One graphical tool often used to help identify opportunities for improvement is

1. ANOVA

2. Cost/benefit analysis

3. Pareto Analysis

4. Control Charts

Correct Option: C
Explanation:

To answer this question, the user needs to be familiar with graphical tools used in process improvement.

Option A, ANOVA, is a statistical test used to analyze the difference between the means of two or more groups. ANOVA is not a graphical tool used for identifying opportunities for improvement, so it is not the correct answer.

Option B, Cost/benefit analysis, is a financial tool used to compare the costs of a project or decision to its potential benefits. While cost/benefit analysis can be useful for evaluating the feasibility of improvement opportunities, it is not a graphical tool. Therefore, it is not the correct answer.

Option C, Pareto Analysis, is a graphical tool used to identify the most significant sources of a problem or issue. The Pareto chart is used to show the frequency or volume of each source, allowing the user to prioritize which sources to address first. Pareto Analysis is a common tool used in process improvement, and it is the correct answer.

Option D, Control Charts, are graphical tools used to monitor the performance of a process over time. Control charts help identify when a process is out of control and may require corrective action. While control charts can be useful for identifying opportunities for improvement, they are not primarily used for that purpose. Therefore, option D is not the correct answer.

The Answer is: C. Pareto Analysis

Problem statement should address the following questions exceptâ€¦..

1. What is wrong ?

2. When and where does the problem occur ?

3. What is the cause ?

4. What is the impact ?

Correct Option: C

Process Management Chart does not contain

1. Project Plan

2. Documentation

3. Response Plan

4. Monitoring Plan

Correct Option: A

Project Leader wants to check the impact of experience in IT field and skill level on Efficiency Index. He takes experience as 1 yr & 3yrs and skill levels as High, Medium & Low. How many factors & levels he has and what should be the number of trials?

1. "2 Factors2 levels for one factor and 3 levels for another factor6 Trials"

2. "5 Factors2 levels for each factor32 Trials"

3. "3 Factors2 levels for each factor8 Trials"

4. "3 Factors3 levels for each factor27 Trials"

Correct Option: A

Project Milestone dates should be

1. Aggressive & Realistic

2. Aggressive & Unrealistic

3. Easier & Realistic

4. Simple & Realistic

Correct Option: A

#### AI Explanation

To answer this question, we need to understand the concept of project milestone dates.

Option A) Aggressive & Realistic - This option is correct because project milestone dates should be set aggressively to encourage a sense of urgency and drive the team to complete their tasks efficiently. However, these dates should also be realistic, meaning they should be achievable within the given constraints and resources.

Option B) Aggressive & Unrealistic - This option is incorrect because setting unrealistic milestone dates can lead to unnecessary stress and pressure on the team, which may result in poor quality work or missed deadlines. Unrealistic dates can also demotivate team members and lead to burnout.

Option C) Easier & Realistic - This option is incorrect because setting easier milestone dates may lead to complacency and lack of motivation among the team members. It is important to challenge the team and set aggressive targets to drive performance and ensure timely completion of the project.

Option D) Simple & Realistic - This option is incorrect because simplicity is not the primary consideration when setting project milestone dates. The focus should be on setting aggressive and realistic dates that push the team to achieve their goals efficiently.

The correct answer is option A) Aggressive & Realistic. This option is correct because it highlights the importance of setting challenging but achievable milestone dates to drive performance and ensure timely project completion.

QFD stands for

1. Quality Function Diagram

2. Quality Function Development

3. Quality Function Design

4. Quality Function Deployment

Correct Option: D

#### AI Explanation

To answer this question, you need to understand what QFD (Quality Function Deployment) stands for.

Option A) Quality Function Diagram - This option is incorrect because QFD does not refer to a diagram, but rather a process or methodology. Option B) Quality Function Development - This option is incorrect because QFD does not refer to development, but rather a process or methodology. Option C) Quality Function Design - This option is incorrect because QFD does not refer to design, but rather a process or methodology. Option D) Quality Function Deployment - This option is correct because QFD stands for Quality Function Deployment.

The correct answer is D) Quality Function Deployment. This option is correct because QFD is a process or methodology that is used to translate customer requirements into specific design and production characteristics.

The Independent Variables in DOE are called as _________

1. Factors

2. Response

3. Levels

4. None of above

Correct Option: A

The method that attempts to delineate all possible failures and their effect on a system is called

1. PDCA

2. FMEA

3. Cause-and-effect diagrams

4. Pareto analysis

Correct Option: B

The middle value of a data set when the values are arranged in either ascending or descending order.

2. Mode

3. Mean

4. Standard Deviation

Correct Option: A

The percentage of data values falling within one standard deviation of the center is

1. 62.35%

2. 68.26%

3. 78.38%

Correct Option: B

The purpose of process control is to:

1. Provide a inconsistent level of service to the customer

2. Provide direction for improvement activities

3. Hold the gains created by the improvement activities

4. Break down barriers between groups

Correct Option: C

The value occurring most frequently in a data set is

1. Mean

2. Mode

3. Variable Data

4. Risk

Correct Option: B

#### AI Explanation

To answer this question, you need to understand the concept of mode in statistics.

Option A) Mean - The mean is the average of a set of values. It is calculated by adding up all the values and dividing by the total number of values. The mean does not represent the value occurring most frequently in a data set.

Option B) Mode - The mode is the value that occurs most frequently in a data set. It represents the value with the highest frequency. Therefore, option B is correct.

Option C) Variable Data - Variable data refers to data that can take on different values. It does not indicate the value occurring most frequently in a data set.

Option D) Risk - Risk refers to the possibility of loss, harm, or danger. It is not directly related to finding the value occurring most frequently in a data set.

The correct answer is B) Mode. This option is correct because the mode represents the value occurring most frequently in a data set.

These are set by the customer :

1. Control Limits

2. Specification Limits

3. Sigma Value

4. RPN

Correct Option: B
