of software development , establishment of standard development methodology, project management and technique are desired.

Many IT organizations aspire to improve the efficiency and general standard of their software development effort by implementing agile software development practices. Some of the popular agile development methods adopted by IT organizations are Scrum, eXtreme Programming (XP), Kanban, Featured Driven Development (FDD) and Dynamic System Development Method (DSDM). This paper intends to identify and analyze the barriers that impact on the performance of IT organizations that use such agile software development methods. The analysis will help the IT organizations to cater the needed aspects to be successful. The analysis will also help the IT organizations to select the right methodology for their organization. The contribution of this analysis is to present guideline related to avoid or overcome the barriers towards adoption of agile.
