Question 2
During a Kaizen Event, a team is using the 5 Whys technique to analyze a production delay issue. After the fifth "Why?" they identify that the root cause is a lack of regular maintenance on machinery, which has led to frequent breakdowns. What is the main benefit of using the 5 Whys technique in this scenario?
-
A
It encourages brainstorming multiple solutions to the problem before identifying a root cause.
-
B
It allows the team to uncover the underlying root cause of the problem systematically by drilling down from the surface-level symptoms.
-
C
It helps break down a complex issue into simpler, smaller problems that can each be addressed individually.
-
D
It focuses on analyzing data metrics to quantify the impact of each identified cause on the problem.
Reveal correct answer
Correct answer: B
A.
The 5 Whys technique is focused on uncovering the root cause, not brainstorming multiple solutions at the initial stage.
B.
The 5 Whys technique is designed to delve into the root cause of a problem by asking "Why?" multiple times until reaching the most fundamental reason behind the issue. This method encourages a deeper understanding of the problem rather than stopping at surface-level symptoms.
C.
While it does break down the problem, the goal is to find one root cause, not separate smaller issues.
D.
The technique emphasizes uncovering causation rather than quantifying the impact through data metrics.
