Abstract

The study conducts research on lean product development (PD) methodology and presents a case study of its practical application into a specific one-of-a-kind development of large power transformers. The demonstrated framework is the result of a 5-year intensive research that led to an extensive transformation of a traditional PD environment into a highly efficient process according to lean principles. Paper explains how lean PD integrates with robust, concurrent and smart design strategies in highly individualized PD business. A generalized framework of PD and design process renovation is presented, comprising three main fields of interest: Process & Tools, People, and Knowledge. A direct consequence of implied renovation are significant savings. Case-study company cut down engineering changes by 32 % in three year test period and experienced performance improvement between 25 % and 83 % across designated process indicators.
