Read the first 7 Tools and Techniques in Lean flashcards as text

  1. Which statement best describes the relationship between Lean and Six Sigma when combined as 'Lean Six Sigma'?

    Answer: Lean eliminates waste and improves flow while Six Sigma reduces variation and defects

    Lean Six Sigma combines Lean's waste elimination and flow improvement with Six Sigma's statistical approach to reducing process variation and defects.

  2. An Andon cord is pulled on an assembly line. According to Lean principles, what should happen immediately?

    Answer: The line stops (or alerts management) so the problem can be resolved before it spreads

    Pulling an Andon cord signals an abnormality; Lean principles require stopping to fix the problem immediately rather than passing defects downstream.

  3. What is the core purpose of a 'red tag' area used during the Sort phase of 5S?

    Answer: Hold items of questionable necessity until a disposition decision is made

    Red-tagged items are moved to a holding area where teams decide within a set timeframe whether to use, relocate, or dispose of them.

  4. In value stream mapping, what does 'value-added time' refer to?

    Answer: Time during which the product is actually being transformed in a way the customer is willing to pay for

    Value-added time is only the portion of processing time where material is being physically transformed or shaped in ways the customer values and would pay for.

  5. A facility implements 'Standard Work Combination Sheets.' What information do these documents capture?

    Answer: The interaction of operator time, machine time, and walking time for each work element

    Standard Work Combination Sheets graphically show how manual work time, auto-processing time, and walking time combine within one takt time cycle.

  6. Which of the following is an example of 'overprocessing' waste in Lean?

    Answer: Applying a higher-quality surface finish than the customer specification requires

    Overprocessing means doing more work, adding more features, or applying higher precision than the customer actually requires or values.

  7. When using a Pareto chart to prioritize improvement efforts, which category should typically be addressed first?

    Answer: The category with the highest cumulative impact, appearing leftmost in the chart

    Pareto analysis directs teams to address the tallest bars first—the vital few categories that account for the majority (often ~80%) of total occurrences.
