A natural gas processing company has had problems in its distribution channel and% of defective products. The containers they use to distribute are transportation tanks fed by pipes by land and sea, distributed by trucks. The company's gas production, transmission and distribution process is mapped in the following image:

Makes a flow chart of the gas production process until it is delivered to the end customers. The leader of the high performance team of the quality area carried out a root cause analysis with his work team and the following causes resulted from it: 1. Preparation of services (electricity, hot water, etc.). 2. Low inventory levels. 3. Remove inventory directly from the pipe without an eviction order. 4. Specific volume not met. 5. Incorrect reading of scales. 6. Incorrect sequence of invoices. 7. Lack of coordination between forklifts. 8. Failure to prepare equipment before starting work. 9. Unusual worker behavior. 10. Poor tools and equipment. 11. Order registered in a confusing or illegible way. 12. Poor working conditions (e.g. weather).

Make a diagram to visualize precisely and grouped the causes (Minitab)

Continuing with the root cause analysis, the leader collected the following information:

Table 2. Frequency of errors per cause.

• Develop a diagram that helps to better visualize the causes with their frequency and analyze: What conclusion would you present to the work team?

To counteract the first problem (Preparation of services)it is hypothesized that the sealing temperature of the packer, the temperature of the cooling bar and the gas not suitable in the mixture are related to each other and cause a large part of the defects. We have the following data:

• Develop an analysis to define the relationship between the variables.What practical conclusion would you present to the team?
