10. Lean Tools and Approaches
Six Sigma and Lean concepts and methods are
often combined into Lean Six Sigma.
• Both are driven by customer requirements.
• Both try to eliminate waste, reduce costs,
speed things up, and improve quality.
• Both focus on real dollar savings.
• Both rely on a systematic methodology.

33. 99% Accuracy
Practical Meaning of “99% Good”
• 20,000 lost articles of mail per hour
• Unsafe drinking water almost 15 minutes each day
• 5,000 incorrect surgical operations per week
• 2 short or long landings at most major airports each
day
• 200,000 wrong drug prescriptions each year
• No electricity for almost 7 hours each month
99% Is NOT Good Enough Anymore
34. 6 – The Measurement
99.0% = 3.85
99.9996% = 6
Is there really a big difference
between 99.0% & 99.9996%?
35. What’s in a name?
• Sigma is the Greek letter representing the standard
deviation of a population of data.
• Sigma is a measure
of variation
(the data spread)
σ
µ
36. Facts
• All work is a process
• All processes have variation and waste
• Variation causes defects waste causes loss
• Processes can be improved by understanding
the nature of the variation and waste
37. What does variation mean?
20
• Variation means that a 15
process does not produce 10
the same result (the “Y”) 5
every time. 0
-5
• Some variation will exist in
-10
all processes.
• Variation directly affects customer experiences.
Customers do not feel averages!
38. Measuring Process Performance
The pizza delivery example. . .
• Customers want their pizza
delivered fast!
• Guarantee = “30 minutes or less”
• What if we measured performance and found an
average delivery time of 23.5 minutes?
– On-time performance is great, right?
– Our customers must be happy with us, right?
39. How often are we delivering on time?
Answer: Look at
the variation!
30 min. or less
s
0 10 20 x 30 40 50
• Managing by the average doesn’t tell the whole story.
The average and the variation together show what’s
happening.

• Sigma level measures how often we meet (or fail to
meet) the requirement(s) of our customer(s).

57. Process Maps
• Another important set of deliverables of
the Define phase are process
• maps.
• The maps should be based on the actual
state of the process, or "asis“ maps.
• They should not show the desired state at
this point in the project.
58. High Level Process Maps
Develop high level process maps to include next-level subprocess overviews,
identify process linkages and gaps to ensure that the teams are aligned.
Deliverables:
a. Sub Team Processes Mapped to Critical Steps
b. Team Leaders Met and Reviewed & Aligned Maps
59. SIPOC.

67. NEXT MAKE THE
FUNCTIONAL DEPLOYMENT MAP
• The third stage of mapping is
to create a more detailed "as-
is" picture
• The functional deployment
map displays the steps of a
process in sequential order.
• The functional deployment
process map also illustrates
what function performs the
process step.
68. The steps for creating a functional deployment map are:
• Review the top-down chart with the team.
• List each of the process steps in sequential order
in the first column.
• Use the horizontal axis across the top to show the
location/ responsibility or department for each
step performed.
• Depict individuals (by job title/position), specific
locations, or work functions.
• Indicate the steps, activities, and decisions that
make up the process under the associated
functional column.
• Identify the sequential order in which the steps are
actually performed.
• Use arrows to indicate the direction of the process
flow
• Review the final map and correct as necessary.
70. Annotating Process Maps
• After the map is complete, additional information can be added
depending on the project goals.
• For instance, if the goal is to reduce cycle time,the time for each
step may be added.
• If the goal is to reduce defects, yield information may be added. T
• This may help the team identify the areas on which to focus.
• However, this type of information may not be readily available and,
often, after the data are collected in the Measure phase, the maps
are updated
71. Process Understanding
Process Map – should allow people unfamiliar with the process to understand
the interaction of causes during the work-flow. Should outline Value Added
(VA) steps and non-value add (NVA) steps.

