During the Improve phase, which activity involves generating a large number of creative solutions without immediate criticism or evaluation?
Answer: Brainstorming
Brainstorming encourages free generation of ideas in a judgment-free environment, which is essential early in the Improve phase to surface a wide range of potential solutions before narrowing down.
What does PDCA stand for in the context of implementing improvements during the Improve phase?
Answer: Plan, Do, Check, Act
PDCA (Plan, Do, Check, Act) is a structured improvement cycle used in the Improve phase to test solutions in a controlled way, evaluate results, and make adjustments before full implementation.
Which technique in the Improve phase involves physically walking through a process to observe waste and inefficiency firsthand?
Answer: Gemba walk
A Gemba walk means going to the actual place where work is done to observe the process directly, helping teams identify real-world waste and improvement opportunities that data alone might miss.
In Lean Six Sigma, which type of waste refers to unnecessary movement of people within a process?
Answer: Motion
Motion waste refers to any unnecessary physical movement by employees—such as walking, bending, or reaching—that does not add value to the product or service. Eliminating it is a key target in the Improve phase.
When a Yellow Belt team selects a solution to implement, which factor is LEAST important to consider?
Answer: The team leader's personal preference
Solution selection should be data-driven and objective, weighing feasibility, cost, and expected impact. Personal preferences introduce bias and are not a valid criterion in a structured Lean Six Sigma decision process.
What is the main purpose of creating a future-state value stream map during the Improve phase?
Answer: To visualize the ideal process after waste has been eliminated
A future-state value stream map shows what the process should look like after planned improvements are applied, helping the team set a clear target and guide implementation of waste-reduction changes.
