ESA's Concurrent Design Facility (CDF) at ESTEC is a state-of-the-art facility equipped with a network of computers, multi-media devices and software tools, which allows a team of multi-disciplinary experts to apply the concurrent engineering method to space mission design. It facilitates a fast and effective interaction of all disciplines involved, ensuring consistent, high-quality results. Some of the CDF methodologies and techniques are now the basis for the new company J-CDS in their development of a general tool for non-space industries carrying out research and development activities for complex systems. Here Hugo Brunsveld van Hulten, ESI entrepreneur and inventor behind another ESI start-up company, is seen working with ESA experts at the CDF in December 2003, on his technique to fight breast cancer.
