Part 4 Flashcards
Lean is based upon 2 key principles:
Removal of irregularity Removal of irrelevance
Lean enterprise eliminates:
Waste Non value-added activities
The success of Six Sigma and Lean is based on:
Building a culture of support
The Seven Elements of Waste are:
Transport, Inventory, Motion, Waiting, Over Producing, Over Processing, Defects
Formal document used to summarize key deliverables and information for a Six Sigma project.
Project charter
The center point of a range of values. For a data set, it may be thought of as the “middle” value.
Median Average
What is this an Example of?
Normal distribution graph, where 0 is the mean average point
Used to determine the strength of a relationship between data output and input.
Regression analysis
Designed to improve the process when the apparent variation is caused by variations in the measuring system.
Measurement Systems Analysis (MSA)
This bias occurs when some members of the population are inadequately represented in a sample.
Under-coverage bias
___________ is a sampling from a population in which the selection of a sample unit is based on chance. Every element of the population has a known, non-zero probability of being selected.
Random Sampling
Bias that results from problems in the measurement process. Bias due to measurement error can occur with a poor measurement process.
Response bias
Used to determine whether a process is capable of consistently achieving the required specifications.
Process Capability Study
Allows you to evaluate if a project or proposed process improvement calculation is statistically significant, or if the same thing could have occurred by random chance.
Hypothesis testing
Systematic series of tests used to determine relationships of x and y variables that affect a process and response.
Design of Experiments
Used to monitor processes and may be applied to production or business processes. Uses statistical methods to ensure that the process is stable and monitor the processes for timely identification of special causes.
Statistical Process Control
Could possibly be the most important part of the entire DMAIC methodology. Helps verify that the Voice of the Customer is being met by verifying improvement processes, documenting procedures, and updating standard operating procedures and policies.
The control plan
One of the key requirements for introducing any Six Sigma change is gaining:
Buy-in of the business and the people impacted
Introducing a Six Sigma process change overlaps with a considerable amount of
Change Management
LEAN always asks?
“How can we get Better?”
The Main idea behind the Lean Process is:
To get the most streamlined process within a produciton environment. It eliminates waste and non-value added activities.
