What is the objective of the Six Sigma process quizlet?
Introduction to Lean Six Sigma Terms in this set (27)Six Sigma Refers to a product or process that produces only three defects (or errors) out of every million opportunities. Sigma Level Sigma level is a quality metric that measures the level of performance of a process based on the number of defects per million opportunities (DPMO) in that process, compared to the near-perfection level of Six Sigma, which equates to 3.4 defects per million opportunities. Benefits of Six Sigma Customers get more quality, reliability and value. Defect Any failure of a product or service to meet customer requirements. The "customer" may be the external consumer, or may be the next step of an internal process. Philosophy Lean Six Sigma Removing variability from upstream operations that are inputs to a process will yield defect-free outputs Goal Lean Six Sigma Identify the significant inputs, then tackle the root causes of their adverse variability through improved process controls, error-proofing, redesign for manufacturability, and other methods. Y=f(X) Means output (Y) is a transfer function (f) of inputs (X), variability in the inputs causes defects, or errors, in the output. Transformation of inputs by the process into an output is represented by f. Central Activities of a Lean Six Sigma Project Identifying and resolving upstream root causes of variation (defects) Defects Per Million Opportunities (DPMO) When a process is improved to the point to 3 or less defects in each million opportunities, process reaches Six Sigma performance level. Purpose of Lean Six Sigma Business Success defined by: Lean Six Sigma A comprehensive and flexible system for achieving, sustaining and maximizing business success (objective, tangible, bottom-line results). Six Sigma is uniquely driven by close understanding of customer needs, disciplined use of facts, data, and statistical analysis, and diligent attention to managing, improving, and reinventing business processes." Lean Methods Developed to attack the waste associated with the flow of material and information - the velocity, or speed, of a process from beginning to end. Value Stream Map - Purpose Define Current and Desired Future State Value Stream Map - Definition Visual map of the value stream created to show the flow of materials and information. Value stream maps have been widely used as a central component of the Toyota Production System. They include information on takt time (demand rate), inventory levels, changeover times, and manpower. The goal of Value Stream Mapping is to identify the primary process steps and activities that require process improvement. Value Stream Map - DMAIC Alignment Define Takt Time - Definition The time it should take to produce one unit if production is matched to demand. Takt time = net available production time (after breaks) per period divided by average customer demand during that same period. Takt Time - Purpose Line Balancing Takt Time - DMAIC Alignment Define / Measure Little's Law / Theory of Constraints - Definition Little's Law is an equation that expresses the relationship between processing speed, the level of work-in-process inventory, and process cycle time. The equation states: Cycle Time = Items-In-Process / Throughput Volume Per Unit of Time Little's Law / Theory of Constraints - Purpose Reduced Work-In-Process, Reduced Cycle Time
Little's Law / Theory of Constraints - DMAIC Alignment Improve Quick Changeover - Definition Methodology used to reduce the time to execute process set-ups required when changing between different products or services. Lean systems achieve lower inventory levels through small lot sizes, which in turn require Quick Changeovers. See also SMED. Quick Changeover - Purpose One Piece Continuous Flow Quick Changeover - DMAIC Alignment Improve Kanban / Pull Scheduling - Definition System where inventories of downstream operations are replenished by pulling work-in-process inventory on demand from upstream operations as the downstream operations exhaust their inventories. See also Just-In-Time.

physics You are an intern at an engineering company that makes capacitors used for energy storage in pulsed lasers. Your manager asks your team to construct a parallel-plate, air-gap capacitor that will store $100 \text{~kJ}$ of energy. $(b)$ Suppose you have developed a dielectric that has a dielectric strength of $3.00 \times 10^8 \text{~V} / \text{m}$ and a dielectric constant of $5.00$. What volume of this dielectric, between the plates of the capacitor, is required for it to be able to store $100 \text{~kJ}$ of energy? Verified answer
physics An electric field of 260 000 N/C points due west at a certain spot. What are the magnitude and direction of the force that acts on a charge of $$ - 7.0 \mu C $$ at this spot? Verified answer physics In steady flow, the velocity $\overrightarrow{\mathbf{v}}$ of a fluid particle at any point is constant in time. On the other hand, the fluid in a pipe accelerates when it moves from a larger-diameter section of the pipe into a smaller-diameter section, so the velocity is increasing during the transition. Does the condition of steady flow rule out such an acceleration? Verified answer Recommended textbook solutions

The term originally comes from the sigma rating used to statistically rate manufacturing processes in engineering. A six sigma process occurs when no defects are expected in 99.99966% of all chances to produce them.
What is process in Six Sigma quizlet?A six-sigma process: define, measure, analyze, improve, and control. Used for projects in and improving in existing business process. You just studied 84 terms!
Which of the following is the key objective of Six Sigma?The goal of Six Sigma is to reduce variation for optimal quality control. The discipline known as Lean Six Sigma (LSS) blends these two approaches. Refinements to the production process are essential to managing and reducing the 8 wastes analyzed by the Lean method.
What is the Six Sigma process?Six Sigma is a process that makes use of statistics and data analysis to analyze and reduce errors or defects. In this process, the purpose is to improve cycle times while reducing manufacturing defects to no more than 3.4 defects per million units or events.
