Which of the following is NOT one of the 5S pillars?
Sort
Simplify
Standardize
Shine
The 5S pillars are Sort, Set in Order, Shine, Standardize, and Sustain. "Simplify" is not one of the official 5S names. It is sometimes colloquially used but is not part of the formal 5S framework.
In Lean terminology, what does "Muda" refer to?
Process standardization
Root cause analysis
Continuous improvement
Waste
Muda is the Japanese term for waste in Lean. It represents any activity that does not add value from the customer's perspective.
Which Lean principle emphasizes producing only what the customer needs when they need it?
Standardize
Pull
Push
Flow
The Pull principle means production is driven by actual customer demand rather than forecasts. It prevents overproduction by only making items when requested.
What is the first step in the PDCA continuous improvement cycle?
Do
Plan
Check
Act
The PDCA cycle begins with the Plan phase, where objectives are defined and a strategy is developed. It sets the foundation for testing and implementing improvements.
Which of these is NOT one of the seven wastes identified in Lean?
Waiting
Transportation
Overproduction
Telemarketing
The seven wastes are Transportation, Inventory, Motion, Waiting, Overproduction, Overprocessing, and Defects. "Telemarketing" is unrelated and not one of the Lean wastes.
Which tool is used to visually map the flow of materials and information in a process?
5 Whys
Kanban
Value Stream Mapping
Poka-Yoke
Value Stream Mapping creates a visual representation of material and information flows across a process. It identifies areas of waste and opportunities for improvement.
Which root cause analysis technique involves asking "Why?" repeatedly, typically five times?
Pareto Analysis
5 Whys
Fishbone Diagram
SPC Chart
The 5 Whys technique drills down to the root cause by asking why a problem occurred up to five times. It is a simple, yet powerful, Lean tool for causal analysis.
How is takt time calculated in a production environment?
Available production time ÷ actual output
Customer demand ÷ available production time
Available production time ÷ customer demand
Cycle time × batch size
Takt time is the rate at which products must be completed to meet customer demand, calculated as available production time divided by customer demand.
In Lean, what is a Kanban system primarily used for?
Visual scheduling and pull signaling
Standardizing work instructions
Root cause analysis
Eliminating defects
Kanban is a visual signaling system used to trigger production or replenishment in a pull system. It helps manage workflow and control inventory.
If machines on a line frequently stop because parts arrive late, this situation exemplifies which type of waste?
Defects
Overproduction
Overprocessing
Waiting
When equipment is idle due to lack of parts, it falls under Waiting waste. This type of waste occurs whenever people, machines, or processes wait for materials or information.
Which tool organizes potential causes of a problem into categories like Man, Machine, Method, and Material?
Fishbone Diagram
Control Chart
Scatter Plot
Pareto Chart
The Fishbone Diagram, also called Ishikawa or cause-and-effect diagram, categorizes potential causes under headings such as Man, Machine, Method, and Material.
When cycle time exceeds takt time on a production line, what is the most likely result?
Line will produce ahead of demand
Excess idle time
Perfect synchronization
Backlog and missed customer deliveries
If cycle time is longer than takt time, production cannot keep up with customer demand, leading to backlog and potential delays in delivery.
What is the primary purpose of standard work in Lean?
Visualize the value stream
Calculate takt time
Ensure consistent, repeatable processes
Identify root causes
Standard work defines the best known sequence of steps and set times for tasks, ensuring consistency and minimizing variation in process performance.
What does the term Kaizen most closely describe?
Quality audit procedure
A large-scale process redesign
Incremental, continuous improvement
Monthly financial review
Kaizen refers to continuous, incremental improvements made by all employees. It fosters a culture where small changes are regularly implemented to improve efficiency.
Which Lean method is specifically designed to prevent mistakes by making it impossible to commit an error?
Poka-Yoke
5 Whys
Kanban
Heijunka
Poka-Yoke means mistake-proofing or error-proofing. It involves mechanisms or design features that prevent defects by making errors immediately obvious or impossible.
If a production line has 480 available minutes per day and customer demand is 120 units, what is the takt time?
