Six Sigma Overview Six Sigma Overview • A rigorous methodology A rigorous methodology • Originated by Motorola (1986) – A A statistically‐based method to reduce variation in statistically‐based method to reduce variation in electronic manufacturing processes
• Heavily inspired by • Previous quality improvement methodologies • Quality Control Management, CQI, TQM
• Based on the work of quality pioneers q yp • Deming, Juran, Ishikawa, Taquchi and others

Six Sigma Overview Six Sigma Overview • By late 1990s y – 2/3 Fortune 500 companies • Aimed at reducing costs and improving quality
• Today T d – Utilized all over the world • Local governments, prisons, hospitals, the armed forces, banks, g ,p , p , , , manufacturing, etc.
• In recent years – Si Six Sigma often combined with Lean Manufacturing to Sigma often combined ith Lean Man fact ring to yield a methodology called Lean Six Sigma.

Why Six Sigma? Why Six Sigma? • What we were doing wasn’t working well enough! Wh d i ’ ki ll h! – Incremental improvements “not good enough” – Need to /Desire to: Need to /Desire to: • • • •
Focus on customer requirements Base decision on data, not anecdotal information Be Proactive vs. Reactive Establish a culture of ownership vs. culpability – It’s the processes, not the people
• Effect rapid and effective change
– Improvement efforts were fragmented – Large system‐wide processes broken L id b k – Not “holding the gains”
What does Six Sigma offer? What does Six Sigma offer? • Augments traditional quality tools Augments traditional quality tools • Data driven decision‐making • Focuses on customer requirements • A focused/organized approach • Redefines processes for long‐term results • Becomes ingrained in work and thought processes • Relies on evidence‐based solutions • Rapid/effective change
Organizational g Benefits: Competitive edge Service Excellence Empowered staff Empowered staff Leadership Development Quality/Safety Healthcare Costs
Six Sigma Six Sigma • Methodology aimed at • Error reduction • Eliminating variation Eliminating variation
• Goal • Design/improve processes so it is impossible to make an error
• Reliance on performance measurements and statistical analysis statistical analysis

Six Sigma Central Concepts Six Sigma Central Concepts • Critical to Quality (CTQ) Critical to Quality (CTQ) – How the customer judges our products/services Y = The outcome measure of the process X’s = Inputs or variables that affect the Y Defect ‐ Failure to deliver what the customer expects DPMO Defects per million opportunities DPMO – Defects per million opportunities
• • • • • Variation
– The enemy of predictable output and customer satisfaction
• Sigma – An expression of process yield, based on the number of defects per million opportunities (DPMO) defects per million opportunities (DPMO)

Definitions of Six Sigma? Definitions of Six Sigma? • A metric A metric – Greek letter
• A measure of process capability – How capable is our process of meeting our customer’s ’ expectations?
• A rigorous, structured approach to problem‐solving g pp p g – Includes a defined methodology with specific tools and tactics
• A management philosophy – Operational excellence and continuous improvement Operational excellence and continuous improvement Definitions complimentary, not contradictory! p y y
Six Sigma as a Metric • A statistical concept – Represents the variation that exists in a process – Relative to the customer requirements l h
• A process operating at a 6‐ Sigma level – SSo little variation, that the process outcomes are li l i i h h 99.9997% defect free
• Six Sigma = 6 , 6 Sigma, or 6s. Six Sigma = 6 6 Sigma or 6s

Measure of Process Capability Measure of Process Capability • Focus Focus on improving what is important to the on improving what is important to the customer – Critical to Quality (CTQs) Q y( Q ) – This is generally referred to as the “Y” or outcome variable – Examples: wait time, response time, turn around time, % new visits, % med errors, % falls, etc.
• Measure the “Y” against the target – Target = customer expectations or specifications

Measurement System Analysis (MSA) Measurement System Analysis (MSA) • H How accurate is the measurement process? t i th t ? • How much variation is there in the measurement process? • Attempt to minimize controllable factors that could exaggerate the amount of variation in the data Example: I want to measure seconds. The clock only measures minutes Result: The variation of the measurement system is too large to study the current level of process variation the current level of process variation
MSA Examples MSA Examples • Fall Risk/Pressure Ulcer Risk Assessments Fall Risk/Pressure Ulcer Risk Assessments – Performed by all RNs – Patient’s given scores, based on assessment criteria
• Door to Balloon Time – Clocks 1. Reproducibility‐ Does RN # 1 get the same score as RN # 2? 2. Repeatability‐ Does RN # 1 always get the same score when f d ith th faced with the same findings? fi di ? Total measurement system variability should be as small as possible, but always less than 30%.

There are no silver bullets!!! It’s takes plain hard work! Leaders not inherently good sponsors! Challenging to find time, resources, data Difficult to find the “right” staff • Facilitation skills, project management, healthcare knowledge, problem solving, movers/shakers
How will we know when we get there? How will we know when we get there? The following elements will occur on a daily basis: The following elements will occur on a daily basis: – High performing hospital processes – Data driven decisions and problem solving – Focus on processes not people or departments – Recognition of widespread variation and its impacts – Acceptance of rapid change – Enthusiasm about finding “better ways of doing things”
