Read the first 7 Lean Six Sigma Fundamentals flashcards as text

  1. During the Analyze phase of DMAIC, which tool is most commonly used to identify root causes by exploring cause-and-effect relationships?

    Answer: Fishbone (Ishikawa) diagram

    The fishbone diagram organizes potential causes into categories (e.g., Man, Machine, Method) to systematically explore root causes of a problem.

  2. What does the 'C' represent in the DMAIC acronym?

    Answer: Control

    Control is the final phase of DMAIC, where teams implement control plans and monitoring systems to sustain the gains achieved.

  3. Which Lean tool is specifically designed to separate needed from unneeded items and remove the latter from the workspace?

    Answer: 5S — Seiri (Sort)

    Seiri (Sort), the first S in 5S, involves identifying and removing unnecessary items from the work area to reduce clutter and improve efficiency.

  4. In a Six Sigma project, a Black Belt calculates that a process yields 3.4 defects per million opportunities. What sigma level does this correspond to?

    Answer: 6 sigma

    Six Sigma is defined by achieving no more than 3.4 DPMO, accounting for a 1.5-sigma long-term shift from the short-term process mean.

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

    Answer: Applying a finish coat that exceeds customer specification requirements

    Overprocessing occurs when more work is done on a product than what the customer actually requires or values, adding cost without adding value.

  6. What is the role of a 'Champion' in a Six Sigma deployment?

    Answer: Provide executive sponsorship and remove organizational barriers for projects

    Champions are senior leaders who sponsor Six Sigma projects, align them with business strategy, and remove obstacles that project teams cannot resolve on their own.

  7. A team is using a 'spaghetti diagram' during their Lean analysis. What does this tool primarily help identify?

    Answer: Unnecessary physical movement of people or materials

    A spaghetti diagram traces the physical path of people or materials through a process, making excessive motion and inefficient layouts visually obvious.
