A graphical tool for ranking causes from most significant to least significant

  1. Check Sheet

  2. Cause and Effect Diagram

  3. Scatter Diagram

  4. Pareto Chart


Correct Option: D
Explanation:

To solve this question, the user needs to be familiar with different graphical tools used for quality improvement and problem-solving. The user also needs to understand the purpose and use of each tool.

Now, let's go through each option and explain why it is right or wrong:

A. Check Sheet: This option is incorrect. A check sheet is a tool used for data collection and tallying, not for ranking causes.

B. Cause and Effect Diagram: This option is incorrect. A cause and effect diagram, also known as a fishbone diagram, is used to identify and analyze the potential causes of a problem, not to rank causes.

C. Scatter Diagram: This option is incorrect. A scatter diagram is used to examine the relationship between two variables, not to rank causes.

D. Pareto Chart: This option is correct. A Pareto chart is a graphical tool used to prioritize and rank causes from most significant to least significant. It combines a bar chart and a line graph to visually represent the frequency or impact of each cause. The causes are ordered from left to right based on their contribution to the overall problem. The tallest bar represents the most significant cause, guiding improvement efforts towards addressing the vital few causes that contribute the most to the problem.

The Answer is: D. Pareto Chart

A methodology that measures the amount of variation in the measurement system arising from the measurement device and the people taking the measurement

  1. Gage R&R

  2. ANOVA

  3. Linearity

  4. Accuracy


Correct Option: A

A pictorial diagram showing possible causes for a given effect

  1. Affinity diagram

  2. Fishbone Diagram

  3. Deployment chart

  4. Scatter Diagram


Correct Option: B

AI Explanation

To answer this question, you need to understand the different types of diagrams used to analyze and identify causes for a given effect.

Option A) Affinity diagram - This option is incorrect because an affinity diagram is used to organize and group ideas or data based on their relationships or similarities. It is not specifically designed to identify causes and effects.

Option B) Fishbone Diagram - This option is correct because a fishbone diagram, also known as a cause and effect diagram or Ishikawa diagram, is a pictorial representation that is used to identify and analyze possible causes for a given effect. The diagram consists of a horizontal line (representing the effect) with several lines branching off from it (representing potential causes) resembling the skeleton of a fish. It is a commonly used tool in problem-solving and quality improvement processes.

Option C) Deployment chart - This option is incorrect because a deployment chart is a type of diagram used to visualize the process and sequence of steps involved in implementing a project or plan. It is not specifically designed to identify causes and effects.

Option D) Scatter Diagram - This option is incorrect because a scatter diagram is a graph that represents the relationship between two variables. It is used to determine whether a relationship exists between the variables and if so, the nature of that relationship. It is not specifically used to identify causes and effects.

The correct answer is B) Fishbone Diagram. This option is correct because a fishbone diagram is specifically designed to visually represent and analyze the possible causes for a given effect.

Correct Option: C

CTQ/Project Y matrix is used

  1. To prioritize CTQs

  2. To Identify the best measure for a CTQ

  3. To identify a CTQ easier to work on

  4. To identify Project Y metric which can be measured easily


Correct Option: B

AI Explanation

To answer this question, we need to understand what a CTQ (Critical-to-Quality) is and how the CTQ/Project Y matrix is used.

CTQs are the key characteristics or requirements that are critical for ensuring customer satisfaction. These characteristics may include aspects such as performance, reliability, cost, and functionality.

The CTQ/Project Y matrix is a tool used in Six Sigma and quality management to identify the best measure for a CTQ. The matrix helps in determining which Project Y metric (a metric that represents the performance of a process or product) is most closely related to a CTQ.

Let's go through each option to understand why it is correct or incorrect:

Option A) To prioritize CTQs - This option is incorrect because the CTQ/Project Y matrix is not used for prioritizing CTQs. It is used to identify the best measure for a CTQ.

Option B) To identify the best measure for a CTQ - This option is correct. The CTQ/Project Y matrix is used to determine which Project Y metric is most closely related to a CTQ, helping in identifying the best measure for the CTQ.

Option C) To identify a CTQ easier to work on - This option is incorrect. The CTQ/Project Y matrix does not help in identifying a CTQ that is easier to work on. It focuses on identifying the best measure for a CTQ.

Option D) To identify Project Y metric which can be measured easily - This option is incorrect. The CTQ/Project Y matrix does not specifically focus on identifying Project Y metrics that can be measured easily. It focuses on identifying the best measure for a CTQ.

The correct answer is B) To identify the best measure for a CTQ. This option is correct because the CTQ/Project Y matrix is used precisely for this purpose.

Which one is not a part of Process Management Chart ?

  1. Documentation

  2. Control Plan

  3. Response Plan

  4. Monitoring


Correct Option: B

AI Explanation

To answer this question, we need to understand the components of a Process Management Chart.

A Process Management Chart is a visual representation of the steps involved in managing a process. It typically includes various components such as documentation, control plan, response plan, and monitoring.

Let's evaluate each option:

Option A) Documentation - This option is a part of a Process Management Chart. Documentation is essential for capturing and recording important information related to the process.

Option B) Control Plan - This option is stated as the correct answer. However, it is incorrect. A control plan is typically included in a Process Management Chart as it outlines the actions and measures to control and manage the process.

Option C) Response Plan - This option is a part of a Process Management Chart. A response plan outlines the actions and measures to be taken in case of any issues or deviations from the defined process.

Option D) Monitoring - This option is a part of a Process Management Chart. Monitoring involves regularly observing and measuring the process to ensure that it is performing as intended.

Therefore, the correct answer is B) Control Plan, as it is indeed a part of a Process Management Chart.
