Designing Design Processes in Product Lifecycle Management: Research Issues and Strategies

Product Lifecycle Management (PLM) promises to further a holistic consideration of product design, emphasizing integration, interoperability, and sustainability throughout a product’s lifecycle. Thus far, efforts have focused on addressing lifecycle concerns from a product-centric perspective by exploiting the reusability and scalability of existing products through product platform and product family design. Not much attention has been paid to leveraging the design process and its design in addressing lifecycle considerations, however. In striving for sustainability, it is the design process that should be considered to constitute an engineering enterprise’s primary resource commitment. In this paper, an overview of the challenges inherent in designing design processes is provided. These challenges are subsequently illustrated with regard to several design scenarios of varying complexity, using an example involving the design of Linear Cellular Alloys. A distinction is made between product related requirements/goals and design process related requirements/goals. Requirements, research issues, and strategies for addressing the diverse needs of modeling design processes from a decision-centric perspective are established. Finally, key elements for enabling the integrated design of products and their underlying design processes in a systematic fashion are provided, motivating the extension of PLM to include the lifecycle considerations of design processes, thereby moving towards Design Process Lifecycle Management (DPLM).
