Waiting Delays, periods of inactivity, bottlenecks, or patient wait time.
Non-Utilized Potential Failure to fully utilize human potential (time and talents of people).
Transportation Unnecessary movement of supplies, equipment, or people.
Inventory Excess inventory/supplies, batch processing, queues, or backlogs of work.
MotionExtra steps taken by employees because of inefficient layout, searching, hunting and gathering.
Excess Processing Excess activity and processing steps caused by poor process design.

Flow
Value
• Flow is the continuous movement of
people, materials and supplies through a
process.
• Flow ensures that patients have what they
need exactly when they need it.
– No delays or waiting
– One piece flow (instead of batching)
– Well organized supplies and work space
– Alignment of work volume and resources
– Replenishment of only what is neededReferences: Joosten T, Bongers I, Jansen R. Application of Lean Thinking to Health Care: Issues and Observations. Int J Qual Health Care 2009; Volume 21, Number 5: pp. 341-347. Source URL: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2742394/

Establish Pull
Perfection
Waste
Pull
Value
• Pull is the timely transition of work from
one process step to the next.
• Pull means performing work as it is
requested or needed by a step in the value
stream so that demand triggers action.
• When a downstream process is ready for
more supplies, patients, etc., a signal is
made to pull more into the process “just in
time” (JIT).

Specify Value
• Value is defined by the patient.
• Value may be tangible or intangible.
• Every process should be designed
to deliver what the patient values
and would be willing to pay for in the
service/care that is being provided.

• In a value stream view of the patient journey:
– The patient is an active participant in their
own care.
– The patient makes informed choices
regarding their healthcare options and goals.
– In partnership with the patient, the care team
helps the patient safely navigate through their
journey to achieve their goals.

Silos
• Instead of working together as a value stream we often
function as silos that work in isolation from each other.

Evelyn A. Catt, 2015
Risk Mitigation
• The potential risk of silos in the value stream must
be mitigated, especially during patient hand-offs.

Safe Hand-offs
• Implementing tools such as SBAR (situation,
background, assessment, recommendation) helps
ensure consistent hand-off communications are
completed.
• Value added = increased patient safety.

Evidence-Based Standard Work
• Standard work is the best known way of
performing a process today.
• Standard work is based on creative
problem solving and continuous
improvement.
• Standard work evolves over time as new
evidence-based practices are identified
and implemented.

Continuous Improvement
• Lean is a journey of continuous improvement in
pursuit of perfection using:
– Evidence based practices/standard work
– Continuous Improvement (PDSA cycle)
– Monitoring quality & performance metrics
– Rapid Improvement Events (RIEs), Kaizen Events
– Value Stream Mapping & Value Analysis
– Lean 5-S (sort, store, shine, standardize, sustain,+ safety)
– Visual Management (color coding, visual cues)

Summary
• Lean is focused on the constant pursuit of
perfection by eliminating waste and non-
value added activities to improve the flow of
value to the patient.
• Value is defined by the patient.
• Every process in the value stream should be
designed to deliver what the patient values
in the service/care that is being provided.

Systems Thinking
37.
Evelyn A. Catt, 2015
Origin of Systems Thinking
“A fault in the interpretation of observations, seen everywhere, is to suppose
that every event is attributable to someone (usually the one closest at hand),
or is related to some special event.
The fact is that most troubles……. lie in the system and not the people”.
Dr. W. Edwards Deming, The New Economics

Evelyn A. Catt, 2015
A3 Thinking
• A3 Thinking is a structured, collaborative problem solving process.
• The A3 process uses the PDSA (plan-do-study-act) model as the
foundation of an iterative cycle of continuous improvement.
• This cycle promotes “systems thinking” and the development of
people as “problem solvers”.
39.
Evelyn A. Catt, 2015
Plan – Do – Study – Act (PDSA)
• The PDSA “Model for Improvement” serves as the foundation of A3
Thinking and the pursuit of continuous improvement.
• The PDSA model guides rapid improvement cycles using small tests
of change driven by empowered employees.
• The PDSA cycle starts by asking three questions:
– What are we trying to accomplish?

A3 Thinking
• Why is it called “A3” Thinking?
• The term “A3” refers to the 11x17 size of paper used for the A3 report.
• The A3 report format is used for simplicity, consistency, and also serves
as a rapid communication tool to promote organizational learning.

Evelyn A. Catt, 2015
Origin of Lean
• Lean principles are based on a management philosophy derived
from the Toyota Production System (TPS).
• TPS is focused on the identification and steady elimination of
waste to preserve value with less work.
• This is achieved by getting the right things to the right place at the
right time in the right quantity to achieve perfect work flow, while
minimizing waste.
• When applied in the daily workplace, “Lean thinking” is used to
continually improve all functions by people at all levels in the
organization.

