Perfectionism is a personality trait associated with a desire for flawlessness, high-standard expectations and criticism of the self and others. As engineering design seeks to address more wicked problems that move beyond technical considerations, it is possible that engineers with perfectionism may struggle to engage flexibly with complexity and more creativity-focused solutions. The present study seeks to understand perfectionism prevalence in an undergraduate cohort of civil engineers and the impact of this trait on complex design decisions and engagements that include social as well as technical considerations. 184 civil engineering students were involved in this study. We found that 74.5% of the engineers classify as perfectionists, with 68.5% of these perfectionists being maladaptive. Further, we examined how perfectionism associated with Communal Designs, a design approach that aims to meet physical community needs as well as more metaphysical, empathy-informed criteria. We found that although perfectionists were more likely to have higher scores of prosocialness and empathy, non-perfectionists were more likely to produce Communal Designs. This suggested an apparent intention-behaviour mismatch. Engineering students may have intended to but then failed to produce Communal Designs; this could also be explained via our finding that perfectionists tend to have higher social desirability scores. The results indicate that complex decision-making in engineering design cannot be separated from the mindsets and personalities of engineers. Strategies to mitigate the negative impact of perfectionism are discussed, including both supported exposure to open-ended, contextualised design, and the use of critical reflection. A regression model predictive of Communal Design production was also developed and discussed using engineering undergraduates’ personality characteristics’ scores as predictors.

The success of a product in the market is largely defined by the quality of design decisions made during the early stages of development. The product design requires designers to balance multiple objectives such as functionality, cost, and user satisfaction, while addressing the challenges posed by increasing product variants and customization demands. To tackle these challenges, one approach is to structure a comprehensive model that incorporates design for assembly (DFA) guidelines during the formulation of product architecture in the conceptual phase of development. While numerous strategies have been proposed in the literature, information is often scattered, making it difficult for readers to gain a comprehensive understanding of the topic. This paper systematically reviews the role and impact of DFA in product development, consolidating and presenting the information coherently. The review provides an overview of the methods developed, along with their potential benefits and limitations. A common framework is identified that defines the structure of the models, helping designers integrate assembly consideration into their design processes, thus reducing assembly time, cost, and complexity. The framework describes the operational setting, including the domain and context in which models operate, and offers a classification of possible methods and desired outputs. Additionally, the review identifies the industry in which case studies have been most frequently presented, and the software used to facilitate the process. By connecting with such a framework, future models can be created following a structured approach, and existing models can be classified and upgraded accordingly.
