1. State whether the following statements are true or false.
1. Approaches to improve maintainability of a design are both general and specific.
2. Product designers should only understand and study manufacturing process capability after the design is released.
1F, 2F
1T, 2T
Correct
1T, 2F
Feedback:
Right choice: Statement 1 is true because approaches to improve maintainability of a design are both general and specific. Statement 2 is false because product designers should understand and study manufacturing process capability before the design is released.
1F, 2T

2. State whether the following statements are true or false.
1. The client measures quality through appearance, operation and reliability.
2. A process is a group of activities that produce an output or result.
Wrong
1F, 2F
Feedback:
Not the right choice: Statement 1 is true because quality of performance finds how closely products and services match the intent of the design. Statement 2 is also true because a process is a group of activities that produce an output or result.
Correct
1T, 2T
1T, 2F
1F, 2T

3. Which of the following are the phases involved in reliability quantification?
1. Apportionment
2. Prediction
3. Design of Experiments
4. Fault tree analysis
Correct
1, 2
Wrong
1, 3
Feedback:
Not the right choice: Apportionment is one of the phases involved in reliability quantification but, Design of Experiments is a method developed by Taguchi for determining the optimum target values of product and process parameters.
2, 3
2, 4

4. Which of the following conditions says that a component part is regarded as critical?
1. Components have the ability to influence the final design to identify and prevent future problems.
2. Component has not been tested to the reliability standard.
3. Components have early access to design information.
4. Component has a high population in the equipment.
Correct
2, 4
2, 3
Wrong
4, 3
Feedback:
Not the right choice: Statement 4 is one of the conditions says that a component part is regarded as critical but, statement 3 is not related to the conditions that says a component part is regarded as critical.
2, 1

2. Assume that Manish is a design engineer in Locomotive Pvt Ltd. He was asked by his team leader to design a prototype for XYZ product. When the design was submitted to the quality manager some of the designing aspects of the product were found to be in-efficient. In his report the quality manager highlighted the points that are very essential for a design engineer to keep in mind for achieving a best design. Which of the following points do you think the project manger is trying to convey to the design engineer for achieving a best design?
1. Reliability
2. Maintainability
3. Safety
4. Producibility
Wrong
1, 2, 3
Feedback:
Not the right choice: Along with reliability, maintainability, and safety even producibility is also an important parameter whose knowledge is important for the designer in order to achieve optimum design.
2, 3, 4
1, 2, 4
Correct
1, 2, 3, 4

3. State whether the following statement is true or false.
1. Value engineering is a technique for evaluating the design of a product to make sure that the essential functions are provided at minimal overall cost to the manufacturer or user.
2. Design of manufacturability technique concentrates on simplifying a design to make it more producible.
3. In organisations that use the six sigma approach, the extremely low defect levels desired have an impact on product development.
4. Software available for analysing a design and identifying opportunities for simplifying assembly products, dissects the assembly step by step.
Correct
1T, 2F, 3T, 4T
1F, 2F, 3T, 4T
Wrong
1T, 2F, 3F, 4T
Feedback:
Not the right choice: Statement 1 is true since, value engineering is a technique for evaluating the design of a product to make sure that the essential functions are provided at minimal overall cost to the manufacturer or user. Statement 2 is true because design of manufacturability technique concentrates on simplifying a design to make it more producible. Statement 3 is true since, organisations that use the six sigma approach, the extremely low defect levels desired have an impact on product development. Statement 4 is true since, software available for analysing a design and identifying opportunities for simplifying assembly products, dissects the assembly step by step.

1. One approach to define quality in service sector is the __________ model.


Computer Integrated Manufacturing (CIM)
Correct
SERVQUAL
Computer-Aided Manufacturing (CAM)
Wrong
Flexible Manufacturing System (FMS)
Feedback:
Not the right choice: FMS is a production unit capable of processing a range of discrete products with minimum human intervention. However, it is not an approach to define quality in service sector.o    All Exam Paper For SMU
