Insider Knowledge
Terminology
Greeting Salutations
Example Conversation
Insider
Have you Gemba’d today?
Outsider
Gemba what? What do you mean by that?
Insider
It means going to the actual workplace where the process occurs to observe and understand it—key to honest problem-solving.
Outsider
Ah, that makes sense now. I’ll clue into the real environment next time.
Cultural Context
Encourages direct observation instead of relying on reports, reflecting Lean Six Sigma’s emphasis on firsthand data gathering and respect for the actual work environment.
Inside Jokes
"Another SIPOC pic for the fridge!"
SIPOC diagrams (Suppliers, Inputs, Process, Outputs, Customers) are so often created and shared that joking about collecting them like fridge magnets reflects the ubiquity and sometimes tediousness of standard tools.
"You can’t improve what you don’t measure... except your patience."
This humorously references the obsession with data measurement in Lean Six Sigma, contrasting process metrics with the human element of tolerance during lengthy initiatives.
Facts & Sayings
„DMAIC“
A core problem-solving framework standing for Define, Measure, Analyze, Improve, Control; signaling methodical process improvement steps insiders swear by.
„Go to the Gemba“
An exhortation meaning to go to the actual place where work happens to observe and gather facts firsthand, emphasizing direct engagement over assumptions.
„Poka-Yoke“
Refers to a 'mistake-proofing' technique designed to prevent errors; using this term marks familiarity with practical defect prevention.
„Kaizen event“
A short, focused workshop dedicated to rapid process improvement, showing commitment to continuous, incremental gains.
„Project tollgate“
A checkpoint or review stage in a project to ensure quality and readiness before proceeding, demonstrating disciplined governance.
Unwritten Rules
Don’t shortcut DMAIC phases.
Skipping steps undermines rigor and credibility; adherence signals respect for the methodology and increases chances of successful outcomes.
Bring data, not opinions, to discussions.
Decisions informed by data maintain objectivity and professionalism, reinforcing Lean Six Sigma's reputation as a scientific approach.
Always seek root cause beyond the surface.
Superficial fixes are frowned upon; diving deep demonstrates thoroughness and mastery of problem solving.
Share war stories humbly.
Storytelling about past projects builds camaraderie but must be balanced with humility to avoid appearing boastful or dogmatic.

Get-Started Steps
Time to basics: 3-4 weeks
1
Learn Core Concepts
2-3 hoursBasic
Summary: Study Lean and Six Sigma basics, key terms, and foundational principles using reputable introductory materials.
Details: Begin by immersing yourself in the foundational concepts of Lean and Six Sigma. This includes understanding the history, goals, and the synergy between Lean (focused on waste reduction) and Six Sigma (focused on reducing process variation). Learn key terms such as DMAIC, value stream, Kaizen, and types of waste (muda). Use reputable introductory materials like whitepapers, official guides, and summary videos. Beginners often struggle with jargon and the breadth of concepts—take notes and create a glossary for yourself. Focus on grasping the big picture before diving into tools or methodologies. This step is crucial because it provides the language and mental framework needed to engage with the community and further learning. Evaluate your progress by being able to explain the difference between Lean and Six Sigma, list the main wastes, and describe the DMAIC cycle in your own words.
2
Join Practitioner Communities
1-2 hoursBasic
Summary: Register on Lean Six Sigma forums or social groups to observe discussions and ask beginner questions respectfully.
Details: Engage with the Lean Six Sigma community by joining online forums, professional groups, or social media communities dedicated to process improvement. Start by observing discussions to get a sense of the culture, common topics, and etiquette. When ready, introduce yourself and ask thoughtful beginner questions—avoid asking for shortcuts to certification or overly broad questions. Common challenges include feeling intimidated by experienced members or not knowing how to contribute. Overcome this by being respectful, showing you've done some homework, and asking for advice on beginner resources or common pitfalls. This step is important for networking, gaining real-world insights, and staying motivated. Progress can be measured by your ability to participate in discussions, receive feedback, and identify recurring themes or challenges in the field.
3
Map a Simple Process
2-3 hoursIntermediate
Summary: Select a basic process from daily life or work and create a process map using Lean Six Sigma techniques.
Details: Apply your foundational knowledge by mapping a simple process—such as making coffee, onboarding a new employee, or handling an email request. Use basic process mapping tools like flowcharts or SIPOC diagrams. This hands-on activity helps you internalize Lean Six Sigma thinking by visualizing steps, identifying potential wastes, and considering where variation might occur. Beginners often overcomplicate their maps or miss key steps; keep it simple and focus on clarity. Use templates or examples from reference materials to guide you. This step is vital because process mapping is a core skill in Lean Six Sigma, forming the basis for all improvement work. Assess your progress by sharing your map with peers or online communities for feedback and being able to explain each step and its purpose.

4
Practice Identifying Waste
2-4 hoursIntermediate
Summary: Observe a real or simulated process and list examples of the 8 wastes (muda) using Lean principles.
Details: Take your process mapping further by observing a real-world or simulated process (at work, home, or via case studies) and identifying instances of the 8 wastes: defects, overproduction, waiting, non-utilized talent, transportation, inventory, motion, and extra-processing. Use a checklist or worksheet to guide your observations. Beginners often struggle to distinguish between types of waste or overlook less obvious examples. Overcome this by reviewing examples and discussing your findings with others in the community. This activity is essential because waste identification is a foundational Lean skill and a prerequisite for meaningful process improvement. Evaluate your progress by accurately categorizing wastes and suggesting at least one improvement idea for the process you observed.
5
Participate in a Kaizen Event
1-2 daysAdvanced
Summary: Join or observe a small-scale improvement event (Kaizen) in your workplace or through a simulation to experience real application.
Details: Seek out opportunities to participate in or observe a Kaizen event—a focused, short-term project aimed at improving a specific process. If your workplace offers such events, volunteer to join as a team member or observer. Alternatively, look for virtual simulations or case studies that walk through a Kaizen event. Beginners may feel overwhelmed by the fast pace or unsure how to contribute; prepare by reviewing the event's objectives and roles beforehand. Take notes on how problems are identified, solutions brainstormed, and results measured. This step is important because it exposes you to Lean Six Sigma in action, builds teamwork skills, and demonstrates the practical impact of the methodology. Measure your progress by reflecting on what you learned, how you contributed, and identifying steps you could replicate in your own context.
