Questions and Answers
  • 1. 
    Assume I have the following data in a tally sheet Cause of customer dissatisfaction :Scratches IPart broke down I I I I I IWrong color IStrange noise when using I I IWhich arrangement would best fit the creation of a pareto ?
    • A. 

      Part broke down : 6 Strange noise : 3 Scratches : 1 Wrong color : 1 So that values being plotted are arranged in descending order

    • B. 

      Scratches 1 Part broke down 6 Wrong color 1 Strange noise when using 3 Summing up values is good enough to plot a chart

    • C. 

      Average number of claim by type of defect =11/4=2,7. Pareto value is 2,7

  • 2. 
    What are the other names of Ishikawa diagram ?
    • A. 

      Cause and effect diagram; fishbone diagram

    • B. 

      Cause and effect diagram, 4M diagram

    • C. 

      Fishbone diagram, 4M diagram

  • 3. 
    What is Ishikawa diagram ?
    • A. 

      It is way to formalize and display causes in a fishbone/tree shape, that helps conduct analysis

    • B. 

      It is stricltly limited to analyzing the cause linked to following issues : Man, Method, Mean, Maintenance

    • C. 

      It is based on asking the following questions : Who, what, where, when, why, how, how much

  • 4. 
    What is the main use of 6M diagram : (Machine, Method, Materials, Maintenance, Man and Mother Nature (Environment)) ?
    • A. 

      Looking at each branch of 6M avoids focusing on one single obvious cause and therefore enables deep root cause analysis

    • B. 

      Selecting one M at the very beginning of the analysis helps save time and enables quick action plan

    • C. 

      6M diagram should not be used. 4M diagram is to be used in the shopfloor, 7M if issue is companywise

  • 5. 
    At what quality tools children are usually good at ?
    • A. 

      Why ? Why ? Why ? .... -> The 5Whys method

    • B. 

      Is it still far away ? -> The "how long" method

    • C. 

      I don't like it -> the "Like / Don't Like" method

  • 6. 
    Why is "5 why" method interesting ?
    • A. 

      Because it avoids focusing on main obvious cause, by asking "why?" until real root cause is found (and it usually takes 3 to 5 whys)

    • B. 

      Because you have to ask "why" for each main issue (Man, Method, Mean, Materials, Maintenance) and it gives a wider scope

    • C. 

      Because it has been rated "most efficient quality tool" by Juran in the 1950's and it has won Deming Prize

  • 7. 
    Is it necessary to use analysis tools when solving a problem ?
    • A. 

      Yes in case of big problem, or recurrence

    • B. 

      Yes but in case of warranty claim only as it takes more time

    • C. 

      Yes for all problems

    • D. 

      It depends on the problem solving workgroup decision

  • 8. 
    Pick the line that has the more existing quality tools for analysis
    • A. 

      5Whys, 5W1H, Ishikawa, IS-IS not, Failure Tree

    • B. 

      5S, 8D report, Ishikawa, Pareto chart, Tally sheet

    • C. 

      5S, 8D report, 5mn review, checksheet, 5Whys

  • 9. 
    It it important to spend time on problem solving ? if yes, why ?
    • A. 

      Yes, because it enables to find the right root causes and therefore implement an efficient action plan to avoid recurrence

    • B. 

      Yes, because usually automotive customers ask you to think 2 weeks before answering

    • C. 

      No, you should not spend much time on problem solving, as next deliveries to the customer must be secured.

  • 10. 
    What is Pareto law ?
    • A. 

      80% of a problem is caused by 20% of the causes

    • B. 

      The first cause found for a problem is responsible of 80% of the problem

    • C. 

      You need to solve 80% of causes to decrease a problem by 20%
