Six Sigma Simplicity
“85% of the reasons for failure to meet customer requirements are related to deficiencies in systems and processes…rather than the employee. The role of management is to change the process rather than badgering individuals to do better.”- W. Edwards Deming (1900 -1993)

History of Lean Six Sigma
Began in 1979 at Motorola – Art Sundry at a management meeting – “The real problem at Motorola is that our quality stinks”Initiative was designed to help a business anticipate problems, not just react to them (Saved $2.2 billion over 4 years with Six Sigma)Lean began with Ford – then Toyota – emphasis was on improving efficiency by optimizing flow – based on Toyota Production SystemIn the 1980’s it was named “Lean Production” because of the focus on removing wasteIn the late 1990’s Allied Signal and Maytag independently developed curriculum including aspects of Lean and Six SigmaThe goal of combining these programs was to reduce waste and cost while improving quality

Who Has Used Lean Six Sigma?
GE – operating margin improvement of 16.7% in 3 yearsAllied Signal - $2 billion in cost savings in 5 yearsRaytheon - $1 billion annuallyMotorola - $500 million annuallyCaterpillar - revenue grown of 80% in 4 yearsOther examples:Amazon.comBank of AmericaGIECOChaseCSXThousands more…

Common Objections to Lean Six Sigma
Just another flavor of the month – here today, gone tomorrow Too costly to implementNot effective – have heard horror storiesIt can be done without a formal program or structureIt’s another way to reduce headcountIt’s only theorySix Sigma SimplicitySlide6
Top Ten Ways Lean Six Sigma Programs Fail
Make sure senior management is only lightly involvedChoose the least-experienced employees to become ‘Black Belts’Select a Lean Six Sigma training company based on cost, not credentials (in other words, skimp on training)Select projects that are not aligned with your core business strategySelect very low-value, low-impact projectsAssign projects then forget about them
Provide everyone in the company with Six Sigma awareness training, then walk away
Think of Lean Six Sigma as a collection of projects rather than business transformation efforts
Expect results in short periods of time – patience is a virtue
Only expect operational improvements – customers may or may not ever feel the improvements
Six Sigma SimplicitySlide7
Lean concepts came from the Toyota Production System, translated through teachings of Ohno and Shingo
The goal of Lean is to:Eliminate waste (muda) such that you are only doing value added workValue added is defined as:Customer recognizes the value (willing to pay for it)Changes the product in a desired mannerProcesses that are done right the first time
What is
Lean?
Six Sigma SimplicitySlide8
Sigma is a letter in the Greek Alphabet
Sigma is a symbol which shows the degree of variation in a process (standard deviation)The goal of a Six Sigma capable process is to:Minimize variation Center the processThe degree of acceptable variation in a process depends on knowing the target.
Do you know where your target is?

Six Sigma

How close are you to meeting your target?

Why Combine Lean and Six
Sigma?Simple:Common SenseReduction of wasteReduction of variationReduced operating costsComplex:Vision & strategic approachMethodology that aligns improvements to strategic objectives & utilizes aggressive goal-setting to drive real bottom-line financial improvementTool for: customer focus,
continuous
improvement, p

What Lean Six Sigma Is / Isn’t
What it isn’tA here today/ gone tomorrow approachThe only way to solve a problemOnly applicable in manufacturing industryWhat it isA data-driven methodology focused on bottom-line resultsA methodology focused on driving out waste and variation to improve efficiencyCulture focus on optimizationStructured approach to what we’re already doingSix Sigma SimplicitySlide11
It’s About Changing Mentality / Mindset
Traditional way of thinkingProblem = Trial and Error SolutionThis way can be painful, and is not always based on fact, leading to unforeseen consequencesNo view of upstream or downstream impactsLean Six Sigma way of thinkingPractical Problem translated to a statistical problem, which is solved by a statistical solution, and then translated to a practical solutionData-driven solutions that have long-lasting and meaningful impact to problemsSix Sigma SimplicitySlide12

Thinking (Stevedoring)Reduce vessel start times from 24 minutes to 15 minutesPractical ProblemStatistical Problem

Practical Solution
Vessel Start times are slower than expected
The assignment of the first move is statistically significant to vessel start times

Why now?
Burning PlatformThe slow-moving economy is keeping volumes lowIn some regions, market share is shrinking compared to our competitionMarket competition is driving down ratesIncreased pressure from union’s are driving up labor costsCustomer wants things performed fasterSix Sigma SimplicitySlide17
Why we are doing this…
Reduce daily firefighting, increase in strategic-thinkingImprove profitability of business unit through more targeted projectsProvide management tools that can be applied at all levels of the businessCreate a continuous improvement business cultureIdentify a baseline for future improvementsSix Sigma SimplicitySlide18

Our Common Enemy

Statistical Measures of Distribution
Measures of the Center of DataMean: Arithmetic average of a set of valuesMedian: Reflects the 50% rank - the center number after a set of numbers has been sortedMeasures of the Spread of DataRange: the distance between the extreme values of a data set (Highest - Lowest)
Variance
( ):
the Average Squared Deviation of each data point from the Mean
Standard Deviation ( ):
the Square Root of the Variance
Six Sigma SimplicitySlide23
Distribution Shape: Normal
The Normal Distribution is a distribution which has certain consistent propertiesThese properties are very useful in our understanding of the characteristics of the underlying system from which the data were obtainedMany natural phenomena and most processes can be adequately represented by a normal distributionSix Sigma SimplicitySlide24
The Normal Distribution
Property 1: A normal distribution can be described completely by knowing only the : mean and standard deviation
Distribution 1
Distribution 2
Distribution 3
What is the difference between these normal distributions?

Waste
Goal - Eliminate downtime (waste) such that you are only doing value added workThe common types of waste:Defects - incorrect data entry, inspectionOver production - preparing extra reports, reports not acted upon, multiple copies in data storageWaiting - processing monthly not as the work comes in (i. e. closings, billings, collections)Non-utilized resourcesTransportation - extra steps in the process, distance traveled (equip.)

nventory - transactions not processed
M
otion - extra steps, travel from office to office / desk to desk, extra data entry...

Processing – redundant work, multiple sign-offs, multiple inspections
Six Sigma SimplicitySlide34
Sources Of Waste
Layout (distance)Long set-up timesIncapable processesPoor maintenancePoor work methodsLack of trainingLack of adherencePoor supervisory skillsIneffective schedulingInconsistent performance measuresDies-Functional organization Excessive controls
No back-up/cross-training
Unbalanced workload
No decision rules
No visual control
Lack of workplace organization
Supplier/Partner quality
Inconsistent supply of detail information
Over-engineeringInspection
The longer waste occurs, the more accepting your become!

Waste in the Form of Rework
Waste Causes A "Hidden Factory"Increased Cost & Lost Capacity
Each defect must be detected, repaired and placed back in the process
Each defect costs time and money

Measure Phase
The Measure Phase is about understanding the current state and collecting data to establish a baselineKey Process Input Variables (KPIV’s) and Key Process Output Variables (KPOV’s) that have a heavy influence the process or are the result of the process In this phase, consideration is taken into how accurate and reliable the measurement system that we use isMeasurement system could potentially be the cause of the problemSix Sigma SimplicitySlide67
