Lean Six Sigma is a powerful combination of two Continuous Improvement methods. “Lean” is about speed – reducing non-value-added activities (or waste), to improve process cycle times. “Six Sigma” is about quality – reducing process variation and defects to near-perfect zero, translating to a 99.9997% yield.
Improving Process Cycle Time isn’t about doing things faster. It’s about understanding what the customer, the business, or other key stakeholders value, and eliminating everything else. Lean is about the relentless reduction of the Eight Deadly Sources of Waste:
Eight Deadly Sources of Waste
“There is surely nothing quite so useless as doing with great efficiency what should not be done at all.”
– Peter Drucker, 1963, Harvard Business Review
Six Sigma is a data-driven, analytical approach to improve quality. It’s about using statistical methods to understand trends and root causes that reduce variation. While Six Sigma was pioneered by Motorola in the 1980’s, it has grown beyond manufacturing to help companies improve their logistics, customer service, and other back office operations.
Building a Culture of Continuous Improvement
How do companies educate and engage leaders and line workers to relentlessly improve the business? It can start with a simple pilot program.
- Educate key leaders on the purpose, the potential and the journey
- Engage a “Project Sponsor” to Charter a project by defining the scope, objectives, baseline and target measures. Choose a project that employees care about and where incremental progress will motivate the team.
- Select an experienced resource to engage line workers in executing the Project Charter, by using simple Lean Six Sigma tools (Process Maps, 5 Why’s, Polka-Yolk, Fishbone diagrams…)
- Have the team present mid-week “pitchouts” to leadership, to share their progress, interim findings and feedback
- Ask the team to prioritize short-term and long-term improvement ideas
- Allow the team to internally market their successes and learnings to generate interest in future efforts
- Encourage leaders to Sponsor other, future initiatives
What’s So Unique?
When done correctly, employees are armed with simple tools to improve the processes they care about. They are engaged in making their jobs more enjoyable, by taking control over improving the things they do every day. It provides value to the business and instills value in the employee.
Lean Six Sigma starts with a “Charter” that is written by a “Sponsor”. This simple step ensures proper expectations of scope, objectives, and accountability.
- Once the project is appropriately “Defined”, data is gathered as part of the “Measure” phase to understand the current state.
- The data is then “Analyzed” to understand root cause and suggest possible countermeasure.
- During the “Improve” phase, potential solutions are evaluated and prioritized regarding their merit.
- The “Control” phase is used to pilot and implement the solution and understand the level of improvement that was achieved.
Once stabilized and understood, future projects are again “Defined” to drive the continuous improvement.
|Create a training program for sponsors, project managers (belts), employees||Don’t use it to implement your own ideas – if you already know the answer, just implement that…don’t waste the team’s time|
|Create a desirable career path for Lean Six Sigma facilitators||Don’t cut corners. Don’t be impatient. Don’t skimp on Charter Writing. Don’t jump from Define to Control|
|Leverage skilled resources to pilot a program to ensure initial success and to build momentum||Don’t allow Sponsors to disengage, or team members to dishonor time commitments|
|Arm employees with simple tools and let them discover and present their fact-based findings and recommendations||Don’t scope projects too large or allow for scope creep.|
|Trust the methodology and project phases: Define, Measure, Analyze, Improve, Control||Don’t allow the team to fall victim of “analysis paralysis”|
