Explanation / Answer

In point 10, Dr. Deming is trying to say that, all the poster, motivation slogans, and positive quotes will just increase the cost for the company and it will not impact on the growth of the business. He says that it will instead decrease the productivity of an employee. According to him, it will invest time and money of management and in return will conclude in decrease in productivity.

Slogans are not there in office floor, to look floor more creative, but main reason for all this is to motivate employees. It is a way which says that company cares for you.

In point 14 Dr. Deming is saying that everyone in the company do the work and achieve the goal of the company, in this point he is eliminating the need of management in the company. Without management the company cannot work for its goal and will never get success in future. Management in a company is as necessary as the employees are.

In point 4 Dr. Deming is focusing on cost cutting in the company, however he is again eliminating the risk associated with the cost cutting. For manufacturing companies, cost cutting may involve the use of secondary quality goods, which will impact the overall product quality of the company and will decrease the sales. If the quality of critical material is compromised than it will ultimately results into increase cost of good reason being to overcome the cheap quality you will need to take other measures, which will increase the cost.

He also talks about not to switch to vendors, instead continue using same vendor to enhance relationship, this is actually depends on the variation in the market, if the market need is not satisfied with the old vendor than it is beneficial for the company to move to new vendor. This will take more time to make relationship with new vendor but it will be beneficial in long run as the product quality will not be compromised and will result in increased sales.

4. Discuss the difference between specification limits and control limits? Discuss the pros and cons of establishing either set of limits before the other?

Control limit is something that comes from the process, it will help in determine which process data what will be the control limits, what will be stability of the process, on the other hand, specification limit is based on the customers, what specific limit they estabilish.

The table below contrasts control limits and specification limits: (source - https://www.nwasoft.com/resources/information-center/article/control-limits-vs-specification-limits)
