Business Processes
A business process is an activity or set of activities that can accomplish a specific organizational
goal. Business processes should have purposeful goals, be as specific as possible and have
consistent outcomes.
 Most business processes will produce outputs that are defect free.
 However every business process will produce some
number of outputs that are either considered to have defects or be defective.
 When a part contains a defect or is considered
defective it has deviated from a standard which is tracked in six sigma.
Six Sigma - Overview
 Six Sigma is a disciplined and quantitative approach involving setting up a system
and process for the improvement of defined metrics in manufacturing, service,
or financial processes.
 Its a improvement system for existing process falling below specification and looking
for incremental improvements.
 Six Sigma is a management methodology which allows companies to use data to
eliminate defects in any process.
 Six Sigma is a strategy that gives organizations a structured means to improve
business processes and solve problems.
What does the term mean?
 Six Sigma defined technically refers to achieving a performance level that
is 6 rated, in other words producing no more than 3.4 defects per million
opportunities.
 Sigma  Used to denote variance from a mean
oran average. Literally translated means Standard Deviation.
Six Sigma : History
Bill Smith, Father of Six Sigma
In the early and mid-1980s with Chairman Bob Galvin at the helm, Motorola engineers
decided that the traditional quality levels  measuring defects in thousands of
opportunities  didnt provide enough granularity. Instead, they wanted to measure the
defects per million opportunities. Motorola developed this new standard and created the
methodology and needed cultural change associated with it. Six Sigma helped Motorola
realize powerful bottom-line results in their organization  in fact, they documented more
than $16 Billion in savings as a result of our Six Sigma efforts.
Six Sigma has evolved over time. Its more than just a quality system like TQM or
ISO. Its a way of doing business. As Geoff Tennant describes in his book Six
Sigma: SPC and TQM in Manufacturing and Services: Six Sigma is many things,
and it would perhaps be easier to list all the things that Six Sigma quality is not.
Six Sigma can be seen as: a vision; a philosophy; a symbol; a metric; a goal; a
methodology. We couldnt agree more.
Six Sigma - Benefits
 Increased Business Performance
 Reduced Defects
 Reduced Variation
 Improved use of Resources
 Stable and Consistent Processes
 Meet Customer Demands
 More Market Share and Capital Growth
Six Sigma : Objective(s)
 Skills to predict, prevent and control defects in a
process.
 Skills to understanding of the elements of waste
in a process.
 Skills to achieve sustainable quality
improvement
 Skills to understand tools of process discovery.
 Skills to understand of variation in processes.
 Skills to understand how to reduce variation in
processes and achieve predicted outcomes.
 Skills to identify, measure and analyze process
potential.
Six Sigma : Quality Tools
Mainly 7 Tools that are used for quality improvements in any business process
 Cause and Effect Diagram
 Check Sheet
 Flow Chart
 Histogram
 Pareto Diagram
 Control Chart
 Scatter Diagram
Six Sigma : Tools
Tool Description
Cause-and-effect diagram Identifies many possible causes for an effect or problem and sorts ideas
into useful categories.
Check sheet A structured, prepared form for collecting and analyzing data; a generic
tool that can be adapted for a wide variety of purposes.
Control charts Graphs used to study how a process changes over time. Comparing current
data to historical control limits leads to conclusions about whether the
process variation is consistent (in control) or is unpredictable (out of
control, affected by special causes of variation).
Histogram The most commonly used graph for showing frequency distributions, or how
often each different value in a set of data occurs.
Pareto chart Shows on a bar graph which factors are more significant.
Scatter diagram Graphs pairs of numerical data, one variable on each axis, to look for a
relationship.
Stratification A technique that separates data gathered from a variety of sources so that
patterns can be seen (some lists replace stratification with flowchart
or run chart).
Six Sigma : Measuring a Process via VSM
 In Six Sigma Process is measured via VALUE STREAM Mapping
Verify or define priorities and team
Accept or define charter
Look at the waste
Understand the current state
Shape the future state
Target the ideal state
Reveal Action Plan
Establish a value stream coach
Announce and share
Map everything
Six Sigma : Benefits of VSM
 Shows the entire flow of the value stream as it happens.
 Makes value and non value in a process visible.
 Helps plan improvements/Kaizen events.
 A value stream map shows material and information flows
 Helps us see the flow of activities from customer perspective.
