Design of Work Systems
Job Design
Job design involves specifying the content
and methods of job
What will be done
Who will do the job
How the job will bob will be done
Where the job will be done

Job Design Success
Successful Job Design must be:
Carried out by experienced personnel with
the necessary training and background
Consistent with the goals of the
organization
In written form
Understood and agreed to by both
management and employees

Specialization in Business: Advantages
Table 7.1
For Management:
For Labor:
1. Simplifies training 1. Low education and
2. High productivity
3. Low wage costs
skill requirements
2. Minimum
responsibilities
3. Little mental effort
needed

Disadvantages
Table 7.1
ForManagement:
ForLabor:
1. Difficult to motivate
quality
1. Monotonous work
2. Limited opportunities
for advancement
2. Worker dissatisfaction,
possibly resulting in
3. Little control over work
absenteeism, high
4. Little opportunity for
turnover, disruptive
self-fulfillment
tactics, poor attention
to quality

Design of Work Systems
Behavioral Approaches to Job Design
Job Enlargement
Job Rotation
Giving a worker a larger portion of the total
task by horizontal loading
Workers periodically exchange jobs
Job Enrichment
Increasing responsibility for planning and
coordination tasks, by vertical loading
7-9
Design of Work Systems
Motivation and Trust
Motivation
Influences quality and productivity
Contributes to work environment
Trust
Influences productivity and employeemanagement relations
7-10
Design of Work Systems
Teams
Benefits of teams
Higher quality
Higher productivity
Greater worker satisfaction
Self-directed teams
Groups of empowered to make certain
changes in their work process

Methods Analysis
Methods analysis
Analyzing how a job gets done
Begins with overall analysis
Moves to specific details
7-12
Design of Work Systems
Methods Analysis
The need for methods analysis can come
from a number of different sources:
Changes in tools and equipment
Changes in product design
or new products
Changes in materials or procedures
Other factors (e.g. accidents, quality
problems)

7.
Identify the operation to be studied
Get employee input
Study and document current method
Analyze the job
Propose new methods
Install new methods
Follow-up to ensure improvements
have been achieved

Analyzing the Job
Flow process chart
Chart used to examine the overall sequence
of an operation by focusing on movements
of the operator or flow of materials
Worker-machine chart
Chart used to determine portions of a work
cycle during which an operator and
equipment are busy or idle

Job Requisition of petty cash D. Kolb 1 of 2
Details of Method
Requisition made by department head
Put in “pick-up” basket
To accounting department
Account and signature verified
Amount approved by treasurer
Amount counted by cashier
Amount recorded by bookkeeper
Petty cash sealed in envelope
Petty cash carried to department
Petty cash checked against requisition
Receipt signed
Petty cash stored in safety box

Motion Study
Motion study is the systematic
study of the human motions used
to perform an operation.
7-17
Design of Work Systems
Motion Study Techniques
Motion study principles - guidelines for
designing motion-efficient work procedures
Analysis of therbligs - basic elemental
motions into which a job can be broken
down
Micromotion study - use of motion pictures
and slow motion to study motions that
otherwise would be too rapid to analyze

Design of Work Systems
Time-based system
Compensation
Compensation based on time an employee
has worked during a pay period
Output-based (incentive) system
Compensation based on the amount of
output an employee produces during a pay
period
