CD enabling IT, design technology and tools New design technologies are used to foster efficient cross-disciplinary analysis, experim entation, and representation of new product designs, e.g.: • three-dim ensional ( 3 -D) com puter-aided design ( CAD) • sim ulation • digital m ock-up • rapid prototyping ( RP) • stereo projection. Their 3 -D rendering: - allow s the expert to interpret design features, - im proving com m unication, - reducing m isunderstandings, - helping to find solutions For CE to be successful, inform ation and interpretation “asym m etries” am ong the experts m ust be avoided, w henever possible ESA UNCLASSIFIED - For Official Use

CD is on-line, real time, highly interactive design Methodology: Approach: - iterative presentations - Multidisciplinary - debate - Holistic - consensus - Systematic - system awareness - Centralized - … - focus on Customer ESA UNCLASSIFIED - For Official Use expectations SESSION - …

Process Elements – Conducted in sessions plenary m eeting w here representatives of all space – engineering dom ains participate from early phases ( requirem ent analysis) to end of design ( costing) – 6 to 1 0 session / study, 4 hour / session, bi-w eekly frequency – team leader ( or facilitator) co-ordination – custom er participation Model driven – – On-line design – Highly co-operative & interactive – I terations Design options com parison and trade-offs – ESA UNCLASSIFIED - For Official Use

CDF dynamics – Centralised architecture Process:  Specialist “k” performs Discipline i an estimate and shares data in CR  Data is available to other specialists  Each specialist can use this data to perform calculations and share the results … Discipline j x. System makes budgets Cost y. Overall process iterates … z. Final design done, all information available in Central Repository (CR) CR System “Data” Discipline k ESA UNCLASSIFIED - For Official Use
