The design of complex systems requires detailed analysis to be moved earlier in the design process. Value Driven Design methodologies extend the Requirements Management and Systems Engineering processes to reduce time and costs needed to identify the right solution direction to be pursued in detailed design. Emerging from the findings of an EU FP7 research project, the paper describes an approach for preliminary concept selection, named EVOKE, that uses value as a basis for decision. EVOKE enables quick value analysis to be executed by component manufacturers by taking as input a set of value dimensions and drivers communicated by the system integrators, together with information about the high-level engineering characteristics of the sub-systems under consideration. The approach and its technological enablers are described in detail through the use of a case study related to the design of new intermediate compressor case for turbofan engines.
