Design Change Complexity Increases Production Risk
The inherent complexity of design changes, arising from interactions between static design elements, their descriptions, and dynamic task actions, significantly increases the risk of production errors and inefficiencies.
Open Research Online (The Open University) · 2005
Key Findings
- 01Design change complexity stems from the interplay of static design elements (connectivities, processes, resources, requirements), their descriptions, and the actions taken on these descriptions.
- 02Complexity can manifest in various aspects of the design model, impacting the predictability and manageability of changes.
Application
Design takeaway
Implement rigorous change control procedures that account for the interconnectedness of design elements, their documentation, and the production workflow.
How to apply
When planning for design changes, map out all affected components, documentation, and production steps, and assess potential ripple effects.
Project actions
- 01When proposing a design change, clearly outline not only the modification but also the rationale and potential impacts on production.
- 02Consider using visual aids like system diagrams to illustrate the complexity of proposed changes.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Provides a structured framework for analysing design change.
- +Identifies key areas where complexity arises.
Limitations
The complexity of real-world production environments may be greater than what can be captured in a simplified model.
Reliability & validity
The conceptual nature of the model means reliability and validity would need to be established through empirical testing in diverse design and production settings.
Think critically
How can a design team proactively identify and mitigate the sources of complexity in design changes before they impact production?
Design Principles
"Manage design change by explicitly modelling and understanding the relationships between design artifacts, their representations, and the processes that act upon them."
Understanding the multifaceted nature of design change complexity is crucial for effective production planning and risk mitigation. Designers and production managers must anticipate how changes propagate through the design and manufacturing ecosystem to avoid costly rework and delays.
What This Means for Your Design
Changing a design is complicated because it's not just about changing the thing itself, but also how you describe it and how that change affects everything else in the production system.
How to use in your project

Paragraph starter
The complexity inherent in design changes, as highlighted by Earl, Eckert, and Clarkson (2005), underscores the importance of a systematic approach to managing modifications. Their model, which distinguishes between static design elements, their descriptions, and dynamic task actions, reveals how changes can propagate through interconnected systems, increasing the risk of production errors. Therefore, any proposed design alteration must be accompanied by a thorough analysis of its potential impact on all related aspects of the design and manufacturing process.