4 minutes
8 minutes
6 minutes
2 minutes
Takt time = Available production time ÷ Customer demand = 480 ÷ 120 = 4 minutes per unit. This sets the pace to meet demand.
A process has a total lead time of 10 minutes, with only 2 minutes being value-added work. What is the value-added ratio?
200%
50%
80%
20%
Value-added ratio = (Value-added time ÷ Total lead time) × 100 = (2 ÷ 10) × 100 = 20%. It highlights non-value time in the process.
What does SMED stand for in Lean methodology?
Systematic Manufacturing Engineering Development
Single-Minute Exchange of Dies
Simple Maintenance and Equipment Debugging
Standardized Method for Equipment Design
SMED stands for Single-Minute Exchange of Dies, a method to reduce setup or changeover times to under 10 minutes, improving flexibility and flow.
Which Lean technique is focused on leveling production to reduce unevenness and overburden?
5 Whys
Heijunka
Poka-Yoke
Kaizen
Heijunka is the practice of production leveling to smooth out the mix and volume of work, reducing peaks and troughs that cause waste and overburden.
After constructing a fishbone diagram, which tool is best to prioritize the most significant causes?
Pareto Chart
Flowchart
Scatter Plot
Control Chart
A Pareto Chart ranks causes by frequency or impact, applying the 80/20 principle. It highlights the few critical issues to address first after a fishbone analysis.

Cheat Sheet

  1. Understand the Five Lean Principles - Lean is all about maximizing value and minimizing waste through five core ideas: Define Value, Map the Value Stream, Create Flow, Establish Pull, and Pursue Perfection. Mastering these principles helps you spot inefficiencies and keep processes running like a well-oiled machine. Learn more on Process Navigation
  2. Identify the Eight Types of Waste (TIMWOODS) - TIMWOODS stands for Transport, Inventory, Motion, Waiting, Overproduction, Overprocessing, Defects, and Skills. Recognizing and categorizing these wastes is the first step toward cutting out anything that doesn't add value. Dive into TIMWOODS on LearnLeanSigma
  3. Master the 5S Methodology - The 5S framework (Sort, Set in Order, Shine, Standardize, Sustain) transforms chaotic workspaces into lean, efficient environments. By organizing everything in sight, you boost safety, speed, and satisfaction. Explore 5S at Lean Six Sigma Institute
  4. Explore Value Stream Mapping (VSM) - VSM is like drawing a treasure map of your process flow, highlighting every step from concept to delivery. Once you see the full picture, you can strike out the hidden bottlenecks and speed up the journey. Chart your flow on Six Sigma Study Guide
  5. Learn about Kaizen (Continuous Improvement) - Kaizen champions small, daily tweaks that add up to big gains over time. Involve everyone, from interns to CEOs, in brainstorming ways to make processes cleaner and faster. Start Kaizen with Six Sigma Study Guide
  6. Understand the Pull System - Instead of pushing products out in huge batches, a pull system produces only what's needed when it's needed. This approach slashes overproduction and keeps inventory lean. Discover the Pull System on Process Navigation
  7. Recognize the Importance of Flow - A smooth, uninterrupted workflow is like a fast-moving river - no pools, no logjams. Ensuring flow means fewer delays, happier customers, and a team that's in sync. See Flow in Action on Process Navigation
  8. Study Standard Work Instructions - Clear, step-by-step instructions ensure everyone performs tasks the same way, every time, leading to consistent quality and fewer mistakes. Consistency breeds confidence and reliability. Get Standard Work tips at Lean Six Sigma Institute
  9. Explore Visual Management Tools - Tools like Andon boards light up when something goes off-track, giving real-time feedback and rallying the team to fix issues fast. It's like a process dashboard you can actually read at a glance. Check out Visual Management on Lean Six Sigma Institute
  10. Understand the Role of Leadership in Lean - Strong leaders model continuous improvement, empower teams to innovate, and celebrate small wins. Their mindset drives the culture that turns lean theory into daily practice. Read about leadership on Lean.org
