Design processes can be understood as a continuous cycle of actions driven by the perception and reduction of uncertainty. This modelling research insight is drawn from a 2017 study published in Academic Publication. Using Conceptual modelling and literature synthesis., researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers should actively identify and address sources of uncertainty throughout their design process, using information gathering, knowledge sharing, and iterative representation as key strategies.

Design processes can be understood as a continuous cycle of actions driven by the perception and reduction of uncertainty.
Academic Publication · 2017
Key Findings
- 01Design activity can be decomposed into three core actions: information action, knowledge-sharing action, and representation action.
- 02The perception of uncertainty is the primary driver that links these core actions.
- 03The UDA model provides a unified perspective on previously disparate descriptions of design activity.
Application
Design takeaway
Designers should actively identify and address sources of uncertainty throughout their design process, using information gathering, knowledge sharing, and iterative representation as key strategies.
How to apply
When facing a complex design problem, explicitly map out the areas of uncertainty, plan actions to gather relevant information, facilitate knowledge sharing among stakeholders, and develop representations that clarify understanding.
Project actions
- 01When documenting your design process, clearly identify moments of uncertainty and the actions you took to address them.
- 02Consider how your chosen design methods help or hinder the reduction of uncertainty.

Variables
Strengths & Limitations
Strengths
- +Provides a unifying framework for diverse design activities.
- +Connects cognitive aspects (uncertainty perception) with observable actions.
Limitations
It can be challenging to objectively measure 'uncertainty perception' in a practical design project.
Reliability & validity
The model's validity relies on its ability to consistently explain observed design behaviours across different contexts. Reliability would be assessed by whether different researchers applying the model arrive at similar interpretations of a design process.
Think critically
How might different types of design projects (e.g., highly innovative vs. incremental improvement) place varying emphasis on each of the three core actions within the UDA model?
Design Principles
"Design is an iterative process of uncertainty reduction through information, knowledge, and representation actions."
Understanding design as an uncertainty-driven process provides a framework for analyzing and improving design workflows. It highlights the importance of managing information, knowledge, and representations to navigate the inherent ambiguity in design challenges.
What This Means for Your Design
Designers act because they don't know everything. They take steps to get more information, talk to others, and make drawings or models to figure things out and reduce what they're unsure about.
How to use in your project
- 1.Use the UDA model to structure your analysis of your design process, explaining how your actions were driven by uncertainty.
- 2.Refer to the UDA model when discussing the rationale behind your research and development phases.

Paragraph starter
The design process was approached through the lens of the Uncertainty Driven Action (UDA) model, recognizing that design activity is fundamentally driven by the need to reduce uncertainty. Key actions such as information gathering, knowledge sharing, and the creation of representations were undertaken to systematically address identified areas of ambiguity and inform subsequent design decisions.
