specifying the content and methods of jobs. focuses on what will be done and how. Includes:job design, methods and motion analysis, work measurement, compensation

2
Q

Define Efficiency school

A

systematic, logical approach, focused on labour cost reductions

emphasized satisfaction of worker’s wants and needs

5
Q

How a job is (or should be) performed

6

A

The process of determining how long it should take to do a job

Q

Define Specialization

A

The design and development of jobs with a very narrow scope

8
Q

Define Job Enlargement

A

Assigning worker a larger portion of the total task

9
Q

Define Job Rotation

A

Having workers periodically exchange jobs

10
Q

Define Job Enrichment

A

An increase in the level of responsibility for planning and coordination

11
Q

Define Work Team

A

increasing authority, responsibility and trust of workers

12
Q

Define Methods analysis

A

Analyzing how a job gets done, in order to make the job more efficient

13
Q

Define process chart

A

A chart used to examine the overall sequence of an operation by focusing on the movements of the operator or the flow of materials

14
Q

Define Worker-machine chart

A

A chart used to determine the portions of a work cycle during which an operator and equipment are busy or idle

15
Q

Define Motion study

A

The systematic study of the human motions used to perform an operation

16
Q

Define Principles of motion economy

A

Guidelines for designing motion-effective work procedures

a) Principles for use of the body
b) Principles for arrangements of the workplace
c) Principles for the design of tools and equipment

17
Q

Define Therblig

A

Basic elementary motions that make up a job

18
Q

Define Simo Chart

A

A chart that shows the elementary motions performed by each hand, side-by-side, over time

19
Q

Define Work Measurement

A

The process of determining how long it should take to do a job

20
Q

Define Stopwatch time study

A

An approach used to develop a standard time for a job based on observations of one worker taken over a number of cycles

21
Q

Define Observed Time (OT)

A

The average of recorded time

OT=∑xi/n

22
Q

Define Normal Time (NT)

A

The average observed time adjusted for the workers performance
NT=OT x PR
-PR=Performance Rating

23
Q

Define Standard Time (ST)

A

Normal time adjusted for factors such as personal needs, unavoidable delays, adjustments and repairs, waiting for materials, talking to a supervisor, rest breaks, etc
ST=NT x AF
-AF=Allowance Factor

24
Q

Define allowance factor

A

Can be based on either job time or time worked

25
Q

Define Location break-even analysis

A

Identifies the least (fixed and variable) cost location choice based on quantity to be produced

26
Q

Define Factor rating

A

A general approach to evaluating locations that includes quantitative and qualitative factors

27
Q

Define Center of gravity method

A

A method to determine the location of a distribution center that will minimize total distribution cost.It treats distribution cost as a linear function of the distance and the quantity shipped

28
Q

What is the equation for Observed Time?

A

OT=∑xi/n

29
Q

What is the equation for Normal Time?

A

NT=OT x PR

30
Q

What is the equation for Standard Time?

A

ST=NT x AF

31
Q

What is the equation for Allowance Factor?

A

AFjob=1+Ajob

AFday=1/(1-Aday)

32
Q

What is the equation for Number of Cycles?

A

For a given accuracy
-N=2(zs/amX)
For a given target maximum error
-N=2(zs/e)

33
Q

What is the equation for center of gravity

A

mX=∑xiQi/∑Qi

mY=∑yiQi/∑Qi

34
Q

List the 4 activities in work system design

A

1) job design
2) Methods and motion analysis
3) work measurement
4) compensation

35
Q

List the 2 schools of thought in job design

A

1) Efficiency school

2) Behavioural school

36
Q

List the Strengths and Weaknesses of Specialization

A

Strengths - high productivity with low unit cost, and largely responsible for high standard of living in industrailized nations
Weaknesses-monotonous, a source of much worker dissatisfaction

37
Q

List the approaches used to improve the quality of work life

A
  • leave the job as is, but employ only people who like a rigid environment and/or routine work
  • leave the job as is, but pay the employees more
  • mechanize and automate the routine jobs
  • redesign the job
38
