Six Sigma (SS) is now a well-entrenched methodology for performance improvement and comprises highly sophisticated tools targeted at quality improvement or cost reduction initiatives. However, the application of such tools is often not predicated on a foreknowledge or an informed supposition of the potential effects but is instead autotelic. One approach that has helped managers cope with the uncertainty associated with the implementation of an SS project is a simulation, which helps estimate the performance of critical system variables subjected to diverse what-if analyses. System Dynamics (SD) is a widely used simulation technique based on which no work has been performed to estimate the effects of an SS project in an organization. This work presents a holistic SD-based simulation model for an SS project that is based on a previously established technological archetype. The new model is intended to create a foundational template for future high-fidelity studies on the impact of SS projects in an organization.
