Lecture 6

Question 1

What are the demands of modern manufacturing?

Answer 1

Increase product variety, increase product quality, reduce prices, reduce time-to-market.

Question 2

What shift in manufacturing is driven by these demands?

Answer 2

From “economies of scale” to “economies of flexibility and scope.”

Question 3

What is traditional product development?

Answer 3

A sequential process with separation between design, manufacturing, and other functions.

Question 4

List two common issues in traditional product development.

Answer 4

Slow time-to-market, poor team organization.

Question 5

Define Concurrent Engineering (CE).

Answer 5

A method where product design and manufacturing are developed concurrently, improving time-to-market and collaboration.

Question 6

What are the main components required for successful CE implementation?

Answer 6

Multi-functional teams, design principles and guidelines, supportive technologies, and continuous improvement.

Question 7

How does CE differ from traditional product development?

Answer 7

In CE, all stakeholders collaborate from the beginning, unlike the sequential approach in traditional development.

Question 8

What is Design for Manufacture and Assembly (DFMA)?

Answer 8

A methodology focusing on simplifying design for easier manufacturing and assembly, with fewer parts and simplified processes.

Question 8

What is the purpose of multi-functional teams in CE?

Answer 8

To ensure collaboration across expertise areas like design, manufacturing, marketing, and quality from project start.

Question 9

Provide an example of a DFMA guideline and its advantage.

Answer 9

Guideline: Minimize number of components; Advantage: Reduced assembly cost and easier disassembly for maintenance.

Question 10

What is Design for Quality (DFQ)?

Answer 10

A design approach to meet or exceed customer requirements and ensure robustness and reliability of the product.

Question 11

List some supportive technologies in CE.

Answer 11

Project management software, Product Data Management (PDM), Product Life-cycle Management (PLM), 3D CAD/CAM/CAE, rapid prototyping.

Question 12

What does DFQ emphasize in product improvement?

Answer 12

Improving performance, functionality, reliability, safety, and other quality aspects.

Question 13

What does PLM manage in a product’s lifecycle?

Answer 13

The entire lifecycle from idea, design, and prototyping to manufacturing, customer service, and disposal/recycling.

Question 14

What are the types of risks in CE?

Answer 14

External risks (e.g., regulatory changes), internal risks (e.g., team issues), and result risks (e.g., scheduling issues).

Question 15

What is a risk matrix used for in CE?

Answer 15

To visualize risks by assessing their impact and likelihood, sometimes adding factors like detectability.

Question 16

Name two advantages of Concurrent Engineering.

Answer 16

Reduction in time-to-market and increased quality and customer satisfaction.

Question 17

List two disadvantages of Concurrent Engineering.

Answer 17

It can be difficult to implement, requires organizational changes, and may lead to higher initial project costs.

Question 18

What is Quality Function Deployment (QFD)?

Answer 18

A structured approach to designing products that meet customer requirements, often represented in a “House of Quality.”

Question 19

How does QFD assist in product development?

Answer 19

By translating customer requirements into specific engineering characteristics for product design.