Lean Focus
Lean is focused on the
constant pursuit of perfection
by eliminating waste and
non-value added activities to
improve the flow of value to the customer.
48.
Evelyn A. Catt, 2015
Lean Thinking
“Lean Thinking”
creates a culture and practices
that continually improve
all functions by all people
at all levels in the organization.
49.
Evelyn A. Catt, 2015
Lean Rules
RULE 1: Clearly specify all activities.
Mindful standardization of work.
• Content: What is being done?
• Sequence: In what order?
• Timing: How long should it take?
• Outcomes: What clearly defined
measurable results are expected?
RULE 3: Clearly define all pathways.
Organize for uninterrupted flow.
• Simple (with as few steps and people
as possible).
• Direct steps to deliver the requested
product or service.
Reference: Spear, S. and Brown, H.K. Decoding the DNA of the Toyota Production System, Harvard Business Review, 1999
Source URL: http://www.systems2win.com/solutions/5s.htm
RULE 2: Clearly define all connections to
every customer and supplier.
No ambiguity.
• Direct (no intermediary between)
• Yes or No answers (no maybes)
RULE 4: Continuously Improve.
Develop leaders who can apply the
scientific method to improve anything.
• Direct response to any problem that arises.
• By those doing the work - as close to the
problem as possible.
• If feasible, start as an experiment.
• Supported by a coach.

Lean
Key Concepts
52.
Evelyn A. Catt, 2015
Key Concepts
• All work is a process and even the smallest change can
impact the entire organization.
• Every process should be designed with the patient in
mind, to deliver what the patient values in the process.
• Lean organizations are continually improving and
looking for new opportunities to:
– Eliminate waste
– Increase value to the patient
– Achieve efficient work flow

Evelyn A. Catt, 2015
Value Added Process
A value-added process:
• Creates value for the patient/customer.
• Produces a good result every time.
• Does not cause delays.
• Is satisfying:
– for people to perform
– for managers to manage
– for patients to experience

Waste
• Waste is any activity that consumes time, resources,
or space but does not add value to the product or
service in the eyes of the patient.
• And waste consumes resources!

The Cost of Quality
56.
• The Cost of Quality is the sum of four cumulative types of costs:
– Appraisal, Detection, Internal Failure, External Failure
• The Cost of Poor Quality is the cost associated with producing defects,
which includes internal failure costs and external failure costs.

Six Sigma Principles
57.
Evelyn A. Catt, 2015
Origin of Six Sigma
• Six Sigma was originally developed by Motorola in 1986.
• Motorola set a goal of "six sigma" (99.99966% perfect) for all of its
manufacturing operations, and this goal became a byword for the
methods used to achieve it.
• Six Sigma seeks to improve the quality of process outputs by
identifying and removing the causes of defects (errors) and
minimizing variation.
• Reducing variation in a process is the key to reducing errors and
waste, which increases reliability.
• Increased reliability results in safe, high quality care.

Understanding Variation
63.
Lean Six Sigma uses data:
• To understand the sources of variation
• To target factors that have the most influence on performance
• To design evidence-based improvements
• To monitor and sustain results over time
• To conduct proactive analysis of potential failure modes to:
o Reduce risks
o Reduce errors
o Increase safety
Evelyn A. Catt, 2015
Variation & Reliability
• Variation: A measure of change or difference.
• Reliability: Consistently giving the same result.
64.
Evelyn A. Catt, 2015
Types of Variation
• Common Cause Variation: Natural variation within a process
(expected or acceptable variation).
• Special Cause Variation: Unpredictable or extreme variation
(unexpected or unacceptable variation).
65.
Evelyn A. Catt, 2015
Variation in Healthcare Processes
Examples of variation in healthcare processes:
• Quality
– Accuracy of labeling blood tubes
– Completeness of pre-op testing for surgery patients
– High readmission rates for patients with diabetes
• Timeliness
– Turnaround time for test results
– Length of time to get a clinic appointment
– Waiting time in the Emergency Department
• Cost
– Variation in the cost of treating patients with the same diagnosis
– Differences in the cost of supplies from multiple vendors
– Fluctuations in employee turnover rates and the associated costs
66.
Evelyn A. Catt, 2015
Concept of a Function
67.
• Six Sigma changes the problem solving approach from trial and
error to Y = f (x).
• A process is described by identifying the measurable output (Y)
and all known inputs (x).
• The Six Sigma roadmap and tools are used to analyze the
relationship between the measurable output (Y) and the process
inputs (x).
Y = f (x)
The value of Y is a function of the value of x
Y (measurable output) = function of x (process inputs)
Y (measurable output) is sometimes referred to as the “Big Y”
Evelyn A. Catt, 2015
Concept of a Function Example
68.
Y (% of surgery on-time starts) = function of (x1, x2, x3, x4, x5,…….)
x1 = Patient shows up on time
x2 = Admitting office registers patient quickly
x3 = History and physical form (H&P) form received
x4 = Signed, current consent form received
x5 = Required professionals present (RN, surgeon,
anesthesiologist, etc.)
Evelyn A. Catt, 2015
Reducing Variation in Healthcare
To reduce variation in healthcare processes:
• Identify the measurable output (Y) of the process.
• Identify the inputs (x’s) of the process.
• Use LEAN Six Sigma tools to identify the few critical inputs that have
the greatest influence on the output.
• Identify and correct the defects, errors, and variation associated with
these critical inputs. All possible inputs (x’s)

