To develop a dynamic system project in which the requirement changes frequently, it's impossible to finish the development within a fixed-cost due to additional budget occurring in need of requirement creep. To manage the successive project within a fixed-cost, it's better to manage the ratio of necessarily changed size of project and necessary optional requirement. According to Bhagwat, it is occurred in the construction phase. Also, he stated that the software development cost, construction phase cost and requirement cost are equal and it was wrong explanation in the ratio of requirement creep and optional requirement. This paper assumes the requirement creep to be happening in the phase of elaboration and construction. In addition, some differences were supposed to happen between software development cost, construction phase cost, and requirement creep cost. As a result, the reality was preferred rather than the ratio of optional requirement and the ratio of requirement creep.

Project Monitoring and Control is one of the required activities in project management. This activity provides the information about whether a project is making a progress as it is planned. It is usually performed in weekly meetings or milestone meetings where the project manager checks the project's current status based on project measures such as schedule, cost and work performance. One of the popular method for project monitoring and control is EVM(Earned Value Management). The major characteristic of EVM is that it uses only one measure 'cost' for schedule and work performance so that it enables 2 independent graphs to be illustrated in one integrated graph based on cost. For applying EVM to a project, it is essential to break whole work to work packages and to assign value of cost to each work package at the initial stage of the project. Therefore EVM is well matched with the lifecycle which requires whole plan at the beginning of project. However, in XP(eXtreme Programming), whole customer requirements are difficult to define and to make a complete plan at the beginning and are more detailed in each Iteration. Therefore EVM is not comfortable method for XP. Therefore in this research we suggest 3 layer EVM which can be applied in XP, and develop a process guidelines based on CMMI(Capability Maturity Model Integration) PMC(Project Monitoring and Control) process area.

To have successful execution of a development project on large scale, it is the most important to improve communication problems between project stakeholder. In this study, we design and implement project integrated management tools that improve the problems. In order to design and implement the tools, we gathered and arranged requirements based on the ISP data from S corporation and the problems of 23 projects which was executed in recent 2 years in a communication perspective, and then we conceptually design and propose the tools. We defined major parts of the functions and the architecture related to communication among the proposed architecture model, and we proposed process and detail functions to execute major functions. This study shows the possibility through a qualitative valuation to improve validation of the architecture model and a quantitative analysis in a communication perspective.

In this paper, we describe capstone-related courses in the Computer information department of Dongyang-Mirae University and propose a capstone design model for computer engineering discipline based on operating experiences during the last year. Class schedules and contents, etc are presented from the case studies of two courses on system analysis and design and graduation work(capstone design) opened in 2015. Towards the successful operation of capstone design targeted to training practical and talented professionals with creative problem-solving skills, we propose six execution steps along with principal activities and outputs: Course plan, Project plan, Development, Reporting, Evaluation of students and coursework, and Course feedback. The capstone design model of this study is characterized by presenting the necessity and importance of pre and post steps such as 'Course Plan' and 'Course reflux' from a macroscopic view and by applying software engineering techniques such as prototyping, configuration managements, etc to it.

The purpose of the present study was to identify how and how much teachers utilize ICT in their instruction and to analyze teachers' perception about the environmental factors to promote ICT implementation after their participation in a teacher training for Project-Based Learning (PBL) with ICT. The results showed that there was a significant change in the application of PBL into classroom and the class preparation before and after the training. Lack of time to prepare the instruction using ICT was identified as the most important reason not to utilize ICT in their classroom. While teachers perceived time and rewards among the environmental factors were lack, dissatisfaction with status quo, incentives, knowledge and skill, participation and leadership were perceived as being present in their school.

Recently, National Archives of Korea has planned to develop the Standard Archive Management System, to make it economical and efficient in accordance with the local archives establishments by Seoul Metropolitan City. Also, the institution signed the MOU with National Information Society Agency to set up a digital archive system and foster professional archival manpower. These movements are rooted on the current domestic demands for digital archive systems. Keeping pace with it, the purpose of this study is suggesting feasible ways to establish the sustainable and efficient archive systems. To this end, a status study on the existing digital archive systems at both domestic and overseas bases was carried out, with the many of open source software analysis. Based on the primary implications of this study, to implement the digital archive system, functional module deducting methods and an open source software application process on each module were designed. Financial, operational and technical considerations such as the links between modules are also considered.

Successful project planning relies on a good estimation of the manpower required to complete a project. The good estimation can be derived from Rutnam's Rayleigh Model or Phillai et al.'s Gamma Model. These models only can be applied for the projects which the need of manpower is increased exponentially and the highest of manpower is required at the end of development phase. However, in a practical project, most manpower is required during development phase and a small amount of manpower is assigned during maintenance phase. In addition, the Waterfall Model and Unified Process only can be adopted for development phase. So the current development environments cannot be adopted into the existing manpower distribution models which the highest manpower is required at the end of development phase. This paper suggests an appropriate model for development phase to solve this problem. First, the appropriate manpower distribution for development phase of the Waterfall model was derived from Putnam's manpower distribution and then manpower distribution of development phase was derived for Unified Process. After comparing the required manpower of two Processes, total manpower distribution is similar each other even though the required manpower and task is different for each point of development phase. From this result, a unified model is derived and it can be applied for both development processes.

In the construction industry, projects are becoming increasingly large and complex, involving multiple subcontractors. Traditional centralized coordination techniques used by the general contractors become less effective as subcontractors perform most wok and provide their own resources. When subcontractors cannot provide enough resources, they hinder their own performance as well as that of other subconractors and ultimately the entire project Thus, construction projects need a new distributed coordination approach wherein all of the concerned subcontractors can reschedule a project dynamically. To enable the distributed coordination framework of project schedule changes, the author developed an agent-based compensatory negotiation methodology, which allows intelligent software agents to simulate negotiations on behalf of their human subcontractors. In addition to this theoretical work, 1 designed and implemented a prototype to demonstrate the effectiveness of the framework. Thus, this research formalizes the necessary steps that would help construction project participants to increase the efficiency of their resource use, which in turn will enhance successful completions of whole projects.

As the scale of construction work is enlarged, complicated and diversified, construction information from the large number of construction sites is happened and reported to the head office. To control much information generated in construction sites simultaneously, the necessity of supporting system which can extract necessary information is increased. However, compare with large companies, medium-sized companies's organization of head office and management system is weak, so it's difficult to manage multi-projects. Among these site managements, resource management is an important management area. But, resource planning is based on experience and judgement and have not associated with schedule information. So when schedule if changed, the plan must be amended manually. This study investigates material-planning model for multi-project management which is connected with daily report system and scheduling software.

Many companies and governments perform information technology (IT) projections repeatedly for higher competitiveness and efficiency. Moreover, as the sizes of IT projects increase, the manpower and cost estimation of the projects are getting more important. In this research, we present a size estimation method of information system development projects on the basis of the function point method at the stage of information strategy planning(ISP), and illustrate the size calculation of an example IT project. According to the method, we first identify the types of projects, the scope and boundaries of size estimation, then count data and transaction functions from the artifacts of the ISP project. The unadjusted function points are adjusted to function point by the table of the Early Function Point. The way of calculating the sizes of IT projects will support successful IT projects by estimating reasonable manpower and cost for the projects.
