TL;DR

This paper presents a cognitive-ergonomics framework for understanding individual and collective design processes, emphasizing how ill-defined problems and varying solution representations affect design outcomes. It identifies key cognitive activities—control, executive functions, co-design, and argumentation—demonstrating that collective design enhances problem-solving through distributed cognition and synchronized reasoning.

ABSTRACT

This text presents the cognitive-ergonomics approach to design, in both its individual and collective form. It focuses on collective design with respect to individual design. The theoretical framework adopted is that of information processing, specified for design problems. The cognitive characteristics of design problems are presented: the effects of their ill-defined character and of the different types of representation implemented in solving these problems, amongst others the more or less "satisficing" character of the different possible solutions. The text first describes the cognitive activities implemented in both individual and collective design: different types of control activities and of the executive activities of solution development and evaluation. Specific collective-design characteristics are then presented: co-design and distributed-design activities, temporo-operative and cognitive synchronisation, and different types of argumentation, of co-designers' intervention modes in the design process, of solution-proposals evaluation. The paper concludes by a confrontation between the two types of design, individual and collective.

Motivation & Objective

• To analyze the cognitive processes underlying individual and collective design from an ergonomics perspective.
• To investigate how the ill-defined nature of design problems influences solution representation and evaluation.
• To examine the role of cognitive synchronization and argumentation in collaborative design settings.
• To compare individual and collective design in terms of control mechanisms and solution development strategies.
• To identify how distributed cognition supports more effective and adaptive design outcomes in teams.

Proposed method

• Adopts an information-processing theory framework tailored to design problems.
• Analyzes cognitive activities such as control, planning, and evaluation in individual and collective design contexts.
• Examines co-design and distributed-design activities as forms of collaborative problem-solving.
• Investigates temporal and cognitive synchronization in team design processes.
• Classifies intervention modes and argumentation types used by co-designers during solution development.
• Uses qualitative analysis of design processes to compare individual and collective design dynamics.

Experimental results

Research questions

• RQ1 How do the cognitive characteristics of ill-defined design problems shape individual design processes?
• RQ2 In what ways do different types of solution representations (e.g., satisficing vs. optimal) influence design outcomes?
• RQ3 How does cognitive synchronization support effective collective design in distributed teams?
• RQ4 What are the distinct roles of argumentation and intervention modes in co-design processes?
• RQ5 How does collective design differ from individual design in terms of control and executive functions?

Key findings

• Individual design is constrained by cognitive load and the difficulty of representing ill-defined problems, leading to satisficing solutions.
• Collective design enables better handling of complexity through distributed cognition and shared representation.
• Temporal and cognitive synchronization are critical for effective co-design, especially in real-time collaborative environments.
• Multiple modes of intervention—such as proposal, critique, and refinement—enable dynamic solution evaluation in teams.
• Argumentation in collective design supports the evolution of solutions toward higher quality and more robust outcomes.
• The paper concludes that collective design enhances design quality by integrating diverse cognitive resources and reducing individual cognitive limitations.
