신개발 제품의 품질보증 시스템에 관한 연구 = Quality Assurance System on the Newly Developing Products

다국어 초록 (Multilingual Abstract)

In the 1990s the Uruguay Round structure will be fixed ; the market development, which also has been accelerated in the world economic environment and in the local economy, will be diffused into EC integration ; and the world economy will take a new turn through the age of multipolarized world like rising of the Japanese economy and increasing importance of developing countries.
Nowadays, in the international technology market, each country turns down transference of her core technology by means of technology protection barrier. The so called age of technology as a weapon has entered, and the product life cycle(PLC) becomes shorter as technology competition, that is the source of competitive power of a company, accelerates. One of the causes is that Consumers needs are various and rapidly changing.
To successfully cope with the environmental challenges and to improve international competitive power, it is necessary to upgrade quality competitive power that can lead the development of high quality products and value added products according to technological innovation.
Quality management needs new concepts and practical rules which are different from the past. Until now, we have executed that ex-post quality control which emphasizes prevention of recurrence of defects.
This activity has done good to decrease the ratio of inferior goods and to gain efficiency of production process. But it does not satisfy the customers needs.
During that time, we have had some problems in producing floors. We have taken a serious view of the statistical methods of efficiency and effectiveness of the whole company. But customers needs have not been understood sufficiently, so it is not reflected in the developmental step, and managerial skill of aggregating functions is immature.
Prior quality control takes effectiveness in that the quality management activities are harmonious from developmental step to sale/service step. Now, quality management activities have to switch from ex-post quality control to prior quality control to satisfy various demands of the market. We should approach quality assurance. In developing a new product, quality assurance should be performed to provide adequate confidence that a product or service will satisfy the given requiremental qualities of the customers.
The empirical test of quality management activities to the newly developing product revealed a lot of problem. Most manufacturing companies did not self-design and did not have design review activities. Specially the ratio of self-designing(below 30%) to mimic-designing companies occupied 57.4% of respondents. And only 3.0% of the answers performed DRCL(Design Review CheckList) and DRC(Design Review Committee) management activities. Most employees did not understand quality function deployment system (Quality Evolution), and process management for developmental step of a new product was not executed or was performed with only gantt chart in most companies. The members of development/design department had comparatively low career and short length of the service. Moreover, the proportion of development/design members to the wholey employee was very low, and the department for developing new products did not exist separately in 37.3% companies of the answers. The facts mentioned above have resulted from the lack of investment and managerial technology for quality assurance during the new produce development.
To solve these problems and to improve the level of quality management, we need to practice quality assurance from developmental step. Quality assurance on the newly developing product should start from collecting correct quality information by means of quality function deployment system. And quality function deployment system is to define the "voice of the customer" in operational terms and in the training of the designers for "practical experience" - experience in the production shop and field service work- in order to improve producibility and reliability. In short, we should establish a quality of design which will satisfy and which will transfer the importance of design to the production process in quality function deployment system. For this purpose, this paper presents a simple function deployment system instead of a huge system.
The following are items required for improvement of the level of quality assurance activities :
1. Introduction of quality function deployment system
2. Reinforcement of customer-oriented design review system
3. Preparation of more detailed quality assurance flow chart and activity list : quality checklist is especially useful for the following.
a. To quantify and to connect requiremental quality and essential technology
b. To shorten developing schedule and to reduce activities in designing step
c. To meet need of the customers
d. Accumulate and to organize essential technologies
Quality assurance activities in developmental step are needed to acquire competitive power. Especially quality function deployment system and design review which will be effective in short terms should be introduced and made practical application of.