Continuous Improvements
71.
Evelyn A. Catt, 2015
Kaizen – Continuous Improvements
• Kaizen is Japanese for "improvement" or "change for the better“. It refers to a
culture and practices that focus on continuous process improvements.
• When applied in the daily workplace, Kaizen refers to activities that continually
improve all functions by people at all levels in the organization.
• Individual Kaizen improvements can be implemented quickly by one person.
• A Kaizen Event is an intense, rapid improvement event (RIE) with a team that
is focused on a specific process with a well defined scope.

Evelyn A. Catt, 2015
What is Lean 5-S?
• 5-S is a workplace organization tool used to eliminate waste and improve flow
– Eliminates the need for searching
– Reduces probability of error
– Increases quality
– Improves productivity
– Expedites response time
– Improves staff morale
– Enhances professional image of an area
– Increases efficiency of the supply replenishment process by using visual cues such as a Kanban system
• Kanban aligns inventory and consumption levels; a signal is sent to
deliver additional inventory when current supplies are consumed.

Lean 5-S Benefits
• Pride in the workplace and supports team development.
• Sorting means removing unnecessary items that congest the work
area.
• Clean equipment allows everyone to notice problems.
• Sorting retains only the needed items. This allows for a smaller work
area resulting in reduced effort (walking, reaching, etc.) to do the
work.
• Reduced changeover times result from being organized and
minimizing search time.
• Items have a definitive home location that is labeled and easily found.
90.
Evelyn A. Catt, 2015
Keys To Lean 5-S Success
• Get everyone involved.
• Integrate 5-S principles into daily work requirements.
• Communicate need for 5-S, roles of all participants, how it is
implemented.
• Be consistent in following 5-S principles in all areas.
• Periodic senior management involvement is absolutely required.
• Follow through and finish what is started, 5-S takes effort and
persistence.
• Link 5-S activities with all other improvement initiatives.
• Commitment to the process, a few individuals cannot undermine the
efforts of the entire team.

• The goal of standard work is to
develop the most reliable methods
to consistently achieve the best
outcomes for each process.
• This is accomplished by defining
the best known way to perform the
process today.

Core Process Map
• A Core Process Map helps an organization to:
– Promote an understanding of your facility as a system rather than “silos”.
– Learn to understand work as inter-related processes within a system.
– Prioritize projects by identifying the “pain points” across the system that have
the greatest impact on organizational performance.
– Identify key performance measures related to each area’s primary function.

X-Y Chart
• The X-Y Chart helps to identify and prioritize the relationship between multiple
inputs and the resulting outcomes. All process outcomes (Y’s) are achieved
based on the interaction of multiple inputs (X’s), which is often referred to as a
“cause and effect” relationship. Therefore, the X-Y Chart is also known as a
C&E Matrix. The most traditional use of an X-Y Chart is to help narrow down a
large number of inputs (X’s) to a manageable list for further evaluation. Steps:
– Identify & rank customer “critical to quality” (CTQ) requirements across the top of the matrix.
– List all of the inputs to the process down the left side of the matrix.
– Rank the impact of each input on each CTQ requirement (1 = weak, 3 = moderate, 9 = strong) to
determine the correlation between each input and CTQ.
– Cross multiply the input ranking with the CTQ value then add across each line for a total score.
– Sort the total scores from highest to lowest to identify the inputs with the greatest impact.
– Select a breaking point for items with scores that are too low to warrant further investigation.

