D 자동차가 새 자동차를 개발하는 과정에 스타일 디자인은 이태리에서, 샤시 설계는 영국에서, 파워트레인 설계는 독일에서 수행하였다고 한다. 글로벌 경영이나 현지 법인이라는 단어들도 이제는 낯설지 않은 용어들로 자리잡아 가고 있는 중이며, 앞으로는 리비아, 우즈베키스탄, 베네주엘라 등 전세계에 흩어져 있는 기업의 현장을 어떻게 운영해 나갈 것인지를 연구해야 할 것이다. 무역장벽을 극복하기 위해 설립하고 있는 현지의 공장들을 서울에 앉아서 가동시키는 방법 중에, 인터넷을 이용하는 방안이 CALS(Commerce At Light Speed 또는 Computer Aided Logistic Support)라고 할 수 있다. 이는 인터넷을 통해 기업의 무역거래 서류, 카탈로그, 설계도면, 사용자 지침서 등을 전자문서로 주고 받을 수 있게 하겠다는 생각에서 추진되고 있는 프로젝트이다.

많은 기관들이 안전관리에 적극적으로 나서지 못하는 이유 중 하나가 바로 비용 문제 때문이다. 안전관리 활동이 많아질수록 들어가는 비용은 증가하게 되고, 일부 기관은 비용을 이유로 안전관리활동을 축소하기도 하는 것이 현실이다. 이러한 문제가 해소되기 위해서는 무엇보다 경영진의 의식개선과 안전활동에 대한 안전관리자의 적극적인 노력이 절실하다. 한국기계연구원 부설 재료연구소는 이 점에서 하나의 모범사례와도 같다. 경영진의 뒷받침 속에 안전예산확보, 다양한 안전 프로젝트를 시행하고 있기 때문이다. 재료연구소를 찾아가 안전환경 조성을 위해 어떠한 활동을 펼치고 있는지 이야기를 들어봤다.

A large-scale IS development project takes a long time, thus its project manager needs to be more careful on risk management. In particular, appropriate cutover decision making is critical in large-scale IS development projects because the opening of the large-scale IS significantly impacts the organization. Regardless of its importance, cutover decision making in conventional IS development projects has been done in a quite simple way. Conventional cutover decisions have been made by considering just whether the new IS operates or not from the system, application, and data implementation perspectives. However, this approach may lead to unsatisfactory performance or system failure in complex large-scale IS development. Under this background, we propose a new framework for cutover decision making on large-scale IS projects. To validate the applicability, we applied the framework to a core banking system development case. The case study shows that our framework is effective in proper cutover decision making.

As the domestic consulting industry matured, consultants were required to have insight into customer's business and consulting business. Gaining these insights requires deep understanding of the business domains and high degree of competencies. This study empirically analyzed the data collected through the survey in order to apply the ICMCI competence model to domestic consultants. As a result of the study, it was found that business competency and technical competency had a positive effect on project performance, but values & behavior competency were not statistically significant. On the other hand, it was found that only technical competency, values & behavior competency had a positive effect on social-relational competency. Through this study, it was confirmed that a deep understanding and perception of the consulting business is necessary to grow into a professional consultant, but there is a limit to generalizing the research results because the characteristics of the population cannot be sufficiently reflected with a small sample.

Today, IT organizations perform projects with vision related to marketing and financial profit. The objective of realizing the vision is to improve the project performing ability in terms of QCD. Organizations have made a lot of efforts to achieve this objective through process improvement. Large companies such as IBM, Ford, and GE have made over $80\%$ of success through business process re-engineering using information technology instead of business improvement effect by computers. It is important to collect, analyze and manage the data on performed projects to achieve the objective, but quantitative measurement is difficult as software is invisible and the effect and efficiency caused by process change are not visibly identified. Therefore, it is not easy to extract the strategy of improvement. This paper measures and analyzes the project performance, focusing on organizations' external effectiveness and internal efficiency (Qualify, Delivery, Cycle time, and Waste). Based on the measured project performance scores, an OT (Opportunity Tree) model was designed for optimizing the project performance. The process of design is as follows. First, meta data are derived from projects and analyzed by quantitative GQM(Goal-Question-Metric) questionnaire. Then, the project performance model is designed with the data obtained from the quantitative GQM questionnaire and organization's performance score for each area is calculated. The value is revised by integrating the measured scores by area vision weights from all stakeholders (CEO, middle-class managers, developer, investor, and custom). Through this, routes for improvement are presented and an optimized improvement method is suggested. Existing methods to improve software process have been highly effective in division of processes' but somewhat unsatisfactory in structural function to develop and systemically manage strategies by applying the processes to Projects. The proposed OT model provides a solution to this problem. The OT model is useful to provide an optimal improvement method in line with organization's goals and can reduce risks which may occur in the course of improving process if it is applied with proposed methods. In addition, satisfaction about the improvement strategy can be improved by obtaining input about vision weight from all stakeholders through the qualitative questionnaire and by reflecting it to the calculation. The OT is also useful to optimize the expansion of market and financial performance by controlling the ability of Quality, Delivery, Cycle time, and Waste.

Planning for the expansion of production capacity is of vital importance in many applications within the private and public sectors. This paper considers a sequencing expansion problem in which capacity can be added only at discrete points in time. Given the demand forecast of each period, capacity and cost of each expansion project, we are to determine the sequence of expansion necessary to provide sufficient capacity to meet the demand in all periods at minimum cost. This problem is formulated as a pure integer programming and solved by branch and bound method using Lagrangian relaxation. At first, simple sequencing expansion problem is presented, and in the latter part, extension to include precedence between projects is suggested.

Earned Value Management System(EVMS) is a highly efficient tool in the project management, but it cannot easily determine the Actual Cost due to the indistinct criteria and extensive data. This study introduces a EVMS for project management and its actual case based on EVMS and ERP system which some additional modules are installed for performance measurement. It is expected that this new method enables a company to improve transparency by specifying expense items in detail and to switch quarterly settlement to monthly by reducing the time of calculation.

We consider a project time-cost tradeoff problem with two milestones, where one of the jobs has an uncertain processing time. Unless each milestone is completed on time, some penalty cost may be imposed. However, the penalty costs can be avoided by compressing the processing times of some jobs, which requires additional resources or costs. The objective is to minimize the expected total costs subject to the constraint on the expected project completion time. We show that the problem can be solved in polynomial time if the precedence graph of a project is a chain.

Evaluating a project is one of the key activities in managing projects, and thus it should be implemented as a part of the entire project management system. However, currently deployed systems suffer from deficiencies such as the lack of supporting distributed environment and integrity problems. Web service technology, which enables applications to work inter-operatively under a distributed computing environment, is said to solve such problems. In this paper, the web service technology is applied to evaluation management systems. The process of evaluation is designed based on the web service, data is modeled and a pilot system is implemented to test the feasibility of the technology to the domain of project evaluation.

Recently, industrial environments have been drastically changed. Customers require cheaper, better, stronger products more than ever. Thus companies have to satisfy the requirements of customers to be survived in this kind of industrial environments. To cope with these requirements from customers, engineers in industries must accept new paradigm and use some special tools for developing new product. This study has applied a Concurrent Engineering which would be good for shortening of product development period in developing of Full Logic Deck mechanism using in car audio. In this paper, a real case of systematic approach and successful story of Concurrent Engineering application in developing Full Logic Deck mechanism is illustrated.
