Lean Six Sigma Black Belt Certification - Mock Test

Explanation
Six Sigma is a methodology that focuses on reducing defects and variations in processes, ultimately leading to improved customer satisfaction and increased profits. By implementing Six Sigma principles and tools, organizations can identify and eliminate sources of customer dissatisfaction, resulting in improved product quality, on-time delivery, and overall customer experience. This, in turn, leads to higher customer satisfaction levels and increased customer loyalty, which ultimately translates into higher profits for the business. Therefore, the correct answer is Customer Satisfaction and Profits.

Explanation
Green Belt professionals are responsible for executing small to mid-sized Six Sigma projects. They have a good understanding of the Six Sigma methodology and tools, and they work under the guidance of Black Belt professionals. Green Belts are typically subject matter experts in their respective areas and play a crucial role in implementing process improvements within their organizations. They are trained in the DMAIC (Define, Measure, Analyze, Improve, Control) methodology and use statistical analysis to identify and solve problems. Green Belts are an important part of the Six Sigma team and contribute to the overall success of the project.

Explanation
The defect level associated with 3 sigma standard is approximately 66,807 ppm (parts per million). This is calculated as 3 standard deviations from the mean in a normal distribution, which covers about 99.73% of the data, leaving approximately 0.27% or 2,700 parts per million as defects. Therefore, the closest option is 68,807 ppm.

Explanation
New Product Development is a cross-functional business process because it involves multiple departments and functions working together to develop and launch a new product. This process typically includes activities such as market research, product design, prototyping, testing, marketing, and sales. It requires collaboration and coordination between departments like research and development, marketing, manufacturing, and finance.

Explanation
The mean and median both help to convey where the data is centered. The mean is the average of all the data points and is influenced by extreme values, while the median is the middle value of the data set and is not affected by extreme values. Therefore, both measures provide information about the central tendency of the data.

Explanation
If you get a longer working time between re-charges than expected from your mobile phone battery, it would fall under the category of a performance feature according to the Kano Model. This is because the longer battery life exceeds the customer's expectations and enhances the overall performance of the phone.

Explanation
Internal Failure costs refer to the costs incurred within an organization due to defects and errors in its processes and products. These costs include the expenses associated with identifying and rectifying defects, reworking faulty products, and addressing customer complaints. Therefore, defects and rework are examples of Internal Failure costs. Inspection and audits, warranty and returns, and purchasing and accounting are not examples of Internal Failure costs as they are related to other types of costs such as Appraisal costs, External Failure costs, and Prevention costs respectively.

Explanation
Lean is the correct answer because it is a framework within the Six Sigma methodology that focuses on eliminating waste and improving efficiency in business processes. It aims to increase speed and agility by streamlining operations and reducing non-value-added activities. Lean principles include continuous improvement, just-in-time production, and reducing defects and errors. By implementing Lean practices, organizations can optimize their processes and deliver products or services faster, resulting in improved customer satisfaction and competitive advantage.