Customer Requirements
119.
Evelyn A. Catt, 2015
Customer Requirements
• Customer requirements refers to the qualities and features of products
and services that are needed to achieve customer satisfaction.
• It’s important to obtain direct “Voice of the Customer/Stakeholder”
input from patients, physicians, staff, and visitors to define customer
requirements and determine if the current process meets their needs.
• Several methods can be used to obtain the “Voice of the Customer”:
– Conduct interviews
– Establish a focus group
– Develop a questionnaire
– Conduct research
Reference: Six Sigma, Kano Model: Source URL: http://www.six-sigma-material.com/Kano.html120.
Evelyn A. Catt, 2015
First: Go to “Gemba”
• Gemba in Japanese means “the actual place” or “the real place”.
• Go to “Gemba” to observe the current process in action.
• Talk to the people who actually perform the process.
• Identify gaps between the current process and customer defined
requirements and develop a strategy to address unmet needs.
• Identify opportunities to eliminate waste and improve flow.
Reference: Quality Improvement Tools & Tips, Carol Birk, M.S., R.Ph., Purdue University 121.
Evelyn A. Catt, 2015
“Gemba” is Everywhere!
• Gemba is every location where work is being done!
– Administrative Offices
– Clinical Areas
– Non-clinical Areas
– Environmental Services
– Facilities
– Financial Counseling
– Food Services
– Health Information Services
– Human Resources
– I.T. Systems
– Marketing
– Patient Billing
– Payroll
– Quality & Risk Management
– Security
– Supply Chain Management
– Other Areas………………..122.
Evelyn A. Catt, 2015
Foundation for Success
• Observe the work in action.
• Honor everyone’s contribution.
• Establish relationships based on trust and transparency.
• Design every process with the patient in mind!
123.
Evelyn A. Catt, 2015
Brainstorming
• Brainstorming is used to rapidly
generate ideas from multiple people
simultaneously regarding customer
requirements:
– Write the name of your process on a
flipchart or whiteboard.
– Without discussion, each person works
independently and writes their ideas on
sticky notes regarding potential
customer requirements.
– Each person posts their sticky notes on
a flipchart or white board.
– No comments, censoring, or criticism is
allowed during this process.

Affinity Diagram
Diagram Source: http://www.six-sigma-material.com/images/AffinityDiagram.GIF
• An Affinity Diagram is a group decision-making technique designed to sort a large
number of ideas/concepts/opinions into naturally related groups. Affinity
Diagrams are often used to sort customer requirements into logical categories.
125.
Nominal Voting Technique
Each person is then given a
limited number of colored dots
(usually 5-8) and votes by
placing a dot on the items they
consider the highest priority.
Evelyn A. Catt, 2015
Reflections
• What type of leadership style will be required to create a culture that
honors everyone’s contribution?
• Are relationships based on trust and transparency in your current work
environment?
• How will the practice of “going to Gemba” be received by the areas
being observed?
126.
Evelyn A. Catt, 2015
Voice of the Customer/Stakeholder
Goals
• Obtain direct “Voice of the Customer/Stakeholder” feedback from
patients, physicians, staff, and visitors about the current process.
• Identify gaps between the current process and customer defined
requirements. Develop strategies to address any unmet needs.
Questions To Ask (SWOT Analysis)
• What do you like about our services? (Strengths)
• What do you think needs improvement? (Weaknesses)
• What Opportunities do you feel we could take advantage of?
• What could potentially Threaten our success?

Characteristics of Products & Services
• The characteristics of products and services can be defined as:
– Dissatisfying: annoying features - avoided characteristics
– Mandatory expectations: basics - must have characteristics
– Customer needs: reasonable expectations - performing features
– Delighters: surprise - innovators - unexpected features
• To find out which characteristics deliver on which level of
satisfaction it is necessary to develop a questionnaire, interview,
or focus group; or conduct research to find the customer defined
characteristics and the associated level of satisfaction.
Reference: Six Sigma, Kano Model: Source URL: http://www.six-sigma-material.com/Kano.html
133.
Evelyn A. Catt, 2015
• The Kano Model is used to visually depict the customer defined
characteristics (for products and services) versus the level of satisfaction
each characteristic delivers.
• The Kano Model can be used to organize and prioritize activities to design
and/or improve products and services to meet or exceed customer
requirements.

DISSATISFIEDCUSTOMERS
Achievement Axis
Satisfaction AxisNot necessarily expressed
Happy surprises, unexpected features!
Expressed needs
Strong source of satisfaction.
Usually unexpressed
“Must haves”, basic requirements.
Evelyn A. Catt, 2015
Must Haves ( “Basic Needs”)
These basic requirements are not always expressed but they are obvious to the
customer and must be met. These requirements are not a source of satisfaction
but can cause major disappointment if they are not met.
Examples: brakes of a car; bed in a hotel room.
Performance Needs (”Linear”)
The need is expressed and customer satisfaction is proportional to the level of
performance (and quality) of what is implemented. It is a strong source of
customer satisfaction and a priority for development. Customer feedback on these
products and services is crucial.
Delighters ( “Exciters “)
These requirements are not necessarily expressed. Sometimes they’re unconscious.
This is the happy surprise that can make a difference, and an important source of
satisfaction. If not there, no dissatisfaction, no frustration: they’re not expected.
Exciters are the keys to innovation!

Flow
149.
Evelyn A. Catt, 2015
Flow
• Flow is the continuous movement of people, materials and supplies
through a process.
• Flow ensures that patients have what they need exactly when they
need it.
– No delays or waiting
– One piece flow (instead of batching)
– Well organized supplies and work space
– Alignment of work volume and resources to meet customer demand
• Takt time = available working time / customer demand
• Takt time is often called “the heartbeat” of a Lean organization
– Allows replenishment of only what is needed

Evelyn A. Catt, 2015
Root Cause Analysis (5 Whys)
• A Root Cause Analysis is a standardized method used to identify the real
cause of a problem, rather than the superficial, easily identified cause.
• To use this technique, ask “why” 5 times to drill down to the underlying root
cause of the issue (next slide).
• Brainstorm solutions and corrective actions.
• Discuss the analysis and pros & cons of each potential solution.
• Additional questions to consider after you complete the “5 whys” exercise.
– Why wasn’t the error prevented by our current system?
– Why do our tools, rules, or procedures allow the problem to occur?
– Why didn’t our system immediately catch the problem?
– Why wasn’t it obvious how to fix the problem?

