Abstract The value stream in product development (PD) is information flow. Therefore, the value of information needs to be increased, while waste of information needs to be eliminated in lean product development (LPD). Although the concepts value and waste in PD have both been the object of research activities, the dependency between them has been only addressed by a few authors. Therefore, this paper aims to examine the understanding of value and waste of information and their dependency in industrial practice. A web-based survey has been conducted in industry, which resulted in insight in industrial practice regarding definitions of value and waste, approaches to manage and assess value and waste, as well as companies’ reasons for and challenges in the implementation of LPD. Finally, the need for further research from an industrial perspective was revealed. Keywords Lean product development

1 Introduction Lean in product development (LPD) has been deployed in order to improve processes and their output in industrial practice [1]. LPD is oriented towards the fulfillment of customer requirements by enhancing value and minimizing waste. The question of how LPD—with its principles, guidelines and techniques—can be better adopted in product development (PD) is attracting increased attention. Value in product development (VPD) can be defined as ‘a capability provided to a customer at the right time at an appropriate price, as defined in each case by the customer’ [2]. A wide range of tools is associated with Lean Thinking. These tools, such as standardization of processes, effective communication, and a continuous flow of information, aim to increase the value (e.g. [3]). Womack [2] defines waste as ‘‘any human activity which absorbs resources but creates no value’’. Engineering design can be regarded as an information creation and transformation process that aims to deliver a ‘recipe’ that satisfies the customer requirements [3]. Thus, in PD the value stream is represented by the flow of information produced within the product development process (PDP) [4]. Therefore, it is crucial to regard waste in PD in terms of information. Waste of information is therefore considered to occur when information is created, transformed and/or transferred without adding any value regarding the fulfillment of customer requirements [5].
