Summary Introduction
Case summary:
TG from country S is the third largest telecom company. Its service offering includes landline, cell phone, broadband and TV services. TG has 256 million customers worldwide, the majority of which are cell phone users.
T’s mobile communication subsidiary M has 16 million customers and 4000 employees. M implement Six Sigma and Lean philosophy in 2002, and up till 2011 it has completed more than 200 projects focusing on cost reduction, service level increases, process reengineering, quality assurance and productivity improvement. This resulted in cumulative savings of $245 million. Projects are now executed with focus on three key initiatives – improvement community, workshops, and inheritance stage.
Via this process, M has trained several Champions, Black Belts and Green Belts. The improvement community consists of Black and Green Belts that conduct training on quality issues and mentor other Black and Green Belts in the usage of quality tools. The improvement community also organizes workshops for new project development.
After a team completes the DMAIC stage, the quality team evaluates team performance, followed by an inheritance period of one year. A project heir is assigned – the best performing Green Belt from the team. The heir is responsible for “improve” and “control” sections of DMAIC.
To determine: Another global company that has successfully implemented Six Sigma and discuss its experiences.

Verizon Manufacturing Company spent $408,000 in 2019 to inspect incoming components. Of the $408,000, $244,000 is fixed appraisal costs. The variable inspection cost is $0.20 per component. It takes two components for each finished product. Internal failure costs average $88 per failed unit of finished goods. In 2019, nine percent of all completed items had to be reworked. External failure costs average $216 per failed unit. The company's average external failures are three percent of units sold. The company manufactures all units as ordered and carries no materials inventories. Seeking to decrease its total cost of quality (COQ), Verizon contracted Quality-is-Free Consultants, Inc. (QIFC) to study ways to improve product quality and to reduce costs. Upon completion of the study, QIFC recommended automatic inspection equipment that requires a $64,000 annual cost for training and $158,000 for equipment rental and maintenance. The new equipment will eliminate $44,000 of the fixed…

Challenge
Like most food & beverage manufacturers, this customer utilizes steam in the production of several product lines. Ensuring the smooth operation of its steam system is an important aspect of its maintenance strategy due to the system’s potential impact on the plant’s overall operating costs; a poorly functioning steam system can significantly reduce uptime, energy efficiency, and the safety profile of a given plant. With steam trap failure representing one of the highest risks to a steam system, maintenance of these mechanical relief devices is of paramount importance.
Although the customer followed the best practices for…

- A production operation is making 150 units of a product by engaging five workers for 300 hours. However, 40 percent of the units appear to have various quality problems, and the company decides to sell them as seconds at a price of £50 each when a normal unit is sold for £150. To improve the situation, several initiatives are proposed, including a scheme where, for every improvement, 50 percent will be given to workers and the other 50 percent will be held by the company. This results in a significant drop in defects as now only 10 units are faulty out of an output of 130 units. 1. Compare the productivity after Bonus with the initial productivity. 2. Determine the appropriate bonus per hour for the workers under the bonus scheme if the cost per piece is £70 both before and after the scheme.arrow_forwardGE adopted Six Sigma from Motorola in 1995, Which of the following is not an advantage of using Six Sigma : Select one: A.

- Because of the poor quality of its cars, Hyundai watched its U.S. sales drop from 264,000 cars to 90,000 cars in just two years. Hyundai cars ranked 26th out of 35 car brands in terms of initial car quality as measured by the influential J.D. Power Initial Car Quality survey. With $6.6 million in debt, a $1 billion investment for a new manufacturing plant in Alabama, and the company’s first-ever loss, Hyundai’s new chairman, Chung Mong Koo, declared that improving quality was the only way to fix the company.The challenge for Chung was to get his managers to put quality, and not costs, first. So he sent a visible, meaningful message that poor quality would no longer be tolerated. During one plant visit, Chung demanded to see under the hood of a car on the production line. He was furious when he saw loose wires, tangled hoses, bolts painted four different colors - tremendous deviation from what the engine compartment was supposed to look like.

- An automobile manufacturer plans to spend one billion dollars to improve the quality of a new model. The manufacturer expects the quality improvement program to eliminate the need for recall and reduce the costs for warranty repairs. The manufacturer’s experience has been, on average, 1.5 recalls for each new model at a cost of $300 per vehicle per recall. The average cost per recall, if one is needed, is expected to increase by 10% for the new model. Costs for other warranty repairs are expected to decrease from $200 to $80 per unit. Sales of the new model were expected to be 500,000 units without the quality-improvement program. The firm believes that the proposed, well-advertised quality program expected to cost an additional $50 million will increase total sales to 650,000 units. The gross profit per unit on the new model sold is $5,000. Required: Would you recommend the proposed quality-improvement program? Please show all your computations to support your answer.arrow_forwardAn automobile manufacturer plans to spend one billion dollars to improve the quality of a new model.
