Lean Six Sigma Green Belt Certification Exam Test Questions And Answers Verified 100% Correct The Pareto Principle (80/20 Rule) - ANSWER Says that 20% of the causes lead to 80% of the effects. Or, the vital few inputs drive the majority of the outputs. Pareto Chart - ANSWER A graphical representation of data elements - usually inputs or causes - in a ranked bar chart. Those bars are arranged in order of height, with the highest on the left and the lowest on the right. General customer feedback - ANSWER Often obtained through feedback forms, customer complaint records, and passive information gathering via websites or social media. -General Voice of Customer (VOC) feedback is used a smoke alarm. The 5 Whys - ANSWER a brainstorming tool that asks increasingly granular why questions about a problem or process, seeking to understand the actual root or cause of the problem. A strong problem statement covers - ANSWER - When? - Where? - What? - How many? - What is the magnitude? Process - ANSWER A collection of tasks, steps, or activities that are performed, usually in a specific order, and result in an end product such as a tangible good or provision of a service. 4 Layers of the Process - ANSWER - The steps - Processing time - Interdependencies - Resources and assignment SIPOC - ANSWER Suppliers, Inputs, Process, Outputs, Customers ISO 9000's Definition of Quality - ANSWER the degree to which a set of inherent characteristics fulfills requirements Critical to Quality characteristics (CTQ) - ANSWER the factors or parameters that are major drivers of quality within an organization or process. Usually, CTQs are key characteristics that can be measured; where the performance of said metric provides information about whether or not the customer will be satisfied Cost of Poor Quality (COPQ) - ANSWER Costs associated with external failures and costs associated with internal failures. Costs of Nonconformity - ANSWER External and internal failures. They are the expenses that occur when outputs do not conform to critical to quality requirements. Cost of Quality - ANSWER Includes the cost of poor quality and the cost of good quality. Includes prevention and appraisal costs. Cost of Conformity - ANSWER E.g. prevention and appraisal costs. Expenses related to ensuring outputs conform to critical to quality requirements. Six Sigma Project Team Members - ANSWER - Sponsors and champions - Business or process owners - Six sigma leaders - Project managers - Timekeeper - Scribes or minute-takers DMAIC - ANSWER Define, Measure, Analyze, Improve, Control - Often used for solutions or processes that already exist DMAIC: Define - ANSWER Identify the problem, define requirements for the project, and set goals for success. DMAIC: Measure - ANSWER When teams use data to validate their assumptions about the process and the problem. Gathering data and measuring it in a way that it can be analyzed. DMAIC: Analyze - ANSWER Teams develop hypotheses about causal relationships between inputs and outputs and between Xs and Ys, they narrow causation down to the vital few, and they use statistical analysis and data to validate the hypotheses and assumptions made so far. DMAIC: Improve - ANSWER Teams work to standardize solutions in preparation for rolling improved processes to daily production and non-team employees. Teams also start measuring results and lay the foundation for the controls that will be built in the last phase. DMAIC: Control - ANSWER Where loose ends are tied and the project is transitioned to the daily work environment. DMADV - ANSWER Define, Measure, Analyze, Design, Verify. -Often used to fill a need with a solution that doesn't yet exist. Project charter details - ANSWER - Business case: A short statement that provides a reason the project should be undertaken. You would build on that basic financial statement to explain why, specifically, the loss of money, efficiency, or quality is important to customers, employees, or the organization. - Scope: The exact parameters for the project. - List the stakeholders: Helps the team members remember who and what they will impact in addition to end customers. - Team member roles - Milestones - Measurement of success: If a team can covert a CTQ to a measurement, they can understand what major metrics determine success for the project - Expected financial benefits: Estimated savings or increase in revenue Gantt Chart - ANSWER A bar chart of schedule information where activities are listed on the vertical axis, dates are shown on the horizontal axis, and activity durations are shown as horizontal bars placed according to start and finish dates. Failure Mode and Effects Analysis (FMEA) - ANSWER a systematic process for identifying potential design and process failures before they occur, with the intent to eliminate them or minimize the risk associated with them Discrete data - ANSWER Categorical in nature, qualitative or binary data. Falls into 3 categories: ordinal, nominal, and binary. -Relates to Binomial and Poisson distributions Ex: The team might create a tick sheet, having someone make a mark every hour to note whether the temperature was in the 40s, 50s, 60s, 70s, etc. Continuous data - ANSWER Quantitative data, measured in units. Provides more information than discrete data, is typically more time-consuming to collect, more precise, and lets teams remove variation and errors inherent in estimation and rounding.
