CHAPTER 11
SIX SIGMA AND PROCESS IMPROVEMENT

TRUE/FALSE QUESTIONS

1. In Six Sigma, a problem is defined as a deviation between what should be happening and what actually is happening that is important enough to need correcting. Answer: T AACSB: Analytic Skills

2. Half the tolerance is equal to the distance from the target to the upper specification limit. Answer: T AACSB: Analytic Skills

3. A change in the quality level from 3-sigma to 4-sigma represents a five-fold improvement. Answer: F AACSB: Analytic Skills

4. 3.4 defects per million opportunities can occur with a quality level of 5-sigma if the mean shift is 0.5 standard deviations of the target. Answer: T AACSB: Reflective Thinking Skills

5. A Six Sigma quality level means that the difference between the upper and lower specification limits is six standard deviations. Answer: F AACSB: Analytic Skills

6. Six Sigma represents a quality level of 3.4 defects per million opportunities when the process mean is held exactly on target. Answer: F AACSB: Analytic Skills

7. Unstructured problems require more creative approaches to solving them than structured problems. Answer: T AACSB: Reflective Thinking Skills

8. The expectations of customers that matter most to them are known as “critical to quality” issues in Six Sigma terminology. Answer: T AACSB: Analytic Skills

    The Six Sigma, leading edge R&D and exceeding ISO 9000 standards are what define the attitude and capability of Riordan Manufacturing. Six Sigma is a "quality improvement program used for identifying and eliminating defects, waste and quality control problems in manufacturing". The goal of six sigma is hand-in-hand with that of Riordan's, to achieve the highest levels of quality. "A sigma is a statistical term for the standard deviation of a set of data, so six sigma refers to six standard deviations", with the "basic premise behind Six Sigma is that of a company can measure the amount of defects in a process, the company can systematically determine how to eliminate them, getting as close to zero defects, or perfection, as possible" (Beginners Guide Staff, 2005).…

    "...Six Sigma is a highly disciplined process that helps us focus on developing and delivering near-perfect products and services. Why 'Sigma'? The word is a statistical term that measures how far a given process deviates from perfection. The central idea behind Six Sigma is that if you can measure how many 'defects' you have in a process, you can systematically figure out how to eliminate them and get as close to 'zero defects' as possible. To achieve Six Sigma Quality, a process must produce no more than 3.4 defects per million opportunities. An 'opportunity' is defined as a chance for nonconformance, or not meeting the required specifications. This means we need to be nearly flawless in executing our key…

    Six Sigma has been picking up pace in the industry; on the other hand, scholars have directed little research on this developing wonder. Understanding Six Sigma first requires giving a theoretical definition and distinguishing a fundamental theory behind it (Schroeder, 2007). Hence, let’s critique the differences between this new powerful tool Six Sigma and its previous versions like Total Quality Management (TQM).…

    The term Six Sigma originated from terminology associated with manufacturing, specifically terms associated with statistical modeling of manufacturing processes. The maturity of a manufacturing process can be described by a sigma rating indicating its yield or the percentage of defect-free products it creates. A six sigma process is one in which 99.99966% of the products manufactured are statistically expected to be free of defects (3.4 defective parts/million), although, as discussed below, this defect level corresponds to only a 4.5 sigma level. Motorola set a goal of "six sigma" for all of its manufacturing operations, and this goal became a by-word for the management and engineering practices used to achieve it.…

    Framework for Ethics

    If standards are set aside for short-term gain, they suffer in the end. Ethical standards must therefore be absolute. The right decisions made by a company may not always be the most lucrative. Having ethical standards though, has given most business corporations the tools to make and follow the right decisions. Six Sigma is a set of strategies used by companies for quality improvement. In many organizations, Six Sigma simply means a quality measure that strives for perfection (Eckes, 2004). It is a data-driven approach and process for doing away with defects. This is done through driving towards six standard deviations between the nearest specification limit and the mean. To realize Six Sigma, the process must produce less than…

    In this case, the Six Sigma philosophy and methods to produce no more than 3.4 defects out of every million units will be used in combination with DMAIC a systematic projected-oriented cycle process to achieve customer satisfaction levels. The plan will also use a number of Six Sigma’s analytical tools such as: flowcharts, check sheets, opportunity flow diagram and failure mode and effect analysis (FEMA) to properly detect any defects that could occur during the production process (Jacobs & Chase, 2011, p.…

    Wal-Mart has difficulty developing and implementing a process that can improve the product material quality since there are so many vendors, manufacturers and international companies involved. They need to implement a set of standards that every company needs to adhere to by setting acceptable standards that must be met across the board whether the company is a local business or a foreign company. Most of the material defective products come from overseas. The process that can afford the opportunity to fix this dilemma is the process known as Six Sigma. This method is designed to manage process variations which cause defects. The concept of this process is to take an already established defect variation and use a step-by-step chain of events that will work towards managing variation in order to eliminate the established acceptable defects. The purpose behind selecting this process is because Six Sigma has the ability to provide high-performance, reliability, and value to the products Wal-Mart purchases which offers a better quality product to the customer. The process was originated by Bill Smith while working at Motorola in 1986. The process was initially defined as a metric for measuring defects and improving quality which would set precedence and standardize defective measures for all vendors and suppliers for Wal-Mart.…
