All stages in a product’s life cycle, whether during product development, mass production or even when the product has been delivered to the customer, might require some engineering changes. Generally, most engineering changes takes place during mass production rather than during the product development stage. In fact, because of the rapidly growing new technology and the uncertainty of customer demand in the market, the research and development team is required to have the ability to react quickly in order to achieve higher quality at lower cost. The TFT-LCD industry is aiming for product diversity and time to market; therefore, the design change during the new product development stage is even more important. New product developments are based on the strategic vision of the company, target product and market areas. The information established in the product development system is applied to develop products. If research and development, production, and marketing functions can keep close connection, the reduction of product development time can then be achieved through a proper design change management, and the time to market of a new product can be accelerated, thus bringing profit to the company. Therefore, the design change of a product at the development stage requires a complete process, operational procedures, and electronic systems to implement an efficient design change in a new product.
This study proposes a process for the design change of the TFT-LCD new product development. This process has the advantage of linking the design change process with tape out processes, reducing paper work for the research and development team, and decreasing the complexity of implementing design changes. In addition, all the design changes records can be preserved systematically and be shared within the company. This study is based on a leading manufacturer of TFT-LCD in Taiwan. Through the great efforts from the project team members, the design change process, standard operational process documentation, and the establishment of e-management system can be accomplished and these related trainings are also provided to the users and suppliers’ systems for practical operation.
