Yellow belt 6 sigma Questions With Complete Solutions

What is beta testing? - ANS Beta testing is the act of implementing a new idea, system, or product with a select group of people or processes in as controlled an environment as possible. What is the purpose of beta testing - ANS The purpose of beta testing is to reduce the risks and costs inherent in launching an unproven product or system to a widespread audience. What is 6 sigma? - ANS Six Sigma, or 6σ, is both a methodology for process improvement and a statistical concept that seeks to define the variation inherent in any process. What is the premise of 6 sigma? - ANS The overarching premise of Six Sigma is that variation in a process leads to opportunities for error; opportunities for error then lead to risks for product defects. Product defects—whether in a tangible process or a service—lead to poor customer satisfaction. What do 6 sigma reduce - ANS the Six Sigma method ultimately reduces process costs and increases customer satisfaction. What is the disadvantage of launching ideas into beta—or to an entire population--without going through a Six Sigma methodology? - ANS organizations can experience unintended consequences from changes, spend money on ideas that don't end up working out as planned, and impact customer perceptions through trial-and-error periods rife with opportunities for error. How does 6 sigma help with decision making? - ANS organizations can identify problems, validate assumptions, brainstorm solutions, and plan for implementation to avoid unintended consequences. By applying tools such as statistical analysis and process mapping to problems and solutions, teams can visualize and predict outcomes with a high-level of accuracy, letting leadership make decisions with less financial risk. Technically, in a Six Sigma process - ANS there are only 3.4 defects per million opportunities. 6 sigma in percentages - ANS means 99.99966 percent of the products from a Six Sigma process are without defect. At just one sigma level below—5σ, or 99.97 percent accuracy - ANS processes experience 233 errors per million opportunities. How to calculate sigma levels - ANS # of opportunities - # of defects) # of opportunities. X 100 = Yield. 6 sigma aims to reduce - ANS Time Defects Variability What are the two methodologies of 6 sigma - ANS DMAIC DMADV Which 6 sigma methodology is used in manufacturing or production side of a product or service, - ANS DMAIC What are the DMAIC stages? - ANS Define - address the identification of specific processes to be examined Measure - record data and use metrics to track effectiveness and evaluate efficiencies Analyze - utilize critical thinking skills to review data and clarify goals Improve - create changes in business processes geared toward improvement and better alignment with corporate goals Control - build a system of checks and adjustments for ongoing improvement in production processes What are the DMADV stages? - ANS Define - address customer needs in relation to a product or service Measure - involve the use of electronic data collection to measure customer needs, response to product, or review of services Analyze - utilize metrics to evaluate areas where product or service can be better aligned to customer goals and needs Design - overlap the improvement of business processes that streamline corporate goals to best meet client and customer needs Verify - build a system of tests and models to check that customer specifications are being met through on-going improvements Which 6 sigma methodology is most applicable to examining and improving the customer relations side of a company, - ANS DMADV Which 6 sigma methodology is used in the creation of a new product? - ANS DMADV Which 6 sigma methodology is most commonly used? - ANS DMAIC Who created 6 sigma and when - ANS Six Sigma was developed by Bill Smith in 1986. Then an engineer at Motorola aimed to help improve the company's devices which didn't meet the quality standards at the time. He based the approach on statistical and quality control methods taught by Walter Shewhart, Ronald Fisher, and Edwards Deming. What is VOC in 6 sigma? - ANS Voice of the customer Which phase is VOC found - ANS Define phase Define VOC - ANS Voice of Customer is the customer's voice, expectations, preferences, comments, of a product or service in discussion. It is the statement made by the customer on a particular product or service. What is Value Stream - ANS A value stream is all the steps (both value added and non-value added) in a process that the customer is willing to pay for in order to bring a product or service through the main flows essential to producing that product or service. What is value stream mapping? - ANS Value stream mapping (VSM) is defined as a lean tool that employs a flowchart documenting every step in the process. Many lean practitioners see VSM as a fundamental tool to identify waste, reduce process cycle times, and implement process improvement. What does ANOVA stands for - ANS Analysis of Variance. What does CAPA stands for - ANS Corrective Action and Preventive Action. What does COPQ stand for? - ANS Cost of Poor Quality. What does CTQ stand for? - ANS Critical-to-Quality. What does DFSS stand for? - ANS Design for Six Sigma. What is the DOWNTIME acronym? - ANS Defects, Overproduction, Waiting, Non-utilized Talent, Transportation, Inventory Excess, Motion Waste, Excess Processing.
