2000: An international quality standard.
QUESTION
Plan-Do-Check-Act Cycle/Deming Wheel/Shewhart Cycle
Answer:
A cycle of continuous improvement that is repeated indefinitely. Planning involves using
appropriate tools to identify problems or improvement opportunities. Doing involves acting upon
the plan. Checking involves analyzing the actions performed to ensure that goals were achieved.
Acting involves standardizing and documenting the changes, communicating changes to other,
and determining why goals were not achieved.
QUESTION
Seven Tools of Statistical Process Control (SPC)
Answer:
Fishbone diagrams, check sheets, control charts, histograms, Pareto charts, scatter diagrams, and
control charts (classified as flow/run charts).
QUESTION
Check Sheets
Answer:
Used to record data points in real-time at the site where the data is generated; raw data is
collected without interpretation and then depicted using a different statistical tool.
QUESTION
Histogram/Box Chart
Answer:
Shows the frequency of data observations within a preset range of values.
QUESTION
Scatter Plot
Answer:
Displays data as a relationship between two variables; correlations can be drawn based upon the
data. The controlled variable is the independent variable.
QUESTION
Pareto Chart
Answer:
A bar chart that reflects data values in a descending order.
QUESTION
Control Chart
Answer:
A graphical depiction of process outputs where the raw data is plotted in real-time within upper
control limits (UCL) and lower control limits (LCL); this allows one to determine if a process is
stable or trending towards instability and take corrective action before variations result in nonconforming products (see Page 30 for example).
QUESTION
Run Chart
Answer:
Another form of a control chart for processes that have common features, a common scale, or a
central tendency; an optimal line is drawn horizontally across the chart to gauge the central
tendency (see Page 30 for example).
QUESTION
Six Sigma
Answer:
Relates to the firm’s ability to produce error-free products; uses six standard deviations rather
than three, which translates to 3.4 defects per 1 million units (99.99966% error-free). Uses the
DMAIC (Define, Measure, Analyze, Improve, and Control) process; uses quantitative and
qualitative techniques.
QUESTION
Project Charter
Answer:
Used in the Six Sigma “define” stage to include all aspects of a project to ensure optimal success,
including the project scope, problem statement, time frame, boundaries, and team members.
QUESTION
DMAIC
Answer:
The “define, measure, analyze, improve, and control” process of Six Sigma.
QUESTION
Value Stream Mapping
Answer:
Provides an overview of an entire process.
QUESTION
SIPOC Chart
Answer:
Defines the supplier-input-process-output-customer relationships in a process.
QUESTION
Failure Modes and Effects Analysis (FMEA)
Answer:
Used to identify potential causes of defects, errors, breakdowns, or failures.
QUESTION
Measurement System Analysis
Answer:
Determines the accuracy and repeatability of the measurement methods and devices used to
control variation in the process.
