53
Q

TRUE OR FALSE
Linking Product Design, Decisions concerning product design and process selection are not linked and can be made independently of one another.

A

False, correct answer below:
Decisions concerning product design and process selection are directly linked and cannot be made independently of one another.

54
Q

Product Design Decisions: Intermittent Operations

A

Product design - Early stage of product life cycle
Competitive priorities - Delivery, flexibility, and quality
Facility layout - Resources grouped by function
Product strategy - Make-to-order/assemble-to- order
Vertical integration - Low

55
Q

A

Product design - Later stage of product life cycle
Competitive priorities - Cost and quality
Facility layout - Resources arranged in a line
Product strategy -Make-to-stock
Vertical integration -High

56
Q

TRUE OR FALSE

Linking Product Design and Process Selection, Type of operation is directly related to product and service strategy.

A

TRUE!

57
Q

3 basic strategies (Product and service strategies):

A
  • Make-to-stock: in anticipation of demand
  • Assemble-to-order: built from standard components on order
  • Make-to-order: produce to customer specification at time of order
58
Q

Linking Product Design and Process Selection: Degree of Vertical Integration

A

Vertical integration refers to the degree to which a firm performs processes — from raw material to sales. (Think whether outsourcing is best for the company)

In summary, vertical integration is typically a better strategic decision for repetitive operations. For intermittent operations it is generally a poor strategic choice.

59
Q

Technology Decisions, Information technology (IT):

A

is technology that enables storage, processing, and communication of information within and between firms.

60
Q

Technology Decisions, enterprise resource planning (ERP)

A

These are large software programs used for planning and coordinating all resources throughout the entire enterprise. They allow data sharing and communication within and outside of the firm, enabling collaborative decision making.

61
Q

Technology Decisions, Global positioning systems (GPS) A type of wireless technology that uses satellite transmission to communicate exact locations.
How has it impacted process and product design?

A

GPS has even found its use in advertising. Geo-advertising uses GPS to target and push advertising to devices in specific geographic areas. For example, in 2018 the jeans company True Religion needed to promote new products at its retail stores. Using geo-advertising the company sent customized e-mails to customers in areas in which the brand had a high concentration of stores and was able to drive up in-store traffic.

62
Q

Technology Decisions, Radio frequency identification (RFID):

A

A wireless technology that uses memory chips equipped with radio antennas attached to objects used to transmit streams of data.

63
Q

Technology Decisions, Radio frequency identification (RFID),
how has RFID impacted in the process and product design?

A

For example, RFID can be used to identify any product movement, reveal a missing product’s location, or have a shipment of products “announce” its arrival. Empty store shelves can signal that it is time for replenishment using RFID, or low inventories can signal the vendor that it is time to ship more products. RFID can also be used in the service environment, enabling innovative applications in locating and tracking people and assets. (wally world used it to track freshness of their produce out front)

64
Q

Technology Decisions, automation:

A

Using machinery to perform work without human operators.

65
Q

Technology Decisions, automated material handling: (what types)

A

automated guided vehicle (AGV), a small battery-driven truck that moves materials from one location to the other. The AGV is not operated by a human and takes its directions from either an onboard or central computer.
automated storage and retrieval systems (AS/RSs), which are basically automated warehouses.

66
Q

Technology Decisions, Flexible manufacturing system (FMS):

A

A type of automated system that combines the flexibility of intermittent operations with the efficiency of repetitive operations.

67
Q

Technology Decisions, robotics, Numerically controlled (NC) machine;

A

A machine controlled by a computer that can perform a variety of tasks.

68
Q

Technology Decisions, E-manufacturing:

A

Today’s Web-based environment has created numerous opportunities for business collaboration. This includes collaboration in product and process design, where customers, buyers, and designers can share information and jointly make decisions in real time.

69
Q

Technology Decisions, e-manufacturing, computer system’s that aid in e-manufacturing

A

Computer-aided design (CAD) A system that uses computer graphics to design new products.
Computer-integrated manufacturing (CIM) A term used to describe the integration of product design, process planning, and manufacturing using an integrated computer system. The purpose of CIM is to improve how quickly the company can respond to customer needs in terms of product design and availability, as well as quality and productivity, and to improve overall efficiency.
3D Printing 3D Printing is three-dimensional printing technology that deposits materials like plastics and metals in thick layers one atop the other with the process gradually building up one layer at a time until the object is produced.
