Lean or Six Sigma - Which is Better? (Share your Comment Below)

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.

Lean Concepts & Tools

• 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 Concepts & Tools

• 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!

Lean + Six Sigma Common Benefits

Stronger Customer Focus

“Live in a constant state of awesomeness!” – Kimberly Fleming

Engaged Workforce

“Customers will never love a company unless employees love it first.” – Simon Sinek

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

Minimized Costs

“Creativity before cash!” – Mike Osterling

Maximized Profits

“Profit in business comes from repeat customers. Customers that boast about your product or service and bring friends with them.” – W. Edwards Deming

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!
