Understand the Difference Between Verification and Validation

Many people use the terms verification and validation interchangeably without realizing the difference between the two. Not understanding that difference can lead to many models that do not truly represent a real-world process and lead to errors in forecasting or predicting of the outcomes. In this article, we will explore the meaning, importance, differences and…


Use Monte Carlo Simulation to Manage Schedule Risk

The three critical aspects of a running a successful project include project costs, project scope and project schedule. Since projects contain many sources of variation, all three aspects are prone to not meeting targets. Project managers need to use appropriate tools to manage the variability (or risk) in the project. Critical Path Method Traditionally, project…


Case Study: Using DFSS and DOE to Increase Product Reliability

A medical devices company, developing technology to enable smaller medical devices, launched a substrate development effort as part of a larger-scale technology and product development effort. The substrate development effort involved predicting the stress caused by the laser welding process to ensure product reliability. In this Design for Six Sigma (DFSS) case study, design and…


Using Monte Carlo Simulation as Process Control Aid

Monte Carlo simulations are often used as a powerful tool in the Analyze or the Improve phase of a Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control) project. For instance, Monte Carlo simulations can be used to improve the capability of processes. The Monte Carlo simulations can quantify the expected variation improvement. However, simulations are not…

Simulation Modeling Best Addition to Analysis Toolkit

Because of the rapid growth and increased competition in information technology (IT), business process outsourcing (BPO) and other service sector industries in India, quality and cost of operations have become the major distinguishing factors among such companies. Survival, growth and profits depend on how an organization controls its costs and satisfies its clients or customers….
