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 %K lean product development %K one-of-a-kind production %K set-based concurrent engineering %K smart industry %K Toyota product development system %U https://hrcak.srce.hr/index.php?show=clanak&id_clanak_jezik=340547
