Introduction to Lean Six Sigma Flashcards
(34 cards)
What is Lean Six Sigma?
Lean Six Sigma is a methodology that combines Lean manufacturing principles and Six Sigma techniques to improve performance by systematically removing waste and reducing variation.
What are the primary goals of Lean Six Sigma?
The primary goals are to improve processes to produce high-quality products and services efficiently, with minimal waste and variation.
How does Lean Six Sigma emphasize decision making?
Lean Six Sigma emphasizes making decisions based on data and statistical analysis rather than assumptions or guesses, ensuring that process improvements are based on solid evidence and can be measured for effectiveness.
What is the DMAIC methodology in Lean Six Sigma?
DMAIC stands for Define, Measure, Analyze, Improve, Control. It is a data-driven quality strategy for improving processes.
What does DMADV stand for and when is it used?
DMADV stands for Define, Measure, Analyze, Design, Verify. It is used for designing new products and processes to meet customer needs and process capability.
What are Critical to Quality (CTQ) characteristics?
CTQ characteristics are the attributes most important to the customer, which must be met to satisfy their needs.
What is meant by ‘defects’ in Lean Six Sigma?
Defects refer to failing to deliver what the customer wants, leading to products or services that do not meet quality standards.
Define ‘process capability’.
Process capability is the ability of a process to produce outputs that meet specifications or customer requirements consistently.
What are the ‘seven muda’ (wastes) in Lean?
The seven muda are defects, over-production, waiting, non-utilized talent, transportation, inventory, motion, and extra-processing.
List the Lean principles.
The Lean principles are Value, Value Stream, Flow, Pull, and Perfection.
What is the origin of Six Sigma?
Six Sigma was developed by engineer Bill Smith while working at Motorola in 1986.
What is the goal of Six Sigma?
The goal of Six Sigma is to improve processes to the point where they produce fewer than 3.4 defects per million opportunities (DPMO).
Name a key milestone in Six Sigma history.
A key milestone is General Electric’s adoption of Six Sigma in the 1990s, which significantly boosted its popularity and implementation.
What is statistical process control (SPC)?
SPC is a method of quality control which uses statistical methods to monitor and control a process.
What is a significant application of Six Sigma?
A significant application is its use in manufacturing to reduce defects and improve quality.
What is Total Quality Management (TQM)?
TQM is a management approach to long-term success through customer satisfaction, involving all members of an organization in improving processes, products, services, and culture.
What is Lean methodology?
Lean is a systematic method for waste minimization within a manufacturing system without sacrificing productivity.
Name a principle of Lean.
One principle is the focus on improving overall customer value.
What is the difference between Lean and Six Sigma?
Lean focuses on eliminating waste and improving flow, while Six Sigma focuses on reducing variation and improving quality.
What is Kaizen?
Kaizen is a Japanese term meaning “continuous improvement” involving everyone in the organization from the CEO to the assembly line workers.
Define the Lean principle of “Value”.
Value is defined from the perspective of the customer and involves only what the customer is willing to pay for.
What is a Value Stream?
A value stream includes all the steps (both value-added and non-value-added) in a process required to create a product or service.
What does “Flow” mean in Lean?
Flow refers to the smooth progression of products or services through the value stream without interruptions, delays, or bottlenecks.
What is the Lean principle of “Pull”?
Pull means producing items only when there is demand from the next step in the process or from the customer reducing overproduction and excess inventory.
