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.
02

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.
03

Method & Evidence

AimTo identify and categorize the sources of complexity in engineering design changes and their impact on the design process.
MethodConceptual analysis and modelling
ProcedureThe researchers developed a model to represent design change, distinguishing between the static background of design elements, their descriptions, and the dynamic actions performed on these descriptions. They then analyzed sources of complexity within this framework.
ContextEngineering design and production

Variables

IVNature of design change (e.g., minor vs. major, component vs. system)
DVLevel of complexity encountered, number of production issues, time/cost overruns
CVType of product, maturity of design, existing production processes
04

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?

05

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.

06

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

  • 1.Refer to this research when discussing the challenges of implementing design changes in your project, particularly if your design involves multiple interconnected components or processes.

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.