73. QUICK WINS
• Criteria for Good Quick Wins
• After the mapping activity is done, the team should then use the
maps to assess if there are some obvious opportunities for Quick
Wins.
• Quick Wins should be changes that are easy, fast, and cheap to
implement, andthat fall within the team's responsibility.
• In addition, the team may want

DIAGRAM (FISH BONE)
Fish Bone Diagram - A tool used to solve quality problems by
brainstorming causes and logically organizing them by branches. Also
called the Cause & Effect diagram and Ishikawa diagram
Provides tool for exploring cause / effect and 5 whys
77. Cause and Effect Matrix
• The Cause and Effect Matrix gives weights to
each y indicating the importance of that y.
• Man Material Money Machine Method
Environment
• Then, each x is rated in terms of its correlation to
each y. Calculations are made based on the
importance and Correlation, and higher scoring
x's are the best candidates for data
collection.
• Rate the degree to which the x affects or is
correlated to each y.
• Use the following scale:
– 0 - no effect or correlation
– 1 - small effect or weak correlation
– 3 - medium effect or medium correlation
– 9 - strong effect or strong correlation.
• This scale ensures that the x data that the team
thinks has the strongest effect on the y will stand
out.
• Multiply each rating by the weight and sum across
the row, putting the result in last column.
• The x's with the highest totals are the ones
that the team should try to collect.
79. FIFTH TOOL :THE PARETO CHART

107. Measure Overview
What is the Measure phase?
The Measure phase defines the defects, establishes improvement
goals, determines that the system of measuring defects is
repeatable and reproducible and gathers data about the process.
Why is the Measure phase important?
The Measure phase ensures that you specifically define the
defects you are going to measure and that your measurement
system is accurate before you begin to actually measure the
process.
107
108. Measure
• The primary purpose of • Deliverables from the
the measurement phase Measure phase include:
is to answer the
questions, • Collected data
• "How are we doing?" and • Selection of what
"How far do we have to measures to use
go?“
• The team needs to • Baseline of the "current
establish a baseline of state“
the current performance
level. • Data collection plan
109. • Develop operational definitions for each CTQ
characteristic
• Figure out how to measure internal processes affecting
each CTQ, KPOV (Key process output variables), KPIV
(Input Vars)
– Y = F(x)
• Figure out what data we need to collect
– Easy to collect correctly
– Interrupt process as little as possible
– Collectors understand why collecting
– “gage study” to determine the validity (repeatability and
reproducibility) of the measurement procedure for each CTQ
• Baseline data
– Collect baseline capabilities for each CTQ
– Determine the process capability for each CTQ

111. WHAT CAN BE MEASURED
• Input Indicators - Measures that • Output Indicators - Focus on the
evaluate the degree to which the end result. Measures that evaluate
inputs to a process (provided by dimensions of the output - may
suppliers) are consistent with what focus on the performance of the
the process needs to efficiently business as well as that
and effectively convert inputs into associated with the delivery of
customer satisfying outputs. products and services to
customers.
• Examples of input indicators
– . # of customer inquires • . Retention rates
– . Type of customer inquires • . Total # done, sold, made, etc.
– . # of orders • . On-time
– . # of positions open • . Complete
– . Accuracy of the analysis
– . Timeliness
112. WHAT ALL CAN BE MEASURED
AS GOOD AND DEFECTS
• Process Indicators - Focus turning opportunities into desired
results. Measures that evaluate the efficiency, effectiveness and
quality of the transformation processes (i.e., the steps and activities
used to convert inputs into customer satisfying outputs.)
• Examples of process metrics include:
– . Availability
– . Time to do something, timeliness
– . # of non-standard request
– . Yield (first time through)
– . # of exceptions (e.g., non standard approvals)
– . Quality level (could also be an output metric)
113. TIME METRICS
• Lean process improvement teams often look at time metrics.
• Takt time - the unit-to-unit pace of production required to meet
customer demand. This is the ideal pace for doing work. At this rate
production and demand are in balance.
• Cycle time - the actual elapsed process time from the completion
of one output unit to completion of the next unit. Cycle time for a
process is the length of time for the longest step within the
process.So if a four step process has three steps of two minutes
each, and one step of five minutes. The cycle time is five minutes.
• Lead Time - the length of time from the beginning point of a process
to the completion of a finished output (calculation varies depending
on scope; it includes: queue, wait and move times).
• Time metrics can also include frequency, degree of impact,
response time,
114. RESULTS OF MEASURE STAGE
• Do the metrics link to the team's improvement goals?
• Do the metrics have a balance of viewpoints (customer, supplier,
process, productivity, quality, etc.)?
• Was a plan developed for collecting the information?
• Was a baseline established?
• Does the data collected look like it will provide the necessary information for analysis
and decision making purposes?
• Are all significant process steps captured?
• Was the data validated for reasonableness by anyone outside of the team?
• Which metrics may be useful in sustaining improvement after implementation of the
changes?
