Question 1

Which of the following is not true about process design?

Accepted Answer

Process design is not limited to new products or services. It also applies to improving and optimizing existing processes.

Question 2

The process flow diagram for services is called a service blueprint.

Accepted Answer

A service blueprint is a visual representation of the process flow diagram for services, which includes all the steps involved in delivering a service and the interactions between the customer and the service provider. It is used to identify potential areas for improvement in the service delivery process.

Question 3

Heuristic approaches to line balancing guarantee an optimal solution.

Accepted Answer

Heuristic approaches to line balancing do not guarantee an optimal solution, but rather aim to find a good solution that is feasible and easy to implement. These approaches use rules of thumb and common sense to allocate tasks to workstations in a way that balances workload and maximizes efficiency, without necessarily finding the absolute best solution possible.

Question 4

Process design determines the structure of a process-that is,the sequence of operations (the workflow),resources,and controls needed for a particular process

Accepted Answer

Process design is responsible for determining the structure of a process, including the workflow, resources, and controls required to complete the process.

Question 5

Process design determines the structure of a process-that is,the sequence of operations (the workflow),resources,and controls needed for a particular process.

Accepted Answer

Process design is responsible for determining the workflow, resources, and controls necessary for a process. This determines the structure of the process. Therefore, the statement is true.

Question 6

The theoretical minimum number of workstations for a production line is a function of the sum of task times and the cycle time.

Accepted Answer

The theoretical minimum number of workstations for a production line can be calculated using the formula N = total task time / cycle time, where N is the minimum number of workstations required. Therefore, it is a function of the sum of task times and the cycle time.

Question 7

Cycle time is the maximum time allowed at each workstation to complete its assigned tasks on each unit of production before it moves on.

Accepted Answer

Cycle time is the maximum time allowed at each workstation to complete its assigned tasks on each unit of production before it moves on, making the statement true.

Question 8

The overall efficiency of a production line is equal to the percentage idle time times the number of workstations.

Accepted Answer

The overall efficiency of a production line is equal to the percentage of time that the line is producing items, which is calculated as: (total production time - total idle time) / total production time. It is not directly related to the number of workstations.

Question 9

Which of the following is not a factor considered in make-or-buy decisions?

Accepted Answer

Proximity of internal resources is not typically a primary factor considered in make-or-buy decisions. These decisions are more focused on factors like capacity, core capabilities, demand patterns, and the need to protect technology, rather than the geographical location of resources.

Question 10

An advantage of a U-shaped production line is that it facilitates teamwork and flexibility in work assignments.

Accepted Answer

A U-shaped production line allows workers to easily collaborate and switch between different tasks, promoting teamwork and flexibility in work assignments.

Question 11

"Balance delay" is another name for the percentage of idle time in a product layout.

Accepted Answer

Balance delay refers to the percentage of idle time compared to the total time taken to complete a task in a product layout, indicating inefficiency in the production process.

Question 12

A core process is a process that assists the operations of an organization.

Accepted Answer

A core process is a fundamental process that is essential to the business's operations and value proposition, not just assisting operations.

Question 13

Automation is the application of scientific discoveries to the development and innovation of goods and services and/or the processes that produce them.

Accepted Answer

Automation refers to the use of technology and control systems to operate equipment and processes with minimal or no human intervention, rather than the application of scientific discoveries to development and innovation.

Question 14

In which type of operations process are you likely to see products or services produced in low to moderate volumes,with some degree of standardization,and moderate flexibility of the processing equipment used?

Accepted Answer

Batch processing typically involves producing products or services in moderate volumes with some standardization and moderate flexibility of equipment used. It is often used when there is a variety of products that can be grouped into batches for more efficient processing, but not to the extent of continuous processing. Job shops and repetitive production tend to have more variability and customization, while projects are one-off endeavors.

Question 15

A precedence network matrix shows the combination of a product's quantity and variety,and the flexibility of the processes that make it.

Accepted Answer

A precedence network matrix shows the sequence and dependencies of all the tasks required to complete a project, but does not capture information about a product's quantity, variety, or process flexibility.

Question 16

For a production line,daily capacity can be determined by dividing the daily operating time by the line's cycle time.

Accepted Answer

This is correct. Daily capacity can be calculated by dividing the daily operating time by the cycle time of the production line.

Question 17

The goal of line balancing is to assign equal allocations of idle time to all work stations.

Accepted Answer

The goal of line balancing is to allocate work to each work station in a way that balances its workload with the other work stations in the line, minimizing idle time and increasing productivity. The goal is not to assign equal allocations of idle time to all work stations.

Question 18

A swim lane diagram is a process map in which each function/role's activities are in its row/lane.

Accepted Answer

A swim lane diagram is also known as a cross-functional flowchart and shows the handoffs and interactions between different functions or roles involved in a process. Each function or role is represented by its own "swim lane" or horizontal row in the diagram, making it easy to identify who is responsible for which tasks.

Question 19

None of the techniques for line balancing guarantee an optimal solution.

Accepted Answer

Line balancing involves a trade-off between efficiency and other factors such as cost, productivity, and workers' health and safety. Hence, there may not be a single optimal solution for everyone.

Question 20

The closeness ratings approach to design process layouts focuses on one main objective,minimizing the total transportation cost.

Accepted Answer

The closeness ratings approach to design process layouts focuses on arranging departments or workstations to minimize the costs of material handling and to improve communication and interaction, rather than solely on minimizing total transportation cost.
