The lean methodology is a powerful approach used in Continuous Process Improvement (CPI) to identify waste and inefficiencies within processes. Lean focuses on maximizing value for customers while minimizing waste, which is defined as anything that does not add value to the final product. By applying lean principles, organizations analyze their workflows to pinpoint non-value-adding activities—often referred to as waste—which can include excess inventory, overproduction, waiting time, unnecessary transportation, and defects.

Through techniques such as value stream mapping, teams can visualize and understand their processes thoroughly, identify areas for improvement, and implement solutions to streamline operations. This leads to more efficient processes and better resource utilization, ultimately improving overall productivity and customer satisfaction.

While other approaches like Agile development, traditional project management, and time and motion studies have their own applications within process and project management, they do not specifically target waste identification and reduction in the same manner that lean does. Agile focuses more on adaptability and iterative development, traditional project management emphasizes structured planning and execution, and time and motion studies are more of a measurement tool rather than a holistic approach to process improvement.
