The purpose of this thesis is to suggest effective joint-development process and its managerial guideline in the semiconductor equipment industry. Through the review of literature and in-depth cases analyses, this study suggests four stages of joint-development are process, such as: i) partner selection, ii) partnership structuring, iii) development and iv) evaluation. Also 16 success factors of joint-development are identified. Among 6 types of joint-development according to buyer-supplier relationship, 3 types which appeared in Korean semiconductor business are investigated such as : i) domestic device manufacturer(buyer) and domestic equipment manufacturer(supplier), ii) domestic device manufacturer and foreign equipment manufacturer, iii) domestic device manufacturer and joint venture equipment manufacturer.
In-depth case studies are performed to verify the joint-development process model and success factors. Interviews with managers of the joint-development are carried out.
The analysis of the cases shows that all the cases follow the stages of joint-development process in the model. Also key success factors are identified such as: the match of both parts' needs narrow focused target, commitment, communications, manpower exchange, in-time development, productivity of the equipment and user's support.
The influencing factors for each stage are also derived as follows:
In the partner selection stage, the important factors are match of both parts' needs, clear role definition, and maintaining top managements' support.
In the partnership structuring stage, contribution from each part should be defined clearly. If the partner relationship is competitive, formal contracts are preferred to commitment based on mutual trust. Even if the partnership is complementary each other rather than competitive and mutual trust is lacking, it still needs formal contracts to facilitate the development.
In the development stage, the communication is the important factor for the success of the development. Computer and network systems are very useful tools in promoting communication.
In the evaluation stage, users' active participation and supports are critical. Post joint-development activities are also very important. Even though the equipments have developed, the performance of the equipment should be audited, evaluated and revised to adapt to new work environment. To maintain equipment productive, user's roles such as evaluation and feedback are required.
