ANSWERS RATED A+
calls between 3 mins (LSL) and 6 mins (USL)
✔✔Sample of Process Capability - ✔✔Insert slide middle slide from page 7
✔✔How is Six Sigma defined? - ✔✔-As a Philosophy
-As a Set of Tools
-As as Methodology
-As a Metric
✔✔What is DMAIC? - ✔✔Define Measure Analyze, Improve and Control
✔✔In the concept of process capability is a larger or smaller number better? - ✔✔Larger
✔✔What is the definition of Six Sigma Philosophy? - ✔✔Views all work as processes
than can be defined,
measured, analyzed, improved, controlled (DMAIC)
✔✔What is the definition of Six Sigma as a Set of Tools? - ✔✔Six Sigma contains the
qualitative and quantitative
tools to carryout DMAIC activities
✔✔What is the definition of Six Sigma as a Methodology? - ✔✔Six Sigma is a problem-
solving methodology following
the sequence of events set forth in DMAIC
✔✔What is the definition of Six Sigma as a Metric? - ✔✔Six Sigma uses actual process
measures (e.g. Cp) as a
perspective; "tightening" the process is the goal of Six
Sigma from the perspective as a metric
✔✔What is the difference between Six Sigma and Lean? - ✔✔-Six Sigma focuses on
reducing process variation & enhancing process control
-Lean drives out waste (non-value added activities) & promotes work standardization
✔✔If you were following the methodology that lean and six sigma were separate tools,
each useful in their proper time and place, which would you apply first in a process
improvement effort and why? - ✔✔Lean first and then Six Sigma next. Drive out waste
and next reduce process and variation.
, -First, get the process trimmed down to get rid of any activities not needed using lean
techniques.
-Then, work on getting that revised workflow (process) optimized using six sigma tools.
✔✔What is the rationale on using lean techniques prior to six sigma? - ✔✔-You wouldn't
want to spend time improving parts of a process that are a non-value added.
✔✔Does effectiveness relate to lean or six sigma? - ✔✔Lean
✔✔Does Efficiency relate to Lean or six sigma? - ✔✔Six Sigma
✔✔What is Effectiveness? - ✔✔Effectiveness is doing the right things righty
The state of having produced a decided pm pr desired effect
✔✔What is Efficiency? - ✔✔Efficiency is doing things right
A process that operates effectively while consuming minimal resources (such as labor
and time)
✔✔Can Lean and Six Sigma be blended? - ✔✔Yes, Lean Six Sigma. Lean can be used
first to eliminate waste, then apply six sigma to eliminate process variations
✔✔In the example of a process to get signatures on a form has 9 steps and often a
variety of wrong signatures are on the form, how would you apply lean? - ✔✔Reduce to
three steps
✔✔In the example of a process to get signatures on a form has 9 steps and often a
variety of wrong signatures are on the form, how would you apply six sigma? - ✔✔Track
reasons for incorrect signatures and apply DMAIC control technique.
✔✔Tell me about quality pioneer Subir Chowdhury... - ✔✔-Relatively new leader in
quality development
-focuses on management of quality systems
✔✔Tell me about quality pioneer Philip Crosby? - ✔✔-Originated the concept of zero
defects
-14 steps to quality improvement
Key books
-Quality is free