Mistake Proofing
• Mistake Proofing is about adding controls to prevent errors,
reduce their severity, and detect them if they can occur. These
mistake proofing mechanisms are called “Poka Yokes”.
• Replacing inspection and correction with true quality is known as
“Quality at the Source”.
GOOD: Detect errors/defects before proceeding to the next step.
BETTER: Detect errors/defects during the actual process.
BEST: Prevent errors/defects from occurring at all.

Evelyn A. Catt, 2015
Project Selection & Prioritization
• Identify and prioritize projects that:
– Are aligned with the organization’s strategic goals.
– Have the most significant enterprise-wide benefits.
– Provide the greatest value to patients.
• Ensure that projects have a manageable scope
• Identify project metrics
– Define key performance metrics.
– Measure current “initial state” performance for each process being studied.
– Establish well defined “target state” process improvement goals and return
on investment (ROI) goals. The percent Return on Investment (ROI) =
Gain from Investment – Cost of Investment x 100Cost of Investment

• The problem statement is the reason for action. It is a basic
description of the process to be worked on and the background of
the current problem or opportunity. Examples:
– Only 20% of surgery patients are seen in the pre-admission
testing area, which results in delays on the day of surgery due to
additional testing that needs to be performed before the patient
goes to the O.R.
– The Emergency Department average length of stay exceeds
benchmark standards and the Left Without Being Seen rate is
escalating due to the long waiting times in the E.D.
– 5% of laboratory specimens are submitted without a label, which
results in additional work to redraw the specimens, unnecessary
discomfort to patients, and delayed test results.

Defines the project goal: “improve
(primary metric) from (baseline) to
(target) by (date)”
Measure baseline “initial state” and
improvement level when the project ends
Secondary MetricCaptures, validates and tracks
welcome side effects of the project
Measure baseline and impacts of project
after improvements. Monitor during and
after project if linked to financial metric.
Financial Metric
Links progress in the primary and
secondary metrics to financial
advantage. Most often this metric is
tailor-made for the specific project
Evaluate at project milestones and at
regular intervals for one year after the
project ends to calculate project ROI.
Consequential
Metric
Captures, validates and tracks
unwelcome side effects of the project
Collect data before, during and after the
project to confirm that no collateral
damage was caused by the project.

• How will we know a change is an improvement?
– Define key performance metrics for each process being evaluated.
– Indicate which strategic area is aligned with each metric (quality/safety,
finance/growth, service, people, education, etc.)
– Select one primary metric for the project team to focus on for each
improvement project.
o Use the primary metric to formulate the main project goal.
– Brainstorm for possible secondary and consequential metrics.
o Construct a financial metric based on the primary & secondary metrics.
– Confirm that all metrics meet the criteria to create a data collection plan.
o Measure current performance = “initial state”
o Establish well defined process improvement goals = “target state”

Stakeholder Analysis• Stakeholders are persons or groups with an interest in a project. Their
interest may be based on the impact a project may have on their area’s
processes, or because they have to supply resources to support the project.
• A rule of thumb for identifying key stakeholders is to question whose
support or lack of it may significantly influence the success of the project.
• Stakeholder participation:
– Gives people the opportunity to provide input regarding how projects or policies
may affect their areas
– Generates a sense of ownership if initiated early in the development of the
project
– Provides opportunities for learning and gaining a new perspective on the process
– Enhances responsibility and accountability for achieving project milestones
– Can reduce or reverse the threats to solutions that are developed by the team
– Is essential for sustaining improvements that are implemented during the project
198.
Evelyn A. Catt, 2015
Force Field Analysis• A Force Field Analysis can be used to depict the driving/helping forces that
support movement toward a goal, and the restraining/hindering forces that are
blocking movement toward a goal. This tool is helpful in evaluating key
stakeholders and their interests (positive or negative) in the project.

Data Collection Plan
• Step 1: Define clear goals and objectives for collecting the data.
• Step 2: Clarify operational definitions (examples: procedure starting point,
procedure ending point, time segments during the procedure).
• Step 3: Develop methods to ensure accurate measurements (examples:
synchronized clocks, calibrated instruments, ranking scales, codes for
responses, abbreviations, naming conventions).
• Step 4: Collect data using a standardized format and unique identifier for
each observation (survey, questionnaire, incident report, etc.).
• Step 5: Compile and enter data into a secure electronic database using pre-
defined codes for responses, ranking scales, etc. (immediate entry into an
electronic database is ideal, but not always possible).

