In the quality management context, simulation refers to the use of models and computer programs to replicate a process or system in order to predict outcomes, assess risks, and improve the understanding of potential quality issues before they occur in real-world operations. Simulation allows organizations to test changes, optimize processes, and evaluate the effectiveness of quality management strategies without the cost and risk associated with physical trials.

General Description

Simulation in quality management involves creating detailed models of processes, from manufacturing lines to service delivery workflows, to analyze how changes in one part of the system might affect the overall quality of outputs. This can include everything from material flow and labor allocation to the impact of machine settings on product quality.

Areas of Application

  • Process Optimization: Identifying bottlenecks and inefficiencies in production or service processes.
  • Risk Management: Assessing the potential impact of new processes or changes to existing ones on product quality.
  • Resource Allocation: Planning the optimal allocation of resources to maintain or improve quality levels.
  • Training: Providing a virtual environment for training personnel on complex processes without the risk of quality issues in actual production.

Well-Known Examples

  • Using simulation to predict the effects of changes in manufacturing parameters on the quality of automotive parts.
  • Simulating customer service processes in a call center to identify strategies for reducing waiting times and improving customer satisfaction.


While simulation is a powerful tool, it relies heavily on the accuracy of the models and assumptions used. Inaccurate or oversimplified models can lead to misleading results, potentially guiding managers towards ineffective or counterproductive decisions.


To mitigate these risks, it is essential to:

  • Use detailed and accurate data to build models.
  • Regularly update and validate models against real-world outcomes.
  • Combine simulation results with expert knowledge and other quality management tools.


Simulation is a valuable technique in quality management, offering a risk-free way to analyze and improve processes, manage risks, and optimize resource allocation. By allowing organizations to test scenarios and predict outcomes, simulation supports informed decision-making and continuous improvement in quality management efforts.
