Integrating Lean Six Sigma and System Dynamics Enhances Project Performance Measurement
Combining Lean Six Sigma principles with System Dynamics modeling provides a robust framework for data-driven decision-making in construction projects, improving the accuracy of performance evaluation.
Journal of Civil Engineering and Management · 2026
Key Findings
- 01Eliminating waste causes had a minimal impact on project performance in early project stages, with the impact increasing as the project progressed.
- 02Improvements in project quality were minimal for 'increases of errors and omissions in design documents' but maximal for 'increasing morale and attitude affect the quality of the project'.
Application
Design takeaway
Implement integrated LSS and SD models to dynamically assess project performance, recognizing that the impact of interventions evolves throughout the project lifecycle and that human elements are critical for quality.
How to apply
Develop and utilize system dynamics models that incorporate LSS metrics to simulate the impact of different waste reduction and quality improvement strategies at various project stages.
Project actions
- 01When analyzing project performance, consider how the impact of your interventions changes as the project progresses.
- 02Investigate the relationship between team morale and project quality in your own design projects.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Integration of multiple advanced methodologies (LSS, SD, EVM).
- +Use of expert opinion (DEMATEL) to identify key causal relationships.
- +Development of dynamic models for performance assessment.
Limitations
The complexity of system dynamics modeling can be a barrier. Expert opinions, while valuable, can introduce bias.
Reliability & validity
Reliability could be enhanced through repeated simulations with varied parameters. Validity is supported by expert input (DEMATEL) and the established frameworks of LSS and EVM, but the specific SD model's predictive validity would require real-world project data for thorough testing.
Think critically
To what extent can the 'waste causes' and 'quality causes' identified in this construction context be generalized to other design or manufacturing domains, and how might their interdependencies differ?
Design Principles
"Dynamic performance assessment: Project performance metrics should account for the evolving impact of interventions and interdependencies over time."
This integrated approach allows for a more nuanced understanding of project dynamics, moving beyond static metrics to capture the interdependencies between waste reduction, quality improvement, and overall project progress. It enables proactive identification of critical factors influencing performance.
What This Means for Your Design
By combining different management tools, this study shows how to better track and improve construction projects by understanding how fixing problems at different times and focusing on people affects the outcome.
How to use in your project
- 1.Use the concept of integrating multiple analytical tools (like LSS and SD) to justify your chosen research methodology.
- 2.Discuss the temporal impact of design decisions or material choices on project outcomes, similar to how waste reduction impact was analyzed over time.

Paragraph starter
This research highlights the value of integrating Lean Six Sigma principles with System Dynamics modeling for enhanced Earned Value Management in construction. The study's findings suggest that the impact of waste reduction efforts and quality improvement initiatives is not static but evolves throughout the project lifecycle, with human factors like morale playing a significant role in quality outcomes. This approach offers a more data-driven and dynamic method for project performance assessment.
