ABSTRACT
The Set-Based Concurrent Engineering (SBCE) is the process at the core of Lean in Engineering. This approach consists of establishing as soon as possible the accessible design space by identifying trade-offs and interactions between variables, then developing the knowledge required to gradually narrow down this space towards the best solution. Set-Based Design just acknowledges that it is precisely upfront that the designers’ freedom is the greatest and the learning cost the lowest. The real paradox is in the Point-Based Design. SBCE is often seen only as a way to process several options simultaneously. While increasing the number of options increases the probability of having a solution that works, this probability is higher if the options help to delineate the region of the design space where to find the best one.
