1. For what purpose does Autoliv collect data? lGive some of the examples of the types of data collected. They collect data to improve their products and processes to streamline operations, drive out inefficiencies, and reduce cost. 2. Explain why Autoliv must rely on sampling for data collection. It would be impossible to test every piece that comes out of the machines used sampling gives pieces from each machine for testing on various molded parts. Each piece tested provides information for the parts lot being produced from the machines. That is part of the daily samples required by the customer. Also, as a manufacturer, you want to know that your process is staying in the same place. , 3. What types of graphs ,r' charts can Autoliv use to explore the data? Many times they try different types of charts, different types of analysis because they yield different types of results. They use histograms to look at the spread of the data. tt allows them to break up the variables into smaller parts to detect problems. They are also trying to detect randomness in the variables. When the graphical data were examined designers and engineers were immediately able to focus on the source of the process 4. Describe how the \"eureka" revealed to Autoliv in the lm was discovered. Theytook the weight data and put them in the context of the time, and also in the context of some other variables they collected and began to see differences, There was a difference between the mold sections these parts came from calied the cavity. That is the Eureka moment. Without data coliection and graphing detecb'ng that the process was moving off the target weight would have been impossible
