Correct Answer: The total time it takes to fulfill an order, from receipt to delivery

Lead Time measures the total time it takes to fulfill a customer order, from the moment the order is received to the moment it is delivered.

Correct Answer: 80% of the problems come from 20% of the causes

The Pareto Principle, also known as the 80/20 rule, suggests that 80% of problems are caused by just 20% of the potential causes, allowing teams to focus on the most impactful issues.

Correct Answer: Collecting data on the current process performance

The Measure phase is dedicated to gathering data on how the process currently performs, providing a baseline for comparison after improvements are made.

Correct Answer: Identify the root cause of a problem by repeatedly asking "Why?"

The 5 Whys is a root cause analysis technique that involves asking "Why?" multiple times to drill down into the underlying causes of a problem.

Correct Answer: Compare the mean of a sample to a known population mean

The One Sample T-Test is a statistical test used to compare the mean of a sample to a known population mean to determine if there is a significant difference.

Correct Answer: Using visual cues to improve process transparency and efficiency

Visual Management involves using visual signals, such as signs, charts, and boards, to improve process visibility and ensure that performance is easily understood by all team members.
