Define
When do you use Lean?
When Flow, Inventory, and Time are the issues; When there is a lack of standardization; When employees are empowered
What is DPMO?
Defects per Million Opportunities
Besides VSM, SIPOC, and Process Mapping, name three other analysis tools
Spaghetti Maps, Affinity Diagrams, Takt Time
What is PDCA
Plan Do Check Act
What is the goal of the Control Phase?
It ensures that the improvements to the process, once implemented, will be sustained, and that the process will not revert to its prior state.
What are CTQs?
Key measurable characteristics from the voice of the customer (Critical to Quality)
What does Standard Deviation measure?
of variability (dispersion) that is the positive square root of the population/sample variance OR measures the deviation from the mean, which shows the central tendency and the variation from the mean
Name the three steps of the Analyze Phase
Establish Current Process Capability, Define Performance Objectives, Identify Variation Sources
What is meant by a "Pilot Solution"
Run a real world test, and incrementally correct to find larger solution.
What is a simulation?
A means of experimenting with a detailed model of a real life system to determine how the system will respond with changes in its structure
When an organization is at Six Sigma, how many errors per million does it have?
3.4
Name Four of the Seven Quality Tools
Check Sheet, Cause & Effect Diagram, Flow Chart, Pareto Chart, Histogram, Scatter Plot, Control Chart
What are the steps of Analysis Planning?
Generating Xs, Narrowing Xs, Validating the Vital Few Xs
What are three tools to improve flow?
5S, Constraint Management, Level Loading / Takt Time, Pull Systems, Lot Size Reduction, Spaghetti Mapping
What tool ensures each person uses the same method regularly to meet an objective?
Standardized Processes
What are three ways to map?
Value Stream Mapping; SIPOC Analysis; Process Mapping; Spaghetti Mapping; Flow Charting
What is Continuous Data and what is Discrete Data
Continuous: Actual times, actual deviations, ratings across a list
Discrete: met specifications or not, on time or not, Yes/No
Name three charting methods used in Analyze
Histograms, Time Charts, Run Charts, Pareto Charts, box plots, Simple Regression
What is the goal of Error-proofing?
The use of solutions and improvements that either completely prevent or reduce the risk of a failure occurring by eliminating the root cause OR detect a failure soon after it has occurred.
Why use a Control Plan?
Provides an institutional memory of the status of a process and the measurements that define it.
What are the steps in the Define Stage?
Identify CTQs; Develop Team Charter; Define process map
What does SIPOC stand for?