Check Sheet
• The Check Sheet is a simple document that is used for collecting data in real-
time at the location where the data is generated “in the Gemba”.
• The document is typically a simple form that is designed for the quick, easy, and
efficient recording of quantitative or qualitative information.
• 5 Basic types of Check Sheets:
― Classification (defect/error or failure mode, classified by category)
― Location (physical location of a trait indicated on a picture of a part or item)
― Frequency (the presence or absence of a trait or combination of traits)
― Measurement Scale (measures indicated on a scale divided into intervals)
― Check List (items to be performed for a task are listed in sequence)
Reference: http://en.wikipedia.org/wiki/Check_sheet
206.

209.
Evelyn A. Catt, 2015
Measurement Checklist
“Initial state” measurements should include the following steps:
Identify key process or outcome measures
Obtain agreement from key stakeholders on key measures
Confirm the operational definition of each key measure
Conduct a Measurement System Analysis to validate measurement accuracy
Create and implement a data collection plan
Calculate high level performance metrics and compare to benchmarks
Identify measures that require additional data or drill-down
Display process variation data using appropriate charts and graphs
Identify high frequency and high impact errors (defects) and variation
Communicate findings to key stakeholders
210.
Evelyn A. Catt, 2015
Measurement Systems
• “If measurements are used to guide decisions, then it follows logically
that the more error there is in the measurements, the more error there
will be in the decisions based on those measurements.”
Errors in measurements = Errors in decisions
Reference: Measurement Systems http://www.moresteam.com/toolbox/t403.cfm
Bad Data = Bad Decisions
Garbage In Garbage Out
211.
Evelyn A. Catt, 2015
Primary & Secondary Data
• Primary Data
– Primary data is original data that has been collected for the first
time for a specific study.
• Secondary Data
– Secondary data is data that was previously collected for another
purpose.
• Statistical Analysis
– When you perform statistical analysis on primary data then the
results become known as secondary data.
Reference: http://en.wikibooks.org/wiki/Statistics/Different_Types_of_Data/PS
212.
Evelyn A. Catt, 2015
Data Integrity
• In order to assess data integrity, the following questions should be
answered:
– Where did the data come from?
– Who has been accessing or manipulating the data?
– Has the data been edited or modified in any way?
– Is there a unique identifier for each entry?
– Are the naming conventions, codes, etc. consistent?
– Are the scoring and ranking tools consistent and valid?
– Has the accuracy of the measurement process been validated?
– Who developed the benchmarking standards?
213.
Evelyn A. Catt, 2015
Data Audits & Validation
• Data must be validated to ensure that it is accurate and to identify
and confirm or remove data that may be suspect.
• Tools for the data audit and validation include (but are not limited to):
– Manual Review
– Frequency Plot (histogram)
– Evaluation of Outliers & Standard Deviations
– Control Charts & Pareto Charts
– Drilling Down by Subpopulations
– Measurement System Analysis (MSA) to validate measurement accuracy
– Common Sense! Does the data appear reasonable?
214.
Evelyn A. Catt, 2015
Sampling Bias
• Bias can occur in multiple ways, resulting in a sample that does not
represent the attributes of the population being studied. Care
should be taken to avoid or mitigate these types of bias:
─ Over coverage: Inclusion of data from outside the population.
─ Under coverage: Some members of the population are not
adequately represented in the sample.
─ Non-response bias: Individuals chosen for the sample may be
unwilling or unable to participate in the study.
─ Measurement systems: Variation in the measurement process
or tools.
─ Processing errors: Mistakes in coding or entering data.
Reference: http://stattrek.com/AP-Statistics-2/Data-Collection-Methods.aspx
215.
Evelyn A. Catt, 2015
Tips to Avoid Data Disaster
• Save a copy of the original database before you make any changes
so you can restore it, if necessary.
• Assign a unique identifier to each observation to:
– Audit for duplicates
– Link de-identified data back to source documents
– Sort data back to the original state
• Limit access to the database, to keep the data secure and avoid the
potential for data corruption or file deletion.
• Use version control methods, such as adding a date to the file name
and initials of the person updating the file.
216.
Evelyn A. Catt, 2015217.
Measurement System Analysis (MSA)
• A measurement system analysis (MSA) is used to identify the components of variation
that exist in a measurement system. It is designed to test the measurements used to
collect data for a Lean Six Sigma project to ensure the accuracy of the data.
• Total observed variation is made up of two parts: the actual variation that exists in an
item or process and the variation that is created by the measurement system itself.
• An ANOVA Gauge R&R (repeatability & reproducibility) test is used to determine the
variability that comes from the measurement system and compares it to the total
observed variation to determine what portion of the variation can be attributed to the
measurement system itself. There are two essential components of a Gauge R&R test:
– Repeatability: The variation in repeat measurements taken by one person or
instrument on the same item and under the same conditions.
– Reproducibility: The variation in measurements that occurs when different
people measure the same item.
• A Gauge R&R value of < 0.1 reflects a good measurement system; 0.1 to < 0.3 is
considered marginal; and > 0.3 is an unacceptable measurement system.

