Improving the engineering design process by simulating iteration impact with ASM2.0

Engineering design processes that are dependent on Computer-Aided Engineering (CAE) tools commonly involve complex patterns of tasks, including concurrency and intertwined iterations. There are often inefficiencies and improvement opportunities in such processes, but it can be difficult to identify and evaluate them—partly because of the complex iteration patterns, and partly because process knowledge is usually tacit and often distributed among process participants so that it is difficult to appreciate the causes and effects of iteration in an integrated way. The Applied Signposting Model (ASM) was developed to address these issues during more than a decade of research and case studies in the aerospace sector. This article describes an evolved version of the ASM, called ASM2.0, alongside a detailed case to demonstrate its application to improve CAE-driven, iteration-intensive engineering design processes. A review of applications is also provided. A differentiating feature of ASM2.0 is that it integrates visually-familiar flowchart mapping with quantitative analysis of process performance, to enable the modelling of complex iteration patterns that are typical of engineering design practice.
