Statistical Process Control Methods Process Evaluation Evaluate your process using 1 of the following: . Use the lean concept to nd ways to eliminate waste and improve the process . SPC or Six Sigma to reduce defects or variances in the process Lean and Six Sigma are powerll process improvement methodologies that can be used together or separately to achieve process efciency and effectiveness. Here's how each of them can help eliminate waste and reduce defects: 1. Lean concept to eliminate waste: The Lean methodology emphasizes the elimination of waste in all its forms from a process. Waste refers to any activity that does not add value to the product or service being produced, such as overproduction, waiting, unnecessary motion, defects, overprocessing, excess inventory, etc. Lean helps identify these wastes and develop strategies to eliminate or reduce them. For example, by using Lean concepts, you can eliminate waiting time by organizing the work processes, reduce motion waste by repositioning tools and equipment, and reduce excess inventory by optimizing the supply chain. By identifying and eliminating waste, you can improve process efciency, reduce lead times, and lower costs.

SPC uses statistical tools to monitor and control process variation in real-time to ensure that the process is performing within the desired specications. Six Sigma uses a structured problem-solving approach and statistical tools to identify and eliminate the root cause of process variation, resulting in a signicant reduction in defects and improved process performance. For example, by using SPC, you can detect process variation in real-time and take corrective action to prevent defects. Six Sigma can be used to identify the root cause of defects and eliminate them by improving the process design, reducing variability, and improving process controls. By combining Lean and Six Sigma, you can achieve both process efciency and effectiveness by eliminating waste and reducing defects. This can lead to signicant cost savings, improved customer satisfaction, and increased protability.
