(58)

58

1.2.2 Engineering functions:

Testing

• Test engineers are responsible for designing and

implementing tests to verify the integrity, reliability and quality of products. Test engineer devises ways to simulate the conditions of a product will be subjected to during its life.

• Example: testing of a pacemaker for regulating a

patient’s heart which is designed to last several decades (the test cannot take 20 years and must simulate conditions within the human body)

(59)

59

1.2.2 Engineering functions:

Design (1)

• This is where the largest number of engineers

are employed

• The design engineer is responsible for providing

the detailed specifications of the products

• They use modern computer design tools and are

often supported by technicians trained in computer drafting software

(60)

60

1.2.2 Engineering functions:

Design (2)

• The design engineer also must verify that the

part meets the reliability and safety standards established for the product

• In the world of ever increasing competition, the

design engineer must also involve manufacturing engineers in the design process. Cost is a critical factor and may be the difference between success and failure.

(61)

61

1.2.2 Engineering products:

Analysis

• Analysis engineers use mathematical models

and computational tools to provide the necessary information to design, development or research engineers to help them do their jobs

• Analysis engineers typically are specialists in a

technology area, for example: electromagnetic field, microelectronic, signal processing, electromechanical energy conversion, stability, heat transfer, fluid mechanics, and so on

(62)

62

1.2.2 Engineering functions:

Systems

• Systems engineers work with the overall design,

development, manufacture and operation of a complete system or product

• Systems engineers are responsible for ensuring

that the components interface properly and work as a complete unit, and responsible for identifying the overall design requirements

(63)

63

1.2.2 Engineering functions:

Manufacturing

teams of individuals, from technicians to managers

• They are responsible for developing the

processes for taking raw materials and changing them into the finished pieces

• They identify high cost or high risk operations in

(64)

64

1.2.2 Engineering functions:

Operation & Maintenance

• The operations engineer oversees the ongoing

performance of the production facility

• They must have a wide range of expertise

dealing with the mechanical and electrical issues

• They must coordinate the service schedule of

the technicians to ensure efficient service of the machinery, minimizing its down-time impact on production

(65)

65

1.2.2 Engineering functions:

Technical Support

• A technical support engineer serves as the link

between customer and product and assists with installation and setup

• Modern technical support is being used as an

added service

• Technical support engineer should have good

communication skills, and know how to get in-depth knowledge when necessary

(66)

66

1.2.2 Engineering functions:

Customer Support

• Customer support engineers must have

experience with the products and customer, and also some business training

• The customer support person work with

technical support engineers to ensure proper customer satisfaction

(67)

67

1.2.2 Engineering functions:

Sales

• Sales engineers must have the technical

background to answer customer questions and concerns

• They must have interpersonal skills conducive to

effective selling

• As technology continues to advance, more and

more products become technically sophisticated, leading to an ever-increasing demand for sales engineers

(68)

68

1.2.2 Engineering functions:

Consulting

• Consulting engineers are either self-employed or

they work for a firm that provides technical expertise to customer

• Many large companies do not have technical

experts on staff in all areas, therefore they use consultants to handle issues they cannot solve

• Consulting work examples: technology

innovation, design, installation, maintenance, …

• Consulting engineers may also evaluate the

(69)

69

1.2.2 Engineering functions:

Management

• In many instances, engineers work themselves into

project management positions, and eventually into full-time managment

• Engineers are chosen for their technical ability, their

problem-solving ability and their leadership skills
