Questions about methods used for problem solving. How to analyze a problem in depth, and how to make sure concern does not occur again.

• 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%
