There are many defects that cause the schedule and qualify problems during software development. This paper designs the opportunity tree framer work that removes and manages the schedule and quality problems as well. For the similar projects, we can estimate defects and prepare to solve them by using domain expert knowledge and the opportunity tree framework which can greatly improve the software process. This research provides solution of schedule defect problem and detection of defect and its causes that happen on software development.

This paper identifies defects to produce a reliable software and analyzes the relationship between defects. Also, this paper is intended to develop the relationship between defects and their causes to introduce. For the doing, first, to meet to customer satisfaction and make flexibility and productivity and second. to maximize market extension and financial outcome by controlling of quality and delivery.

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.

There are many defects that cause the process improvement of lifecycle problems during software development. This paper propose the management method of risk items that removes and manages the lifecycle problems as well. For the similar projects, we can estimate defects and prepare to solve them by using domain expert knowledge and the state analysis of defect items, which can greatly improve the software process. This research provides solution of management of risk items problem and detection of defect transition and its prevention and causes that happen on software development. Also, In this paper propose to making quantity of degree and transition phase.

최근 많은 기업들은 효과적인 소프트웨어 프로세스 개선을 위해 SPICE와 CMMI 프로세스 심사 표준을 도입하려는 노력을 하고 있다. 이러한 표준을 통해 효과적인 개선하기 위해서는 개선점과 위험을 식별하고 이들 이슈들을 소프트웨어 개발환경(software development environment)에 적용시켜서 조직의 비젼(organization vision)에 대응한 작업성능(work performance)를 높여야한다. 지속적인 개선을 필요로 하는 조직은 현재의 작업성능을 측정하고 이를 개선하기 위한 개선점을 찾아내는 능력과 경험을 축적하여 체계적으로 관리하는 것이 중요하다. 하지만 기존의 SPI 모델들은 무엇을 수행해야 하는지에 대한 지침은 제공하고 있지만, 정량적인 작업성능 측정 및 특정 환경의 소프트웨어 개발 조직의 SPI를 위해 필요한 구체적인 지침을 제시하고 있지는 않다. 따라서, 본 논문에서는 이러한 조직의 작업성능 측정 및 조직의 개선경험을 축적하여 프로세스를 개선전략에 반영하여 조직의 비젼에 최적한 전략을 제공해주는 OTEM(Opportunity Tree Enterprise Model)을 제안한다.