• Quantitative = Quantity
– Deals with numbers.
– Data can be measured and is continuous.
– Length, cost, weight, height.
– Not all numbers are continuous and measurable
(ex: social security number).

• Religion
• Sports
ORDINAL
The categories can be ordered.
• Small, medium, large
• Strongly agree, agree, neutral,
disagree, strongly disagree
• May not know which value is best
• Distance between categories

225.
Evelyn A. Catt, 2015
Interval Data
• Intervals = equally spaced
– Numeric values
– Increments are known, consistent and measurable
– No absolute zero (time, Celsius thermometer)
– Cannot calculate ratios
226.

Parametric and Non-Parametric Data
Source URL: http://www.six-sigma-material.com/images/DataMeasurements.GIF
Non-parametric:
This type of data
can be analyzed
without the mean
(average), standard
deviation, or other
related parameters.
Parametric:
The analysis of this
type of data is based
on assumptions about
probability distributions
using the mean
(average) and
standard deviation.
227.
Evelyn A. Catt, 2015
Measuring Data Consistency
• A simple way of measuring the level of consistency in a data set is by
calculating the Minimum, Maximum, and Range.
Reference: Measures of Central Tendency http://regentsprep.org/REgents/math/ALGEBRA/AD2/measure.htm
Minimum: The smallest value in a data set.
Maximum: The largest value in a data set.
Range:The difference between the Maximum and the
Minimum.
228.
Evelyn A. Catt, 2015
Measures of Central Tendency
• Measures of central tendency include the mean, median, and mode.
Reference: Measures of Central Tendency http://regentsprep.org/REgents/math/ALGEBRA/AD2/measure.htm
Mean:
The mean (average) is a measure of central tendency,
that is the “center” of the data. The mean is the sum of a
set of data divided by the number (count) of the data. It is
often referred to as “x-bar” using the symbol
Median:
The median is the middle value (or the mean of the
middle two values, when the data is arranged in numerical
order). The median is calculated by listing the data in
ascending order and then finding the value in the middle of
the list. Think of the median as the middle of a highway.
Mode:
The mode is the value (number) that appears the most.
It is possible to have more than one mode, and it is
possible to have no mode.
229.
Evelyn A. Catt, 2015
Meaningful Uses of Data
• Identify trends and patterns.
• Measure the impact of process changes.
• Monitor and sustain improvements.
• Compare organizational performance to industry
benchmarks and government mandated standards.
• Increase understanding and take action!

Value of Data Display
• Graphs can be used to visually summarize relationships between
variables, especially if the data set is large.
• They can be used in reports to enhance readability or underscore a
particular statement about a data set.
• Graphs can appeal to visual memory in ways that plain summary
tables cannot.
• Graphs can misrepresent relationships between variables or promote
inaccurate conclusions if not used correctly.

Questions to Guide Data Display
• What is the target problem?
• What are the target measures?
– Process (Little dots) focused on process steps
– Outcome (BIG dots) system or population measures
– Balancing (new problems caused by process changes)
– Are the measures quantitative or qualitative?
• Who is the target audience?
• What are the key points to be illustrated?

Evelyn A. Catt, 2015
Charts for Measuring
Variation & Change*
*Not inclusive of all chart types233.
Evelyn A. Catt, 2015
Using Run Charts for Data Display
• “Improvement takes place over time. Determining if
improvement has really happened and if it is lasting
requires observing patterns over time.
• Run charts are graphs of data over time and are one of
the most important tools for assessing the effectiveness of
change.”
Source URLs: http://www.ihi.org/resources/Pages/Tools/RunChart.aspx
http://app.ihi.org/Workspace/tracker/
234.
Evelyn A. Catt, 2015
Benefits of Run Charts
• They help improvement teams formulate aims by depicting
how well (or poorly) a process is performing.
• They help in determining when changes are truly
improvements by displaying a pattern of data that you can
observe as you make changes.
• They give direction as you work on improvement and
information about the value of particular changes.
Source URLs: http://www.ihi.org/resources/Pages/Tools/RunChart.aspx

235.
Evelyn A. Catt, 2015
Control Chart
• A Control Chart is used to monitor performance and draw conclusions
about whether the process is in control (common cause variation only)
or is out of control (affected by special cause variation, unpredictable).
• An X-Bar control chart is used to monitor variable data.
• A P-Chart control chart is used to monitor attribute data and error rates.

Pareto Chart
• The purpose of a Pareto Chart is to assess the most frequently occurring
errors/defects by category. It is used to highlight the most significant issues
among a large set of factors (often referred to as the “80/20” rule).
• The Pareto Chart contains both a bar and a line graph.
– Individual values are represented in descending order by bars.
– The cumulative total is represented by the line.
Reference & Diagram Source: http://en.wikipedia.org/wiki/Pareto_chart 237.

