I've done whatever I want

Chapter 35PPM3.4
After get off work that night, the three of them turned the 8th dormitory 519 into a bar and a KTV box.

While drinking Tsingtao beer, they ate the peanuts and stewed vegetables they had just bought, and sang a few songs to Xiaowei from time to time. On the days of part-time work, such a gathering of workers is like a fairy life.

"Xiang Gong, do you know Six Sigma?" Questions lingered in the boy's mind during the day, and he was eager to understand and master this tool in order to stand out in his future work.

If there were no differences between men and women, the young man would definitely seek advice from He Silian.Besides, they were not familiar yet, and he was afraid of disturbing her.

Since Holstein understands Six Sigma, it stands to reason that Xiang Gong should also know that they are quality engineers.

"Young man, this is advanced. If you want to learn Six Sigma, you must at least have a university background. It doesn't matter if you don't know calculus, but you must understand mathematical statistics and probability theory. If you don't understand these knowledge, I advise you to give up. With this idea, if you learn the seven techniques well, you can go horizontally at the technician level." Sure enough, Xianggong knew about Six Sigma, and when he mentioned this tool, he immediately became very unpredictable.

However, he must have underestimated Xin Tong, and felt that the high school culture of this young man was too ambitious when talking about Six Sigma.

The young man didn't care about it, on the contrary, he was amused as soon as he heard it. Aren't mathematical statistics and probability theory the knowledge of advanced mathematics?As for?In his previous life, he knew this knowledge like the back of his hand.

"Xiang Gong, mathematical statistics and probability theory are just tools, not that advanced!" the young man said confidently.

"Little brother, don't brag!" Xiang Gong said solemnly.

The boy immediately talked with him about the Poisson distribution and the regression equation, which stunned Xiang Gong: "Little brother, you are so talented, I don't know Taishan with my eyes!"

"Compared to Six Sigma, these are all pediatrics!" The boy said, taking a sip of his wine.

"You know probability theory, learning Six Sigma is very easy!" Xiang Gong patted the boy on the shoulder.

"Please give me more advice!" said the boy, clasping his hands.

"To be honest, my university degree is mixed. I know little about mathematical statistics and probability theory. My understanding of the tool Six Sigma is also very superficial. In 1986, Bill Smith of Motorola Corporation proposed the Six Sigma concept. Sigma is the standard deviation in mathematical statistics. According to Smith’s vision, as long as Six Sigma is achieved, the defect rate of the product can reach 3.4PPM level!”

Although Xiang Gong has not studied it intensively, Mingyueguang's quality department often discusses this advanced tool, so that he can talk endlessly about Six Sigma knowledge on paper.

"PPM? What is PPM?" the boy asked. Mingyueguang's yield statistics were all based on percentages, and no one had ever mentioned PPM to him.

"PPM means Parts Per Million. When your product reaches 3.4PPM, it means that the production yield can reach [-] parts per million!" Xiang Gong said while spitting at the mouth. .

"Oh my God!" After hearing Xiang Gong's explanation, the boy was stunned.

The current best yield level in the bonding process is around 99.6%, which means a loss of 4000PPM.

From 4000PPM to 3.4PPM, there is no end to improvement.

"Xin Gong, it's off-duty time now, don't discuss those work topics!" Zhu Tianli listened annoyed.

"Yes, during off-duty time, let's talk about the basketball league! Both of your departments have defeated our quality department. It is the greatest misfortune to be in the same group as you." Xiang Gong took a sip of his wine and said with emotion.

"Who told you not to play?" Zhu Tianli glanced at him.

"Brother, I won't give up when fishing. Just let me go when playing!" Xiang Gong said with a smile.

"The champion of Group B is the Human Resources and Administration Department. Guess which team will be the champion of Group A?" Zhu Tianli asked with narrowed eyes.

"I guess it must be the FOL engineering department! Your production department is not at the same level as them, and you will lose miserably!" Xiang Gong said with a smile. Although in his heart, the EOL production department would definitely win, but he just didn't want Fatty hapiness.

"Have a vision, come! Cheers!" said the boy, raising his glass.

The last match of Group A took place on the last day of November.

The two teams facing each other are the first team of the engineering department where Xin Tong belongs and the second team of the production department where Zhu Tianli belongs.

This is also the last group match of the first basketball league.

At present, these two teams have won two consecutive victories, and they have already secured the qualifying places. What they want to fight for is the first place in the group.

"We played much better than expected. Before the game, no one was optimistic that we would qualify. We played with the spirit of the department!" Luo Gaogong encouraged everyone at the pre-match mobilization meeting.
