Free Lean Six Sigma Yellow Belt Measure Phase Tools Questions and Answers

Question 1

A project team is in the Measure phase and needs to collect data on the frequency of different types of customer complaints. They want a simple, manual tool to tally occurrences in real-time at the service desk. Which tool is most appropriate for this task?

Accepted Answer

Check Sheet

Answer

A Check Sheet is a structured form used to collect and organize data in real-time at the location where the data is generated. It is ideal for tallying the frequency of specific events, such as different types of customer complaints, making it the perfect tool for this scenario.

Question 2

Which of the following is a primary objective of creating a detailed Data Collection Plan during the Measure phase?

Accepted Answer

To ensure the data collected is relevant, accurate, and consistent.

Answer

The Data Collection Plan is a critical Measure phase tool that acts as a work instruction for gathering data. Its purpose is to define what data to collect, how to collect it, who will collect it, and when, ensuring the data is reliable and directly addresses the project's key questions.

Question 3

A team is analyzing a manufacturing process and is concerned that the measurement system itself might be contributing to the observed variation. They want to determine how much variation is due to the equipment (repeatability) versus the different operators using it (reproducibility). What analysis should they perform?

Accepted Answer

Gage R&R Study

Answer

A Gage R&R (Repeatability & Reproducibility) study is specifically designed to assess the variation within a measurement system. It quantifies the variation originating from the measurement device (repeatability) and the variation from the different people using the device (reproducibility).

Question 4

A team has collected data on a critical process metric and wants to understand its potential to meet customer specifications. They calculate a value that compares the spread of the process variation to the spread of the specification limits, assuming the process is centered. What have they calculated?

Accepted Answer

Process Capability (Cp)

Answer

Cp, the Process Capability, is a measure of the potential capability of a process. It is calculated as the ratio of the specification width (USL - LSL) to the process width (6-sigma), and it does not account for whether the process mean is centered within the specifications.

Question 5

To establish a baseline of the 'as-is' process, a Yellow Belt needs to create a visual representation that shows the sequence of activities, decision points, and flow of materials or information. Which tool would be most effective for this purpose?

Accepted Answer

Process Flow Diagram

Answer

A Process Flow Diagram, also known as a process map or flowchart, is a fundamental tool used in the Measure phase to visually document the steps of a process in sequential order. This helps the team understand the current state and identify areas for data collection and analysis.
