Communication between cost estimators with commercial (CE-C) and engineering (CE-E) backgrounds is essential for good internal practice. This paper presents a Function-Based Cost Estimating (FUCE) framework to link the commercial and engineering communities through a structured approach at the conceptual design stage. The objective of FUCE is to translate the un-quantified terminology and the requests associated with the product specifications used by CE-C into a medium that CE-E can process using their resources, and creates estimates that are based on a standardised approach. The FUCE approach starts with functional decomposition, and then identifies product parameters that are related to a top level function and finally associate product costs to the function using past knowledge and data. FUCE is developed using a detailed case study on an automotive exhaust system. The methodology is then validated on two case studies from automotive and aerospace industries.