Pareto Chart Example
• A Pareto Chart showing reasons for arriving late at work.

Evelyn A. Catt, 2015
Frequency Plot (Histogram)
• A Frequency Plot (histogram) depicts the frequency of
observations occurring in a certain range of values.
• An important way of summarizing data is by measuring the average
“spread” or variation between each data point and the mean.
• A commonly used term in statistics for measuring this variation is
the standard deviation.
Spread

Distribution
Y axis
X axis239.
Evelyn A. Catt, 2015
Interpreting Frequency Plot Data
Common Cause Variation Special Cause – BimodalSpecial Cause – Outlier
Outlier
• Frequency Plots help us to understand if the variation that is present in a
process is the result of:
– Common Cause Variation (natural variation within a process)
– Special Cause Variation (unpredictable or extreme variation)
– Special Cause - Bimodal Variation (one system is using 2 different processes)
240.
Evelyn A. Catt, 2015
Impact of Outliers
• Understanding the impact of outliers is important because just one
extreme outlier in either direction can distort the mean and give a
very erroneous impression of performance (positive or negative).
• A high standard deviation (sigma) value is an indication there may
be extreme outliers that warrant further investigation and validation.
LOW outlier pulls the
mean value DOWN
HIGH outlier pulls
the mean value UP
Always investigate extreme
outliers to validate the data
Special Cause – Outlier

Process Capability
Reference: http://en.wikipedia.org/wiki/Process_capability_index
Diagram Source: http://www.qualitytrainingportal.com/resources/problem_solving/images/process_capability.gif
• Process capability measures the ability of a process to produce output
within certain specifications.
– Centering: Put the process on target (accuracy)
– Spread: Reduce variation in the process (precision)
244.
Evelyn A. Catt, 2015
Process Capability• As the process capability improves, the error rate (DPMO = defects per
million opportunities) will decrease and the Sigma level will increase:
6 Sigma = 3.4 DPMO
5 Sigma = 233 DPMO
4 Sigma = 6,210 DPMO
3 Sigma = 66,800 DPMO
2 Sigma = 308,540 DPMO

Specification Limits
Reference: http://www.six-sigma-material.com/SPC-Charts.html
Diagram Source: http://www.competitivexpert.com/files/Image/processvariationa.jpg
• Specification Limits are defined by the customer. They are one element
of the “Voice of the Customer” and may be modified over time.
• LSL = Lower Specification Limit USL = Upper Specification Limit
246.
Cp = Process Capability
• Note the Cp value listed under each
diagram, which is a simple measure
of process capability.
• A process is capable if almost all of
the measurements fall within the
upper and lower specification limits.

Accuracy vs. Precision
• Accuracy: Is a measure of the average distance from the target.
• Precision: Is a measure of the average distance from each other.

248.
Evelyn A. Catt, 2015
Improving Process Performance
• There are two aspects of improving process performance:
– Align the process to a target value (centering) = increased accuracy
– Reduce variation (spread) = increased precision
• Achieving one without the other is of limited value.

The Normal Distribution
• Over time, most processes tend to follow a Normal Distribution or bell
shaped curve.
• The Normal Distribution is important in statistics because of the relationship
between the shape of the curve and the standard deviation.
Y = ƒ(x)
Variation
Average
Y axis
X axis
250.
Evelyn A. Catt, 2015
The Normal Distribution
• One way of demonstrating the relationship between the standard deviation
(sigma) and the shape of the curve is to use sigma as a “measuring rod” to
describe how far we are away from the mean (average).
-3s -2s -1s +1s +2s +3s
+/-3s =99.73%
+/-2s =95.45%
+/-1s =68.27%
251.
Evelyn A. Catt, 2015
The Normal Distribution
• Another property of the normal distribution is the area under the curve gives us
the probability of a data point being drawn from this portion of the distribution.
– This allows us to predict how a process will perform over time.
• Almost all of the area (99.73%) of the normal distribution is contained between -
3 sigma and +3 sigma from the mean. Only 0.27% of the data falls outside 3
standard deviations from the mean:
-3s -2s -1s +1s +2s +3s
+/-3s =99.7% 252.
Evelyn A. Catt, 2015
What Lies Beneath
• Although the average (mean) is commonly used for reporting key
performance metrics, it is imperative to understand the range of data
points that contribute to the mean value. This is essential to:
– Understand the degree of variation in a process.
– Recognize the impact of outliers on the mean.
– Detect potential errors in the data.
Diagram Source: http://aviationhumor.net/wp-content/uploads/2010/11/shark-fin.jpg
253.
Evelyn A. Catt, 2015
Sub-Populations
• Many performance metrics are a combined average for multiple sub-
populations. It is important to review the data for each sub-population,
to understand the level of performance and sources of variation in
each area (example: patient satisfaction scores by nursing unit).
