,1. Multiple Choice: Which of the following is a key principle of Lean Six
Sigma?
A) Reduction of process variation
B) Increase in process complexity
C) Decrease in customer satisfaction
D) Expansion of supplier base
Correct Answwer: A) Reduction of process variation
Rationale: Lean Six Sigma focuses on improving process efficiency by
reducing variation, which can lead to defects and inefficiencies.
2. True/False: Continuous improvement in Lean Six Sigma is only focused
on manufacturing processes.
Answwer: False
Rationale: Continuous improvement applies to all areas of an
organization, not just manufacturing, and aims to enhance processes
through incremental changes.
3. Fill-in-the-Blank: The _______ is a graphical tool used in Six Sigma to
identify potential causes of a problem.
Correct Answwer: Fishbone Diagram
Rationale: The Fishbone Diagram, also known as the Ishikawa diagram,
helps in identifying many possible causes for an effect or problem and
sorts ideas into useful categories.
, 4. Multiple Choice: In the context of Quality Management, 'Poka-Yoke'
refers to:
A) A type of control chart
B) A Japanese term for continuous improvement
C) An error-proofing technique
D) A method for demand forecasting
Correct Answwer: C) An error-proofing technique
Rationale: 'Poka-Yoke' is a Japanese term that means 'mistake-proofing'
and is used to design processes in a way that prevents errors.
5. True/False: The 5S methodology originated from Total Quality
Management (TQM) principles.
Answwer: False
Rationale: The 5S methodology originated in Japan and is a workplace
organization method that uses a list of five Japanese words: seiri, seiton,
seiso, seiketsu, and shitsuke.
6. Fill-in-the-Blank: The process of determining the critical path in project
management is known as _______.
Correct Answwer: Critical Path Method (CPM)
Rationale: The Critical Path Method (CPM) is a step-by-step project
management technique for process planning that defines critical and
non-critical tasks.
