Many engineering executives are now confident that MBD can deliver significant benefits. Yet, a number of them hesitate because of the uncertainty in their supplier’s readiness to use MBD deliverables. These findings reveal the readiness of suppliers, whether they be internal organizations or external companies, in the adoption of MBD across quoting, machining, tooling design, and inspection functions. Findings from this study will give engineering executives insight into the current adoption of model-based practices and processes. But more importantly, it will allow them to understand if suppliers are currently capable, even if they are not currently employing those capabilities.
