Small companies are the backbone of any nations industry and they are often sub contractors to major corporations, which set higher and higher demands on them. In order to survive they will inevitably be obliged to comply with the requirements [Onori et al., 2000]. In order to do so, one step is to increase their technology level. Therefore, this paper focuses on modular FAA in order to facilitate the implementation of FAA-systems into small companies. How well companies succeed in the implementation of a new technology in manufacturing depends largely on how well they understand the dependency between products and processes. Is it the right technology for the companies manufacturing system? What has to be done to the products in order to use this technology? A paradox is that new technology in manufacturing can often be justified only when a new product launch is planned. This is probably true also in the case of Flexible Automatic Assembly Systems (FAA) where the possibilities to introduce a well functioning system to use with existing products are very limited.
