I need a I-MR control chart created out of this evaluation ….

Calculate the defined process metrics including variation and process capability.

Develop and display a control chart for the process.

From start to finish manufacturing of the car computer processing system takes a total of 10 business days to process a item and a additional 2-4 business days to go thru quality inspections. Items are processed on a assembly line the items take 20 hours to create and go through its process, Because the product must go through 4 different assembly lines to complete its manufacturing. Once items are complete, they are sent to the line for quality based on orders received. Items are then moved to a line for quality control checks where they sit for 24-48 hours then are moved to a final quality control check before for another 24-28 hours before being shipped out to customers.

In my current company it is a manufacturer company so by forecasting improving the process flow of high demand items and reducing focus on lower demand items. This would improve the flow of items getting to customers reducing returns caused by items not getting there quick enough. Lastly the Six sigma process allows the company to search for inefficiency and quality decreasing area of bottleneck in production also reducing returns and increasing customer satisfaction.

Evaluation of Control Chart and Process Metrics

Developing a control chart, we first need to identify the important process parameters that help the quality of the items being produced. We collect data like production time in days or hours, end to end manufacturing and complete order time. The process variation is related to different reasons, which are expected or unexpected. Things like machines not working properly, products not passing quality check and possible issues with transportation such as weather or transport breakdowns or accidents. One must understand the data being computed to use Six Sigma effectively. Six Sigma’s goal is to remove variations and bottlenecks, communicate clearly and train team members, be flexible and responsive and to find the problem and focus on it.
