Which tool would a team use to systematically generate a large number of improvement ideas from multiple team members simultaneously?
Answer: Brainstorming
Brainstorming is a structured idea-generation technique designed to produce many ideas from a group quickly without initial criticism.
A Kaizen event differs from a standard improvement project primarily because it:
Answer: Is a rapid, focused improvement activity completed in days
A Kaizen event (blitz) is an intensive, short-duration team effort — typically 3–5 days — to make rapid, targeted improvements.
In a process capability study, a Cp of 1.33 indicates that:
Answer: The process spread fits within the specification limits with margin
A Cp of 1.33 means the specification width is 1.33 times the process spread (±4σ), providing comfortable margin within spec limits.
Which of the following describes the purpose of a 'spaghetti diagram' in process analysis?
Answer: To trace the physical movement path of a product or person
A spaghetti diagram traces the actual physical path traveled by a product, person, or information, revealing unnecessary motion waste.
A team is selecting among five potential improvement solutions. They rate each solution on feasibility, impact, and cost using a numerical scale. This technique is called:
Answer: Weighted criteria matrix (decision matrix)
A weighted criteria matrix scores each option against defined criteria with assigned weights, providing an objective basis for selection.
In force field analysis, 'restraining forces' are best described as:
Answer: Factors that resist or hinder the change
Restraining forces oppose the desired change; reducing them (along with strengthening driving forces) is the goal of force field analysis.
Which process analysis metric measures the percentage of time a process is actually adding value relative to total lead time?
Answer: Process efficiency (value-added ratio)
Process efficiency (value-added ratio) = value-added time / total lead time, revealing how much of the elapsed time is truly productive.
