Do you have a favorite soup? Do you like a Lean Gumbo? Or do you prefer a Six Sigma Stew? The
strength of your efforts depends upon what goes in the bowl. Why limit yourself? Let the
situation serve up the soup. Use all your options – Lean and Six Sigma – to achieve your goals and
ensure your success. View the full infographic here.
Lean
• PDCA – A rapid cycle improvement method (Plan – Do – Check – Act)
• A3 – A one-page, living document describing a process problem, the root cause analysis and potential
countermeasures
• 5S – A five-step organization technique to create and maintain an intuitive workspace (Sort, Set In Order, Shine,
Standardize, Sustain)
• 8 Wastes – The top eight elements that get in the way of process flow (Defects, Overproduction, Waiting, Non-
Utilized Talent, Transportation, Inventory, Motion, Extra-Processing)
• Value Stream Maps – Visual display of key steps including process data
• Flow – The unimpeded movement of a process
• Pull – Allowing customer demand to dictate process flow
• Spaghetti Map – Visual display of the wasted motion of individuals in a given workspace
• Process Walks – Interviews where the work occurs, with those who work in the process to better understand the
current state
• Batch Sizing – The practice of determining the smallest number of units to efficiently process at a time
• Standard Work – The agreed upon best method to accomplish a given task
• Work Cell Design – The layout of a workspace that results in the least amount of wasted motion for the workforce
• Single-Piece Flow – Processing each unit through to completion as opposed to creating batches
Lean Focuses on
• Reducing waste
• Maximizing flow
• Removing steps that don’t add value for the customer
• Using a holistic approach that builds a culture
Six Sigma
• DMAIC – A five-step process improvement method (Define, Measure, Analyze, Improve, Control)
• Project Charter – A one-page document that lays out the process problem, goal, scope, timeline and basic outline
of an improvement project
• Data Collection Plan – A guide to what data will be collected, by whom, how and when
• Basic Statistics – Measures of the average, median, range and standard deviation of any data set
• Histogram – A Graph that provides a snapshot of a data set displaying the spread, shape, average and range of
the data
• Pareto Chart – A cascading Bar Chart that displays the sources of process issues from the biggest source to the
smallest
• Measurement Systems Analysis – A way to test the accuracy, repeatability, reproducibility and precision of data
collection
• Hypothesis Testing – A way to provide statistical rigor to theories about the root causes of process issues
• Design of Experiments – Controlled tests to assess the effectiveness of different ways to run a process with the
goal of picking the best conditions, materials and methods
• Statistical Process Control – Monitoring a process to ensure that it consistently meets customer requirements
• Control Chart – A powerful time plot used in statistical process control signals the presence of special cause
variation in a process
Six Sigma focuses on
• Reducing variation
• Validating hypotheses with statistics
• Using the Martial Arts analogy to indicate knowledge level
• Using a 5-step method to complete improvement projects
It doesn’t matter where the tool comes from – what matters is solving the problem!
Problems Solved at the Root
• “Why is it that we never have enough time to do it right the first time, but we always have enough time to do it
over?” – Jack Bergman
Error Reduction
• “The only real mistake is one from which you learn nothing.” – Henry Ford
Increased Capacity
• “The future depends on what we do in the present.” – Mahatma Gandhi
Greater Efficiency
• “Efficiency is doing better what is already being done.” – Peter Drucker
Operational Excellence
• “We are what we repeatedly do. Excellence, then, is not an act, but a habit.” – Aristotle
Lean and Six Sigma are two great toolkits and together they provide all the support you
need to delight customers, reduce costs and build strong teams. Embrace the power of
“Yes, and” instead of “Either or” – life is richer with options!
