Generative design tools, while powerful for optimizing performance, primarily process quantitative data, requiring designers to translate qualitative aspects like aesthetics into measurable parameters. This modelling research insight is drawn from a 2023 study published in Proceedings of the Design Society. Using Qualitative research (interviews) with 6 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When using generative design tools, proactively define how subjective design criteria will be translated into objective, measurable inputs to guide the AI towards desired aesthetic and functional outcomes.

Key Findings
- 01Generative design tools primarily accept quantitative inputs.
- 02Qualitative design aspects (e.g., aesthetics) are indirectly considered by designers through the translation of these qualities into quantitative metrics.
- 03Designer subjectivity in inputting and interpreting data leads to varied outcomes.
- 04Differences in tool usage are observed between expert and novice computational designers.
Application
Design takeaway
When using generative design tools, proactively define how subjective design criteria will be translated into objective, measurable inputs to guide the AI towards desired aesthetic and functional outcomes.
How to apply
Before using a generative design tool, create a clear list of all desired aesthetic qualities and brainstorm how each can be represented by numerical values or constraints within the tool's input system.
Project actions
- 01When using generative design tools, clearly document how you are translating subjective design goals into objective parameters.
- 02Reflect on how your personal preferences or expertise influenced the quantitative inputs you provided to the tool.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Provides direct insights from designers actively using generative tools.
- +Highlights the practical challenges of integrating AI into creative workflows.
Limitations
The study's findings are based on a small number of interviews, so the observed behaviours might not apply to all designers or all generative design tools.
Reliability & validity
The study's validity is supported by the qualitative depth of interviews, but its reliability might be limited by the small sample size and potential for interviewer bias. Triangulation with other research methods could strengthen its reliability.
Think critically
To what extent does the reliance on quantitative inputs in generative design tools risk homogenizing design aesthetics, and what strategies can designers employ to maintain unique creative expression?
Design Principles
"Translate qualitative design intent into quantifiable metrics when employing generative design tools."
Understanding this shift is crucial for designers integrating AI-powered tools. It highlights the need for new workflows that bridge the gap between objective performance optimization and subjective design intent, ensuring that the final product aligns with both functional requirements and user experience goals.
What This Means for Your Design
Generative design software is good at optimizing things based on numbers, but it can't 'feel' what looks good. Designers have to turn 'looks good' into numbers for the software to understand, and this process can be different for everyone.
How to use in your project
- 1.Reference this study when discussing the challenges of incorporating aesthetic considerations into computationally driven design processes.
- 2.Use the findings to justify your methodology for defining and inputting design constraints for generative tools.

Paragraph starter
The integration of generative design tools into the design process necessitates a careful consideration of how qualitative design aspects are translated into quantitative inputs. As observed by Saadi and Yang (2023), these tools primarily process objective data, requiring designers to develop strategies for representing subjective criteria, such as aesthetics, in a measurable format. This shift impacts designer behaviour by emphasizing the interpretation and definition of parameters, potentially leading to varied design outcomes based on individual subjectivity and expertise.
